Definitions
- This invention relates to abuse resistant, impact resistant and fire resistant building materials, and more particularly, to a single piece laminate composite building material of fiber-cement and gypsum.
- the interior wallboard market has been dominated by the use of gypsum wallboard products for many years.
- the gypsum wallboard typically comprises thin paper layers wrapped around a gypsum core. For example, one paper layer covers the face and long edges of the board, and the second paper layer usually covers the back surface of the board.
- the core is predominantly gypsum, and can be modified with additives such as glass fiber, vermiculite and mica to improve fire resistance.
- Gypsum In addition to fire resistance, abuse resistance is another desired quality in wallboards. Gypsum has poor abuse resistance compared to other wallboard materials such as wood or masonry. The paper surface of gypsum wallboard is easily damaged by impact such as scuffing, indentation, cracking or penetration with hard or soft body objects such as furniture, trolleys, toys, sports equipment and other industrial or residential furnishings. Such wall abuse is typical in high traffic rooms such as corridors, family living areas, gymnasiums or change rooms.
- Gypsum wallboard manufacturers have made modifications to their gypsum wallboards to improve their abuse resistance.
- One method was to bond a plastic film to the back of the wall panel to resist penetration of the impact bodies into the framed wall cavity.
- Another method was to make a fiber-gypsum wall panel with fiber-gypsum outer layers formed onto a gypsum-based core. These products typically have improved surface abuse resistance to the paper surface of normal gypsum wallboard.
- Similar gypsum-based or cement gypsum-based compositions are typically described in U.S. Pat. No. 5,817,262 and U.S. Pat. No. 5,718,759.
- Fiber cement has an advantage over gypsum panel with respect to surface abuse resistance such as wear and abrasion.
- One disadvantage of fiber cement by itself as a wall panel is that it does not have a fire resistance rating comparable to gypsum wall panels of equal thickness.
- Another disadvantage of fiber cement by itself is that it is significantly heavier than gypsum wall panels of equivalent thickness. For example, a 1 hour fire resistance-rated wall system with fiber cement requires mineral insulation in the wall cavity or a sub-layer of fire rated gypsum wall panel to achieve a 1 hour fire resistance rating when tested in accordance with ASTM E-119.
- a 2-layer system of 1 ⁇ 4′′ fiber cement over 5 ⁇ 8′′ type X fire rated gypsum wallboard has been used to achieve both fire resistance and abuse resistance.
- Such a system is described in Gypsum Association—Fire Resistance Design Manual—GA FILE NO.
- WP 1295 Gypsum wallboard, steel studs, fiber-cement board proprietary system.
- This two piece system is disadvantageous because it is significantly heavier than single-layer gypsum wallboards.
- the 2-layer wallboards require nearly double the amount of labor for installation because two separate wall panels must be installed instead of a single panel.
- a single piece building material that has good abuse resistance, impact resistance and fire resistance.
- This building material should also be light, easy to manufacture and compatible with standard building material sizes.
- fire resistance it would be especially advantageous for such a material to have a fire resistance rating of at least one hour as measured by ASTM E119.
- a building material comprising fiber-cement laminated to gypsum to form a single piece laminate composite.
- This single piece laminate composite exhibits improved fire resistance and surface abuse resistance, but achieves these properties without the excessive weight and thickness of two piece systems. Additionally, because of the reduced thickness, the preferred laminate building material is easier to cut and is quicker and easier to install than two piece systems. Furthermore, forming the fiber-cement and gypsum into a single piece laminate eliminates the need to install two separate pieces of building material, thereby simplifying installation.
- One object of the invention is to provide a building board product suitable for applications requiring surface abuse resistance, improved impact resistance and a 1-hour fire resistance rating (as measured, for example, by ASTM E-119) without cavity insulation at a panel thickness of 5 ⁇ 8′′, installed on each side of a wall frame.
- the surface abuse resistance is measured by abrasion tests such as ASTM D4977-98b (Standard Test Method for Granule Adhesion to Mineral Surfaced roofing) and also indentation tests such as ASTM D5420 (Impact Resistance of Flat, Rigid Plastic Specimen by Means of a Striker by a Falling Weight (Gardner Impact)).
- the panel impact resistance is typically measured by, for example, ASTM E695 (Measuring Relative Resistance of Wall, Floor and Roof Construction to Impact Loading), and ISO 7892 (Vertical Building Elements—Impact Resistance Tests—Impact Bodies and General Test Procedures), or other suitable impact or abrasion tests.
- FIG. 1 is a perspective view of a single piece laminate composite comprising fiber-cement laminated to gypsum.
