The reflective sheet is protected from intrusion of dust, fibers, etc. and faces a dead air space.
Description
- This application claims the benefit of co-pending
provisional application 60/345,770, filed Jan. 4, 2002. This is a continuation-in-part of: Ser. Nos. 10/039,101 filed Jan. 4, 2002, 10/056,730 filed Jan. 25, 2002, 10/103,636 filed Mar. 21, 2002, and 10/255,740 filed Sep. 26, 2002. - This invention concerns the heat insulation of building structures, particularly the use of heat reflective material alone or in combination with conductive and convective insulation.
- A typical prior art insulation placed in the ceiling and walls of a home or other building structure is fiberglass blanket insulation, which is rectangular in cross-section and cut to the desired length at the job site for placement between studs and joists of the building structure. In addition, a sheet of facing material is applied to one broad surface of the fiberglass blanket, with the facing material having overhanging edges extending beyond the sides of the blanket that can be applied to the studs, joists, etc. to hold the blanket in place. Typically, the fiberglass blanket would be placed in the space between the studs or joists, and the overhanging edges of the backing sheet would be stapled to the adjacent studs or joists.
- One of the most desirable materials for forming blanket insulation is fiberglass. Glass is a good heat insulator and the glass fibers trap a substantial amount of air between them to form a multitude of dead air spaces. This combination of glass fibers and trapped air provide insulation against convection and conduction heat transfer.
- The insulation blanket can be made of other fibrous materials such as mineral wool and cellulose, both of which provide a multitude of air spaces within the blanket. Also, the layer of fibrous material can be applied in other forms, such as in small masses of fiber glass, that can be blown into an attic.
- However, the fibrous blanket alone does not provide adequate insulation against radiant heat transfer. In order to provide the desired radiant heat insulation an additional sheet can be formed of reflective material, such as reflective aluminum foil, and applied over the blanket of fibrous material.
- One of the problems with the above noted structure that includes both the fibrous blanket and the reflective sheet is that when the reflective surface of the foil engages another surface, such as the fiberglass of the blanket or when the foil becomes dirty from the accumulation of dust, fibers, spider webs, and trash, the foil sheet loses its ability to reflect radiant heat. Therefore, when fiberglass blanket is combined with a reflective sheet material, care must be taken that the reflective foil is displaced from the other materials and that the reflective foil remains clean so as to retain its maximum reflective characteristics. It is this concept that this invention addresses.
- Briefly described, the present invention comprises a heat insulation blanket assembly for placement between elongated parallel support members of a building structure, such as joists of a ceiling or floor, or the studs of a wall. The heat insulation blanket assembly includes an elongated blanket, rectangular in cross-section, of convection and conduction heat insulation material, sized and shaped to fit between adjacent studs or joists of a typical building structure. A reflective sheet assembly is positioned in overlying relationship with respect to a broad surface of the blanket, of a length and breadth sufficient to overlie the length and breadth of the broad surface of the blanket and constructed so as to space the sheets from each other and to space the reflective sheet from the blanket and to form a dead air space therebetween.
- In one embodiment of the invention, the reflective sheet assembly includes a side foldable reflective sheet assembly that has a pair of overlying sheets, at least one of which is reflective. Foldable sides or gussets are formed on opposite sides of the assembly. The foldable sides each include a support flange at opposite edges of the blanket, with each flange having a proximal edge and a distal free edge, with the proximal edge attached to the comer of the blanket at the intersection of a broad surface with a narrow surface of the blanket. The reflective sheet material is attached at its edges to the flanges, intermediate the proximal and free edges of the flanges. The flanges are foldable about their proximal edges so as to allow the reflective sheet to be alternately positioned in abutment with the blanket or in spaced relationship with the blanket and forming a dead air space therebetween. The distal edge portions of the flanges protrude from the reflective sheet to form a connector strip extending beyond the reflective sheet for attachment to a support member such as a stud or joist of the building structure. With this arrangement, the reflective sheet can be moved into abutment with the blanket when the heat insulation blanket assembly is formed in a compact profile and into a reel configuration for shipment and storage.