- FIG. 2 is a cross-sectional view of the single piece laminate composite of FIG. 1 , showing the fiber-cement and gypsum adhered together using an adhesive.
- a preferred building material 40 is comprised of a fiber-cement layer 10 laminated to gypsum layer 20 , creating a single piece laminate composite.
- FIG. 2 illustrates that the fiber cement layer 10 may be laminated to the gypsum layer 20 using an adhesive 30 , the thickness of which is exaggerated in FIG. 2 for illustration purposes, as described in further detail below.
- the fiber-cement and gypsum components can take any form necessary, including, but not limited to, panels, sheets, skins, boards, or the like.
- the thickness of a fiber-cement sheet 10 is between about 1/32′′ and 1 ⁇ 4′′.
- the fiber-cement sheet 10 is about 1 ⁇ 8′′ thick, plus or minus about 1/16′′.
- a gypsum panel 20 typically has a thickness between about 1 ⁇ 4′′ to 3 ⁇ 4′′, more preferably about 1 ⁇ 2′′. It will be appreciated that other thicknesses for the fiber-cement sheet 10 and the gypsum panel 20 may be used.
- the preferred weight is about 2.5 to 3 lbs/square foot, more preferably about 2.77 lbs/square foot for a 5 ⁇ 8′′ thick composite wallboard.
- One preferred embodiment of the invention is a composite panel that is manufactured by bonding together a paper-faced 1 ⁇ 2′′ type X gypsum wallboard to 1 ⁇ 8′′ thick fiber cement panel.
- ASTM C 36 describes a type X gypsum board to have not less than 45 minutes fire resistance rating for boards 1 ⁇ 2′′ thick, applied parallel with and on each side of load bearing 2′′ ⁇ 4′′ wood studs spaced 16′′ on center with 6D coated nail, 17 ⁇ 8′′ long 0.095′′ diameter shank, 1 ⁇ 4′′ diameter head, spaced 7′′ on center with the gypsum joints staggered 16′′ on each side of the partition and tested in accordance with ASTM E 119.
- Type X gypsum panel is a 1 ⁇ 2′′ thick HARDIROCK® MAX “C”TM, described in the table below.
- This gypsum panel has an improved Type X fire resistance rated core and is manufactured for commercial projects where building codes require specific levels of fire resistance and sound reduction.
- the 5 ⁇ 8′′ thick board is designed to provide greater fire resistance than standard Fire XTM board and achieves fire and sound rating with less weight.
- Application information is available in the Gypsum Association Fire Resistance Design Manual GA -600, Underwriter's Laboratories, Inc. Fire Resistance Directory.
- the face of the gypsum panel 20 bonded to the fiber-cement 10 does not necessarily require a paper face, and the gypsum panel 20 may be bonded directly to the fiber-cement 10 .
- a preferred gypsum panel 20 may also have a glass or polymeric fiber mat or woven mesh combined into the panel on either the front or back surface, either on the outside or the inside of the paper. This can be done for two reasons. First, it can be used to improve the impact resistance of the gypsum panel 20 by itself. Second, it can be used to improve the impact resistance of the gypsum panel as part of the composite wallboard 40 .
- the preferred composite wallboard 40 can be utilized in most interior wallboard installations.
- the preferred composite wallboard 40 is installed such that the fiber-cement side of the wallboard 40 faces outward to provide an abrasion and indentation resistant surface to traffic, and the gypsum side of the wallboard 40 is installed against the supporting framing, with the synergistic combination of the fiber-cement and the gypsum wallboard providing the fire resistance rating and strength of the panel.
- Neither the preferably 1 ⁇ 2′′ gypsum panel 20 nor the preferably 1 ⁇ 8′′ fiber-cement sheet 10 provides the 1-hour fire resistance rating in isolation, but rather the combination of the two materials in a laminated composite 40 has been tested in a symmetrical wall system and achieved a 1 hour fire resistance rating on a typical steel framing used in commercial building partitions. Results of a fire resistance test conducted on this composite panel are provided below.
- the supporting framing is typically 20 or 25 gauge steel framing, or wood framing such as 2′′ ⁇ 4′′ Douglas Fir softwood.
- the wallboard 40 can be fastened to the steel studs with suitable screws such as 6 gauge ⁇ 11 ⁇ 8′′ Type S Bugle Head drywall or self-drilling screws.
- the wallboard 40 can be fastened to wood studs with suitable nails or screws such as 13 ⁇ 4′′ long cup-head gypsum wallboard nails or 6 gauge ⁇ 11 ⁇ 8′′ Type S Bugle Head drywall screws.