- When the heat insulation blanket assembly with side foldable reflective sheet assembly is to be installed between the supports of a building structure, it is cut to length and the blanket is pushed in between the adjacent support members of the building, and the connector strips of the reflective sheet assembly are grasped by the installer and folded outwardly from positions parallel to the blanket to positions normal to the broad surface of the blanket, which places the connector strips parallel to and adjacent the support structures. This also functions to pivot the flanges outwardly and pull the reflective sheet away from the blanket, unfolding the side gussets and forming a dead air space between the reflective sheet and the blanket. The worker then fastens the connector strips with staples, fasteners, adhesive, or other conventional connector means to the adjacent support members, which holds the entire blanket assembly firmly in place in the building structure.
- In another embodiment of the invention, a compressible reflective sheet assembly is placed in overlying relationship with a broad surface of the fiberglass blanket. The compressible reflective sheet assembly includes a pair of overlying sheets, at least one of which is reflective, and compressible supports are positioned between the sheets. Typically, the compressible supports can be sponge material, with the sponge material formed in small shapes, such as one-half inch cubes with adhesive applied thereto. The adhesive would connect opposed surfaces of the compressible supports to both the sheets of the reflective sheet assembly, with the compressible supports being spread apart from one another approximately 1 foot. When the blanket assembly is compressed and formed into a reel for storage and shipment, the compressible supports are compressed between the sheets of the reflective sheet assembly to their minimum breadth so as to allow the blanket assembly to partially collapse and occupy the smallest practical shape. When the blanket assembly is taken in lengths from its reel, the compressible supports tend to urge the reflective sheet of the reflective sheet assembly away from the blanket, forming the dead air space between the reflective sheet and the blanket.
- When the compressible sheet assembly is to be oriented vertically, as when placed in a vertical wall, the compressible supports can be formed in the shapes of ribs that extend laterally across the blanket for the additional purpose of retarding vertical movement of air through the insulation blanket assembly. This reduces any tendency of convection heat transfer due to vertical air movement within the blanket assembly.
- The above described embodiments of the invention provide the combination of fiberglass or other blanket-type insulation against convection and conduction heat transfer, and a reflective sheet for insulation against radiant heat transfer, with the reflective sheet being spaced from the blanket insulation to form a clean dead air space that permits reflection of radiant heat by the reflective sheet material. Also, the dead air space between the reflective sheet material and the blanket insulation forms additional insulation against convection in the overall insulated structure.
- In another embodiment of the invention, boxes are provided in a shape compatible with the spacing between the joists and studs in a conventional building structure. Examples of the spacing between the joists and studs is16 inches from center to center of 2×4 inches studs or 2×8 inches joists, or 24 inches from center to center of the same sized joists or studs. The boxes can be formed with a length of approximately 22 inches and a width of 14 inches. This enables the installer to place the short dimension of the boxes between the 16 inch centered studs or place the longer dimension of the boxes between the 24 inches centered joists. The boxes are closed and have at least one internal wall that bears a heat reflective material for reflecting radiant heat. The boxes usually will be combined with fibrous insulation, such as blanket or blown fiberglass spread on top of the boxes or with the boxes resting on the fibrous insulation. The closed boxes also form internal dead air spaces that add convection and conduction insulation value to the structure and that prevent the dust, fibers, etc. from accumulating on the heat reflective surface of the internal wall of the box.
- Another form of the invention is the use of the side foldable reflective/expandable sheet assembly, or the compressible reflective sheet assembly, or the reflective boxes without the fibrous material attached thereto. These products can be used alone or can be combined at the job site with blanket insulation or loose insulation, for example.
- Thus, it is an object of this invention to provide an improved insulation assembly for building structures.
- Another object of the invention is to provide improved radiant heat insulation for building structures.
- Another object of this invention is to provide an improved insulation blanket assembly for building structures that is expedient to install and that provides reflective sheet material adjacent a dead air space.
- Another object of the invention is to provide an expandable reflective sheet assembly that can be used with or without additional insulation in a building structure and that forms an expandable unoccupied space adjacent the reflective sheet.

- Referring now in more detail to the drawings, in which like numerals indicated like parts throughout the several views, FIG. 1 discloses a side foldable
blanket insulation assembly 10 that includes ablanket 12 that is of approximately rectangular cross-sectional configuration, having opposedbroad surfaces narrow surfaces blanket 12 typically would be formed from spun fiberglass of conventional construction so as to provide entrapment of air between the glass fibers; however, other blanket material can be used if desired. - A side foldable
reflective sheet assembly 17 is adhered to thebroad surface 14 of the blanket. The assembly includes thereflective sheet 18, such as aluminum foil, and aparallel sheet 19, that can be either reflective or non-reflective. The reflective surfaces of the sheets face the interior of theassembly 17. Thesheets broad surface 14 of theblanket 12. Bothsheets broad surface 14 ofblanket 12, so as to completely span thebroad surface 14. - Foldable sides or
gussets 25 are formed between the edges ofsheets side flanges broad surface 14 andnarrow surfaces proximal edge 22 and a distal edge 24 (FIG. 1). Theproximal edge 22 of each side flange is attached to an edge ofsheet 19 at the adjacent comer of theblanket 12, and is pivotable as indicated byarrow 28. Thereflective sheet 18 is connected at its side edges to theside flanges connector strip 30 protruding beyond thereflective sheet 18. - When the side foldable
blanket insulation assembly 10 is in storage or in transport, typically theside flanges gussets 25 will be folded closed as indicated in FIG. 2 and as indicated at the right side of FIG. 1 by theside flange 21. When the blanket insulation assembly is received at the site where it is to be installed, theside flanges proximal edge 22 of the side flanges, so as to move from a position parallel to thebroad surface 14 of theblanket 12 to a position normal to thebroad surface 14. This forms adead air space 32 between thereflective sheet 18,sheet 19 and thebroad surface 14 of theblanket 12. Also, this places the connector strips 30 of the side flanges in the same planes of thenarrow surfaces blanket 12, so that the connector strips can be stapled, nailed, adhesively applied or otherwise connected with conventional connectors to the adjacent parallel supports 36 and 37 of the building structure. - As illustrated in FIG. 2, the side folded
blanket assembly 10 is placed by the installer between adjacentstructural members blanket 12 upwardly between the joists to a position slightly beyond the desired position, as indicated by arrow 38. The installer then grasps the connector strips 30 and unfolds them downwardly from their positions parallel to thebroad surface 14 of theblanket 12 to positions approximately normal to thebroad surface 14, as indicated byarrows blanket insulation assembly 10 in the direction as indicated byarrow 44. When the distal edges of the connector strips 30 are aligned with the lower edges of thejoists tool 39 or otherwise connect the connector strips 30 to the adjacent joist, stud, or other structural member (FIG. 4). This holds thereflective sheet 18 in its displaced relationship with respect to the adjacentbroad surface 14 of theblanket 12, creating the clean dead air space 32 (FIG. 5). - Once the
blanket insulation assembly 10 has been properly installed as illustrated in FIG. 5, another installer will installsheet rock 44 or other sheet material to the joists orstuds dead air space 46 between thesheet rock 44 and thereflective sheet 18. - If desired, the
sheet 19 can be or bear a reflective material, instead of or in addition to thesheet 18. Both sheets will face the dead air space between them and their reflective surfaces will be protected from accumulation of dust, fibers, etc. that would tend to occlude the reflectivity of their surfaces. - In FIGS. 6 and 7, another embodiment of the invention is illustrated that includes
blanket insulation assembly 50 that includes a blanket orbat 52 of insulation material and a compressiblereflective sheet assembly 53 having areflective sheet 54. The reflective surface of the sheet faces the blanket. Thereflective sheet 54 is maintained in spaced relationship with respect to theblanket 52 by means of a plurality ofcompressible spacers 56, such as cubes or other shaped sponges of approximately ½ inch in height, length and width. The cubes are coated with adhesive before being placed between thereflective sheet 54 andblanket 52 so as to adhere to the sheet and blanket and hold the sheet properly positioned in overlying relationship with respect to a broad surface of the blanket. This forms adead air space 58 between thereflective sheet 54 andblanket 52. The spacers are spaced from each other a distance that is effective to maintain the sheets in spaced relationship with each other and provide as much dead air space as practical, for example one foot apart. - When the compressible