- the preferred wallboard 40 is designed for use in wall assemblies that are subject to surface abuse and penetration. Such wall assemblies are typically found in schools, public housing, public buildings, interior garage walls, corridors, gymnasiums, change rooms, and correctional and healthcare facilities.
- the material can be cut with a carbide-tipped score and snap knife, power shears or circular saw optionally with dust control.
- Fiber cement has the attributes of durability, resistance to moisture damage, low maintenance, resistance to cracking, rotting or delamination, resistance to termites and non-combustibility.
- the fiber cement layer 10 resists damage from extended exposure to humidity, rain, snow, salt air and termites.
- the layer is dimensionally stable and under normal conditions will not crack, rot or delaminate.
- the basic composition of a preferred fiber-cement panel 10 is about 20% to 60% Portland cement, about 20% to 70% ground silica sand, about 5% to 12% cellulose fiber, and about 0% to 6% select additives such as mineral oxides, mineral hydroxides and water. Platelet or fibrous additives, such as, for example, wollastonite, mica, glass fiber or mineral fiber, may be added to improve the thermal stability of the fiber-cement.
- the dry density of a preferred fiber-cement panel 10 is typically about 1.3 to 1.4 g/cm 3 but can be modified by pressing the material to dry densities up to 2.0 g/cm 3 or by addition of density modifiers such as unexpanded or expanded vermiculite, perlite, clay, shale or low bulk density (about 0.06 to 0.7 g/cm 3 ) calcium silicate hydrates.
- the flexural strength of a preferred fiber-cement panel 10 is 1850 psi along the panel, and 2500 psi across the panel.
- a preferred fiber-cement panel 10 has a non-combustible surface and shows no flame support or loss of integrity when tested in accordance with ASTM test method E136. When tested in accordance with ASTM test method E84, a preferred fiber-cement panel 10 exhibits the following surface burning capabilities:
- a preferred panel is comprised of a 1 ⁇ 8′′ nominal thickness fiber cement sheet laminated to a 1 ⁇ 2′′ thick type X fire resistant gypsum board.
- the gypsum panel is preferably manufactured with square edges.
- An adhesive 30 as shown in FIGS. 1 and 2 above such as polyvinyl acetate (PVA) is spread over the surface of the gypsum panel and 1 ⁇ 8′′ thick fiber cement is placed over the surface and is typically pressed at about 38 psi, in a stacked configuration, for approximately 30 minutes.
- PVA polyvinyl acetate
- One preferred adhesive is Sun Adhesives polyvinyl acetate (PVA) adhesive #54-3500 supplied by Sun Adhesives, a division of Patrick Industries.
- the adhesive is most preferably a low cost adhesive such as PVA
- other organic or inorganic adhesives may be used, such as water-based polymeric adhesives, solvent-based adhesives, thermoset adhesives, natural polymers such as modified starches, liquid moisture cure or reactive hot melt adhesives such as polyurethane, and heat or fire resistant adhesives.
- the adhesive 30 is preferably applied by a roll-coater process whereby the gypsum panel 20 is preferably cleaned to remove dust and debris before the adhesive 30 is applied to the smooth face.
- the adhesive 30 is preferably spread evenly over the entire surface of the gypsum panel 20 .
- the wet film thickness of the adhesive 30 when measured with a standard “wet film thickness gauge,” will preferably not be less than about 4.5 mil and preferably will not exceed about 6 mil.
- the fiber-cement panel 10 is placed on top of the gypsum panel 20 , which is coated with adhesive 30 , squared to the edges of the gypsum panel 20 , and then stacked.
- the completed stack is preferably cured in a press under a load of about 37.5 ⁇ 2.5 psi for preferably no less than about 30 minutes.
- the panels then preferably have the fiber cement surface sanded and the long edges machined with an abrasive wheel such as diamond grit to form a tapered edge.
- the machine sanding preferably utilizes three sanding heads.
- the grades of sanding belts preferably range from 40 grit to 220 grit.
- the long edges are machine tapered to allow for setting compound, joint reinforcing tape and finishing compounds during flush jointing on installation.
- the surface of the product is preferably sealed with an acrylic emulsion to reduce the surface water absorption to make it easier to paint and to improve paint adhesion.
- the fiber-cement surface of the composite wallboard 40 may be optionally sealed with an acrylic sealer such as UCAR 701 to facilitate on the job finishing. This can be achieved with a suitable latex paint which may be sprayed, rolled or brush applied for wallpaper or texture finishes. It will also be appreciated that sanding the fiber-cement panel 10 is optional in order to improve the finish of the fiber-cement surface. Furthermore, it will be appreciated that sanding can be done before or after the fiber-cement panel 10 is laminated to the gypsum panel 20 . It will be appreciated that a roll press lamination process may also be used, with a suitable pressure sensitive adhesive.
- an acrylic sealer such as UCAR 701
- a novel feature of the preferred embodiments of the present invention is that neither the 1 ⁇ 2′′ gypsum wallboard or the 1 ⁇ 8′′ fiber cement sheet, by themselves, provide altogether, the 1-hour fire resistance rating, surface abuse and impact resistance. However, laminating the two materials together provides the l-hour fire resistance in a symmetrical wall system when tested to ASTM E119 and an improved level of surface abuse resistance and impact resistance.
- the preferred panel also has the advantages of improved flexural strength and nail pull through strength and less humidified deflection compared to the individual components of the preferred invention or a typical type X gypsum wallboard of the same thickness (5 ⁇ 8′′ thick).

Abstract
Description
- This application is a continuation of prior U.S. application Ser. No. 10/437,344, filed May 13, 2003 which is a continuation of 09/685,637, filed Oct. 10, 2000, now U.S. Letters Pat. No. 6,562,444, and also claims the benefit of Provisional Application Ser. No. 60/158,600, filed Oct. 8, 1999, all of which are hereby incorporated by reference in their entirety.
- 1. Field of the Invention
- This invention relates to abuse resistant, impact resistant and fire resistant building materials, and more particularly, to a single piece laminate composite building material of fiber-cement and gypsum.
- 2. Description of the Related Art
- The interior wallboard market has been dominated by the use of gypsum wallboard products for many years. The gypsum wallboard typically comprises thin paper layers wrapped around a gypsum core. For example, one paper layer covers the face and long edges of the board, and the second paper layer usually covers the back surface of the board. The core is predominantly gypsum, and can be modified with additives such as glass fiber, vermiculite and mica to improve fire resistance.
- In addition to fire resistance, abuse resistance is another desired quality in wallboards. Gypsum has poor abuse resistance compared to other wallboard materials such as wood or masonry. The paper surface of gypsum wallboard is easily damaged by impact such as scuffing, indentation, cracking or penetration with hard or soft body objects such as furniture, trolleys, toys, sports equipment and other industrial or residential furnishings. Such wall abuse is typical in high traffic rooms such as corridors, family living areas, gymnasiums or change rooms.
- Gypsum wallboard manufacturers have made modifications to their gypsum wallboards to improve their abuse resistance. One method was to bond a plastic film to the back of the wall panel to resist penetration of the impact bodies into the framed wall cavity. Another method was to make a fiber-gypsum wall panel with fiber-gypsum outer layers formed onto a gypsum-based core. These products typically have improved surface abuse resistance to the paper surface of normal gypsum wallboard. Similar gypsum-based or cement gypsum-based compositions are typically described in U.S. Pat. No. 5,817,262 and U.S. Pat. No. 5,718,759.
- One material having significant abuse resistance is fiber-cement. Fiber cement has an advantage over gypsum panel with respect to surface abuse resistance such as wear and abrasion. One disadvantage of fiber cement by itself as a wall panel is that it does not have a fire resistance rating comparable to gypsum wall panels of equal thickness. Another disadvantage of fiber cement by itself is that it is significantly heavier than gypsum wall panels of equivalent thickness. For example, a 1 hour fire resistance-rated wall system with fiber cement requires mineral insulation in the wall cavity or a sub-layer of fire rated gypsum wall panel to achieve a 1 hour fire resistance rating when tested in accordance with ASTM E-119.
- A 2-layer system of ¼″ fiber cement over ⅝″ type X fire rated gypsum wallboard has been used to achieve both fire resistance and abuse resistance. Such a system is described in Gypsum Association—Fire Resistance Design Manual—GA FILE NO. WP 1295—Gypsum wallboard, steel studs, fiber-cement board proprietary system. This two piece system is disadvantageous because it is significantly heavier than single-layer gypsum wallboards. Additionally, the 2-layer wallboards require nearly double the amount of labor for installation because two separate wall panels must be installed instead of a single panel. Also, the extra thickness of the 2-layer systems (⅝″+¼″=⅞″) is not compatible with most door jamb widths.
- Accordingly, what is needed is a single piece building material that has good abuse resistance, impact resistance and fire resistance. This building material should also be light, easy to manufacture and compatible with standard building material sizes. With respect to fire resistance, it would be especially advantageous for such a material to have a fire resistance rating of at least one hour as measured by ASTM E119.