blanket insulation assembly 50 is formed into areel 61 as shown in FIG. 6, thecompressible spacers 56 will be compressed so as to allow thereflective sheet 54 to at least partially collapse toward the adjacent broad surface ofblanket 52 so that the blanket insulation assembly occupies a minimum amount of space when in storage or transit. - When the compressible blanket insulation assembly is paid out from its
reel 61 and formed in a flat configuration, thecompressible spacers 56 andribs 60 will expand gradually so as to form thedead air spaces 58 as illustrated in FIG. 7. - FIGS. 8 and 9 show an embodiment of the invention that is similar to that of FIGS. 6 and 7, except that the
compressible spacers 56 that are in the shape such as cubes or other smaller objects are replaced withribs 60 that extend laterally across the elongated blanket and its reflective sheet. Theribs 60 form a barrier to air movement between the blanket and the reflective sheet. This is particularly useful for installing the insulation assembly of FIGS. 8 and 9 in vertical walls, where there is some tendency of air movement within the insulation structure. - As illustrated in FIG. 9, the
ribs 60 would extend horizontally between adjacentvertical studs 62. The ribs would function like thecompressible spacers 56, in that they are compressible for rolling the blanket insulation assembly into areel 62 and are expandable when the reel is paid out to form the dead air space between the reflective sheet and the blanket of fibrous insulation. - The embodiments of the invention of FIGS.6-9 are suitable for placement with the
reflective sheet 54 above the blanket, since thecompressible spacers 56 andribs 60 will oppose the gravity pull of thereflective sheet 54 toward contact with the adjacent surface of theblanket 52, so that thedead air space 58 is continuously maintained between the reflective sheet and the blanket. The installer can lay the blanket insulation assembly downwardly between the joists of a ceiling structure, against the sheet rock or other ceiling material with thereflective sheet 54 facing upwardly, with gravity holding the assembly in place. - It can be seen that the
side flanges side gussets 25 of the embodiment of the invention shown in FIGS. 1-5 and thecompressible spacers - The
reflective sheets - The insulation blanket assembly solves the two biggest problems with radiant barriers in building structures. For a radiant barrier to work with the low “e” the reflective surfaces must face an air space and the surfaces must remain uncorroded and dust-free for many years to be fully effective. The basic method used to fold out the facing layers of FIGS.1-5 can be done by: (1) pushing the insulation material a little too far in between the joists or other framing members, and (2) pulling outward on the connector strips to unfold the multi-layers. The connector strips are then stapled to the adjacent studs or joists.
- The embodiments of the invention as shown in FIGS.6-8 have a built-in self-deploying feature. When it is to be installed as an attic retrofit, the
insulation blanket assembly - While one-half inch cubes and ribs of sponge material have been disclosed as the compressible spacers, other kinds, shapes and configurations of spacers can be utilized, with the smaller sized spacers leaving more dead air space between the adjacent reflective sheet and the blanket. It is important to provide the maximum area of dead air space with nothing but dead air between the low “e” surfaces.
- FIG. 10 illustrates another use for the side foldable
reflective sheet assembly 17. Essentially the same side foldable sheet assemblies of FIGS. 1-5 are produced without blanket insulation being adhered thereto. The installer using a technique similar to that illustrated in FIGS. 2-5, places the side foldablereflective sheet assembly 17 between adjacent ones of thestructural supports structural supports reflective sheet 18 away from thecompanion sheet 19, leaving thedead air space 32. This provides the reflective sheet and its necessary dead air space between thestructural supports reflective sheet 18. Additionally, thedead air spaces - FIG. 11 shows essentially the same structure of FIG. 10, but further including
insulation 65 positioned on the side foldablereflective sheet assembly 17. The insulation can be loose insulation placed by hand or blown onto the upper surface of the side foldable reflective sheet assembly, or can be blanket insulation installed after the sheet assembly has been installed. - FIG. 12 illustrates the compressible
reflective sheet assembly 53 without the accompanying blanket insulation. Typically, the compressiblereflective sheet assembly 53 would be placed over loose orblanket insulation 65 that could be blown into position or positioned by hand between thestructural supports - FIG. 13 illustrates another way to install the compressible
reflective sheet assembly 53, that has its length extending across the lengths of thejoists - The arrangements of FIGS. 12 and 13 also can be constructed with the ribbed spaced product of FIGS. 8 and 9.