- Briefly stated, the needs addressed above are satisfied in one embodiment by a building material comprising fiber-cement laminated to gypsum to form a single piece laminate composite. This single piece laminate composite exhibits improved fire resistance and surface abuse resistance, but achieves these properties without the excessive weight and thickness of two piece systems. Additionally, because of the reduced thickness, the preferred laminate building material is easier to cut and is quicker and easier to install than two piece systems. Furthermore, forming the fiber-cement and gypsum into a single piece laminate eliminates the need to install two separate pieces of building material, thereby simplifying installation.
- One object of the invention is to provide a building board product suitable for applications requiring surface abuse resistance, improved impact resistance and a 1-hour fire resistance rating (as measured, for example, by ASTM E-119) without cavity insulation at a panel thickness of ⅝″, installed on each side of a wall frame. The surface abuse resistance is measured by abrasion tests such as ASTM D4977-98b (Standard Test Method for Granule Adhesion to Mineral Surfaced Roofing) and also indentation tests such as ASTM D5420 (Impact Resistance of Flat, Rigid Plastic Specimen by Means of a Striker by a Falling Weight (Gardner Impact)). The panel impact resistance is typically measured by, for example, ASTM E695 (Measuring Relative Resistance of Wall, Floor and Roof Construction to Impact Loading), and ISO 7892 (Vertical Building Elements—Impact Resistance Tests—Impact Bodies and General Test Procedures), or other suitable impact or abrasion tests.

FIG. 1 is a perspective view of a single piece laminate composite comprising fiber-cement laminated to gypsum. -
FIG. 2 is a cross-sectional view of the single piece laminate composite ofFIG. 1 , showing the fiber-cement and gypsum adhered together using an adhesive. - The preferred embodiments of the present invention illustrated below describe a single piece laminate composite wallboard system. It will be appreciated, however, that the present invention is not limited to wallboards, but can be utilized for any application where an abuse resistant, impact resistant and fire resistant building material is desired.
- As seen in
FIG. 1 , a preferredbuilding material 40 is comprised of a fiber-cement layer 10 laminated togypsum layer 20, creating a single piece laminate composite.FIG. 2 illustrates that thefiber cement layer 10 may be laminated to thegypsum layer 20 using an adhesive 30, the thickness of which is exaggerated inFIG. 2 for illustration purposes, as described in further detail below. It will be appreciated that the fiber-cement and gypsum components can take any form necessary, including, but not limited to, panels, sheets, skins, boards, or the like. In one preferred embodiment, the thickness of a fiber-cement sheet 10 is between about 1/32″ and ¼″. More preferably, the fiber-cement sheet 10 is about ⅛″ thick, plus or minus about 1/16″. Agypsum panel 20 typically has a thickness between about ¼″ to ¾″, more preferably about ½″. It will be appreciated that other thicknesses for the fiber-cement sheet 10 and thegypsum panel 20 may be used. The preferred weight is about 2.5 to 3 lbs/square foot, more preferably about 2.77 lbs/square foot for a ⅝″ thick composite wallboard. - One preferred embodiment of the invention is a composite panel that is manufactured by bonding together a paper-faced ½″ type X gypsum wallboard to ⅛″ thick fiber cement panel. ASTM C 36 describes a type X gypsum board to have not less than 45 minutes fire resistance rating for boards ½″ thick, applied parallel with and on each side of load bearing 2″×4″ wood studs spaced 16″ on center with 6D coated nail, 1⅞″ long 0.095″ diameter shank, ¼″ diameter head, spaced 7″ on center with the gypsum joints staggered 16″ on each side of the partition and tested in accordance with ASTM E 119. One preferred ½″ Type X gypsum panel is a ½″ thick HARDIROCK® MAX “C”™, described in the table below. This gypsum panel has an improved Type X fire resistance rated core and is manufactured for commercial projects where building codes require specific levels of fire resistance and sound reduction. The ⅝″ thick board is designed to provide greater fire resistance than standard Fire X™ board and achieves fire and sound rating with less weight. Application information is available in the Gypsum Association Fire Resistance Design Manual GA-600, Underwriter's Laboratories, Inc. Fire Resistance Directory.
HARDIROCK ® MAX “C” ™ THICKNESS ½″ (12.7 mm) inches (mm) WIDTH 4′ (1219 mm) feet (mm) STANDARD LENGTHS 8′, 9′, 10′ feet STANDARD EDGES Tapered or square APPROX WEIGHT 1.8 lbs/sq ft (8.8 kg/m2) lbs/sq ft (kg/m2) ASTM SPECS C 36 - It will be appreciated that the face of the
gypsum panel 20 bonded to the fiber-cement 10 does not necessarily require a paper face, and thegypsum panel 20 may be bonded directly to the fiber-cement 10. Apreferred gypsum panel 20 may also have a glass or polymeric fiber mat or woven mesh combined into the panel on either the front or back surface, either on the outside or the inside of the paper. This can be done for two reasons. First, it can be used to improve the impact resistance of thegypsum panel 20 by itself. Second, it can be used to improve the impact resistance of the gypsum panel as part of thecomposite wallboard 40. - The preferred
composite wallboard 40 can be utilized in most interior wallboard installations. The preferredcomposite wallboard 40 is installed such that the fiber-cement side of thewallboard 40 faces outward to provide an abrasion and indentation resistant surface to traffic, and the gypsum side of thewallboard 40 is installed against the supporting framing, with the synergistic combination of the fiber-cement and the gypsum wallboard providing the fire resistance rating and strength of the panel. Neither the preferably ½″gypsum panel 20 nor the preferably ⅛″ fiber-cement sheet 10 provides the 1-hour fire resistance rating in isolation, but rather the combination of the two materials in alaminated composite 40 has been tested in a symmetrical wall system and achieved a 1 hour fire resistance rating on a typical steel framing used in commercial building partitions. Results of a fire resistance test conducted on this composite panel are provided below. - The supporting framing is typically 20 or 25 gauge steel framing, or wood framing such as 2″×4″ Douglas Fir softwood. The
wallboard 40 can be fastened to the steel studs with suitable screws such as 6 gauge×1⅛″ Type S Bugle Head drywall or self-drilling screws. Thewallboard 40 can be fastened to wood studs with suitable nails or screws such as 1¾″ long cup-head gypsum wallboard nails or 6 gauge×1⅛″ Type S Bugle Head drywall screws. Thepreferred wallboard 40 is designed for use in wall assemblies that are subject to surface abuse and penetration. Such wall assemblies are typically found in schools, public housing, public buildings, interior garage walls, corridors, gymnasiums, change rooms, and correctional and healthcare facilities. The material can be cut with a carbide-tipped score and snap knife, power shears or circular saw optionally with dust control. - Fiber Cement
- The art of manufacturing cellulose fiber reinforced cement for use in a fiber-cement sheet or
skin 10 is described in the Australian Patent AU 515151 and U.S. Pat. No. 6,030,447, the entirety of which is incorporated by reference. Fiber cement has the attributes of durability, resistance to moisture damage, low maintenance, resistance to cracking, rotting or delamination, resistance to termites and non-combustibility. Thus, thefiber cement layer 10 resists damage from extended exposure to humidity, rain, snow, salt air and termites. The layer is dimensionally stable and under normal conditions will not crack, rot or delaminate. - The basic composition of a preferred fiber-
cement panel 10 is about 20% to 60% Portland cement, about 20% to 70% ground silica sand, about 5% to 12% cellulose fiber, and about 0% to 6% select additives such as mineral oxides, mineral hydroxides and water. Platelet or fibrous additives, such as, for example, wollastonite, mica, glass fiber or mineral fiber, may be added to improve the thermal stability of the fiber-cement. - The dry density of a preferred fiber-
cement panel 10 is typically about 1.3 to 1.4 g/cm3 but can be modified by pressing the material to dry densities up to 2.0 g/cm3 or by addition of density modifiers such as unexpanded or expanded vermiculite, perlite, clay, shale or low bulk density (about 0.06 to 0.7 g/cm3) calcium silicate hydrates. - The flexural strength of a preferred fiber-
cement panel 10, typically based on Equilibrium Moisture Content in accordance with ASTM test method C1185, is 1850 psi along the panel, and 2500 psi across the panel. - A preferred fiber-
cement panel 10 has a non-combustible surface and shows no flame support or loss of integrity when tested in accordance with ASTM test method E136. When tested in accordance with ASTM test method E84, a preferred fiber-cement panel 10 exhibits the following surface burning capabilities: - Flame spread: 0
- Fuel Contributed: 0
- Smoke Developed: 5.