- With the arrangements of FIGS.10-13, it can be seen that the
reflective sheet assemblies - FIGS.14-17 illustrate the use of reflective heat insulator boxes used in a building structure for the purpose of providing reflective heat insulation.
- The boxes are placed between adjacent parallel joists or
studs bottom wall 74, atop wall 75,side walls box 70. - The bottom wall, top wall and opposed side walls all have interior surfaces that face the interior of the box when it is in its expanded configuration. The box defines an interior space that functions to contain dead air. At least one of the interior surfaces of the
bottom wall 74 ortop wall 75 bears a heat reflective material, such as aluminum foil. The reflective surface of the sheet material faces the dead air space within thebox 70. If desired, more or all interior surfaces of the walls of thebox 70 can bear the radiant heat reflective material. - It is desirable to have the boxes be substantially air tight so as to avoid the intrusion of dust, fibers, spiders, etc., thereby retaining the maximum reflectivity of the heat reflective surfaces. Accordingly, the ends of the boxes are formed with the end flaps and side flaps78-81 that can be folded to closed positions. Typically, the side flaps 80 and 81 would be folded inwardly as indicated by their direction arrows, while the end flaps 78 and 79 would be folded over the side flaps 80 and 81.
Adhesive tape 83 can be applied to the corners of the flaps, and a longer length ofadhesive tape 84 applied to the seam between the end flaps 78 and 79. This tends to substantially seal the box into a closed configuration, assuring that the intrusion of dust, etc. into the box is minimized. - As illustrated in FIG. 17, it is desirable to manufacture the
boxes 70 so that they are compatible with the spaces formed between the studs and joists of typical construction. The typical spacing between studs and joists is either 16 inches from center to center or 24 inches from center to center. In order to be compatible with this spacing of the rectilinear structural supports, theboxes 70 are formed so that they have a width that is compatible with the 16 inch center-to-center spacing and a length that is compatible with the 24 inch center to center spacing. In order to accommodate the width of the joists, studs, etc., the width of the boxes is 14 inches, which is compatible with the 16 inch spacing of the structural supports, and the length of the boxes is 22 inches, which is compatible with the 24 inch spacing of the structural supports. With these dimensions, the boxes can be used for either of the conventional spacings of the structural supports. - The thickness of the
boxes 70 should be great enough to have at least ½ inch interior spacing between the reflective surface of the heat reflective material and the opposed top or bottom wall. - When the boxes are manufactured and stacked for shipment, they can be in the conventional collapsed configuration where the
side walls tape 84, as illustrated in FIG. 16. - FIG. 18 illustrates an
insulation box assembly 90 that includes theexterior box 92 and the interiorinflated bag 94. The box is of conventional shape, in that it includes opposed parallel bottom andtop walls side walls opposed end walls end walls top walls end walls 100 folded as is illustrated in FIGS. 18 and 19. - The
bag 94 is inflated with gas, usually dry air. The bag bears a radiant heat reflective material that reflects radiant heat. A dead air space is formed in the bag when the bag is placed within the box and inflated. The reflective material of the bag faces thedead air space 95, so that the box and its bag protect the reflective material from being occluded by dust, fibers, spider webs, or other intrusion items. - The gas in the
dead air space 95 expands the bag to the shapes indicated in FIGS. 18 and 19, so that the bag tends to support the opposed bottom andtop walls bag 94. - While a specific construction of the ends of the boxes has been illustrated in the drawings, it will be understood that various other closure configurations can be formed at the ends of the boxes to expedite the box erection procedure.
- Although preferred embodiments of the invention have been disclosed in detail herein, it will be obvious to those skilled in the art that variations and modifications of the disclosed embodiment can be made without departing from the spirit and scope of the invention as set forth in the following claims.