- Lamination Process
- A preferred panel is comprised of a ⅛″ nominal thickness fiber cement sheet laminated to a ½″ thick type X fire resistant gypsum board. The gypsum panel is preferably manufactured with square edges. An adhesive 30 as shown in
FIGS. 1 and 2 above such as polyvinyl acetate (PVA) is spread over the surface of the gypsum panel and ⅛″ thick fiber cement is placed over the surface and is typically pressed at about 38 psi, in a stacked configuration, for approximately 30 minutes. One preferred adhesive is Sun Adhesives polyvinyl acetate (PVA) adhesive #54-3500 supplied by Sun Adhesives, a division of Patrick Industries. While the adhesive is most preferably a low cost adhesive such as PVA, other organic or inorganic adhesives may be used, such as water-based polymeric adhesives, solvent-based adhesives, thermoset adhesives, natural polymers such as modified starches, liquid moisture cure or reactive hot melt adhesives such as polyurethane, and heat or fire resistant adhesives. - The adhesive 30 is preferably applied by a roll-coater process whereby the
gypsum panel 20 is preferably cleaned to remove dust and debris before the adhesive 30 is applied to the smooth face. The adhesive 30 is preferably spread evenly over the entire surface of thegypsum panel 20. The wet film thickness of the adhesive 30, when measured with a standard “wet film thickness gauge,” will preferably not be less than about 4.5 mil and preferably will not exceed about 6 mil. The fiber-cement panel 10 is placed on top of thegypsum panel 20, which is coated with adhesive 30, squared to the edges of thegypsum panel 20, and then stacked. The completed stack is preferably cured in a press under a load of about 37.5±2.5 psi for preferably no less than about 30 minutes. The panels then preferably have the fiber cement surface sanded and the long edges machined with an abrasive wheel such as diamond grit to form a tapered edge. The machine sanding preferably utilizes three sanding heads. The grades of sanding belts preferably range from 40 grit to 220 grit. The long edges are machine tapered to allow for setting compound, joint reinforcing tape and finishing compounds during flush jointing on installation. The surface of the product is preferably sealed with an acrylic emulsion to reduce the surface water absorption to make it easier to paint and to improve paint adhesion. - The fiber-cement surface of the
composite wallboard 40 may be optionally sealed with an acrylic sealer such as UCAR 701 to facilitate on the job finishing. This can be achieved with a suitable latex paint which may be sprayed, rolled or brush applied for wallpaper or texture finishes. It will also be appreciated that sanding the fiber-cement panel 10 is optional in order to improve the finish of the fiber-cement surface. Furthermore, it will be appreciated that sanding can be done before or after the fiber-cement panel 10 is laminated to thegypsum panel 20. It will be appreciated that a roll press lamination process may also be used, with a suitable pressure sensitive adhesive. - Testing
- Abuse resistance tests were conducted on one preferred laminate composite panel. This preferred panel provided superior impact resistance to the common type X fire resistant gypsum wallboard. The preferred panel also has superior abrasion resistance to both the common type X fire resistant gypsum wallboard and the abuse resistant gypsum based panels.
- A novel feature of the preferred embodiments of the present invention is that neither the ½″ gypsum wallboard or the ⅛″ fiber cement sheet, by themselves, provide altogether, the 1-hour fire resistance rating, surface abuse and impact resistance. However, laminating the two materials together provides the l-hour fire resistance in a symmetrical wall system when tested to ASTM E119 and an improved level of surface abuse resistance and impact resistance.
- It is believed that the preferred panel also has the advantages of improved flexural strength and nail pull through strength and less humidified deflection compared to the individual components of the preferred invention or a typical type X gypsum wallboard of the same thickness (⅝″ thick).
- The preferred composite also has the novel features of fire and abuse characteristics in a single wallboard or a single piece system. Prior fire resistance rated and abuse resistant systems that utilize fiber cement required a two layer system over the supporting framework. There is considerable advantage with the preferred composite in reduced material and quicker installation of a single piece system versus a 2-layer system. The two layer system required installation of ⅝″ type X gypsum wallboard followed by the installation of ¼″ fiber cement over the top. The total thickness of these 2 layers adds up to ⅞″ of material versus ⅝″ of material with the preferred laminated composite of the present invention.
- Thus, in one embodiment the present invention provides a single piece system that is at least about one hour fire resistance-rated and abuse resistant. This reduces the amount of time to install compared to the 2 layer system, lowers the mass of the wall unit per square foot compared to the 2 layer system, and requires less fixtures per wall for installing panel compared to the 2 layer system. Moreover, the material is easily cut with power shears, which is a quick and easy method of cutting.
- The material also is abrasion resistant, indentation resistant and impact resistant (soft body and hard body), as illustrated in the tables below.
- Surface-abuse and impact resistance can be determined by methods used in such tests as ASTM D 4977-98b (Standard Test Method for Granule Adhesion to Mineral Surfaced Roofing by Abrasion), ASTM D 5420 (Impact Resistance of Flat, Rigid Plastic Specimen by Means of a Striker by a Falling Weight (Gardner Impact)), ASTM E 695 (Measuring Relative Resistance of Wall, Floor and Roof Construction to Impact Loading), ISO 7892 (Vertical Building Elements—Impact Resistance Tests—Impact Bodies and General Test Procedures), or other suitable impact or abrasion tests. Fire resistance can be measured by tests such as ASTM E 119 (Standard Test Methods for Fire Tests of Building Construction and Materials), UL263, UBC 7-1, NFPA 251, ANSI A2.1, or other suitable fire resistance tests. One ⅝″ thick laminate composite embodiment, comprising ⅛″ fiber-cement laminated on top of a ½ Hardirock Max “C” Gypsum panel, achieved superior abrasion and impact resistance as illustrated in the tables below.

Fasteners were placed approximately 3″ in from panel comers and approximately ⅜″ in from panel edges. On the fire side, one layer of ⅛″ thick Hardiboard® fiber-cement face skin laminated to ½″ thick Hardirock® “Max C”™ gypsum board was applied perpendicular (horizontally) to 20 GA.×3⅝″ steel studs 24″ o.c. with minimum 1″ long Type S drywall screws 12″ o.c. at floor and ceiling runners and intermediate studs. Fire side horizontal panel joints were offset from cold side horizontal panel joints by 24″. Fasteners were placed approximately 3″ in from framing corners and approximately ⅜″ in from panel edges.
- Framing members in fire-rated wall assemblies are cut ¾″ shorter than full height of wall thereby creating a floating frame wall. In order to transport these walls from the fire test facility to the sound test facility, fasteners were placed through the wall panels into framing members at floor and ceiling runner tracks to provide racking resistance to facilitate specimens handling. This modification does not change the sound transmission characteristics of the wall assembly.
- Joints were treated with chemically-setting powder gypsum joint compound (USG® Durabond® 90), complying with ASTM Specification C 475, for flush joining the panel edges. Setting-type compound was mixed in accordance with manufacturer's written instructions. Compound was applied to fastener heads and joint recess was formed by adjoining sheets. Perforated paper reinforcing tape was immediately imbedded centrally into the joints. Perforated paper reinforcing tape was immediately imbedded with additional compound and allowed to dry.
- The ambient temperature at the start of the test was 80° F., with a relative humidity of 84%. Throughout the fire test, the pressure differential between the inside of the furnace (measured at a point ⅓ of the way down from the top center of the wall specimen) and the laboratory ambient air was maintained at −0.03 inches of water column, which resulted in a neutral pressure at the top of the test article.
- Observations made during the test were as follows:

Hose The wall was exposed to the standard hose stream test Stream for at a pressure of 30 psi from 20 feet away from the exposed surface for a period of 60 seconds. The test article failed the hose stream test when the hose stream penetrated the wall after 19 seconds. - During the fire test, the wall was measured for deflection at three points along its vertical centerline: at 30″ (position #1), 60″ (position #2) and 90″ (position #3) from the left side of the wall. Measurements were made from a taut string to the wall surface at each location.

Hose The wall was exposed to the standard hose stream test Stream for 60 seconds at a pressure of 30 psi from 20 feet away from the exposed surface. The test article withstood the hose stream test without allowing passage of water through the wall.
Conclusions from Fire Testing - The 20 GA., 3⅝″ galvanized steel stud wall with Applicant's laminated composite panels (⅛″ thick Hardiboard® fiber-cement face skin laminated to ½″ thick Hardirock® “Max C”™ gypsum wallboard) on both surfaces, constructed and tested as described in this report, achieved a non-loadbearing fire resistance rating of 60 minutes for a symmetrical wall assembly according to the ASTM E119 standard.
- Summary of Advantages
- The preferred embodiments of the present invention combine fire resistance of at least 1 hour and significant abuse and impact resistance in a prefabricated single piece laminate composite comprising fiber-cement laminated to gypsum. These properties are achieved in a laminate composite which in one embodiment is only about ⅝″ thick that is not excessively heavy, is easy to cut and is quick and easy to install.
- One disadvantage of the two layer systems of the prior art is that the individual pieces of fiber-cement and gypsum must be self-supporting in order to facilitate their individual installation. The layers of fiber-cement and gypsum, therefore, are limited in how thin they can be in order to remain self-supporting. The preferred embodiments of the present invention, however, combine the fiber-cement and gypsum layers into a prefabricated single piece laminate composite for installation. Thus, the individuals layers of fiber-cement and gypsum need not be self-supporting, and the thickness of the fiber-cement layer, for instance, can be significantly reduced. This reduces the overall thickness of the single piece laminate composite as compared to the two piece systems. As a result, one embodiment of the present invention incorporates a ⅛″ fiber-cement layer and a ½″ gypsum layer to create a single piece laminate composite about ⅝″ thick, that simultaneously achieves a one hour fire resistance rating and abuse and impact resistance.
- The embodiments illustrated and described above are provided merely as examples of certain preferred embodiments of the present invention. Various changes and modifications can be made from the embodiments presented herein by those skilled in the art without departing from the spirit and scope of the invention.
