Abstract
"Narrow" Flush Glazed Thermal Framing"
Abstract The invention provides a thermal break configuration in a flush glazed, two-piece mullion which permits a reduced face dimension without reducing the depth of the glazing channels of the mullion. The invention is directed to a thermal break segmented filler assembly for the shallow glazing pocket in narrow flush glazed two-piece framing for curtainwalls, storefronts, and a like. The two-piece mullions have a major portion and a filler portion, of which are extruded profiles.
The filler assembly incorporates a thin thermal break which makes it possible to reduce the mullion face dimension and still provide a glazing pocket depth equal to that of conventional flush glazed thermal framing. The thin thermal break of the filler assembly includes a plastic channel extrusion having rigid upturned legs with relatively soft barbs which engage channels in aluminum extrusion ion filler halves. The thermal break filler element is snap fit onto and between the filler halves to form a three-piece filler assembly.

At an intermediate level in dle f~aIning struchlre, an intermedia~e horizon~al mullion 75 is indi ate.d which is a two-piece mullion having as its ~or part a face insert 71. The glass panel 36 rests on a setter block 82 along ~e horizontal interrnediate mullion 75 and is secured by ~e face member 71 WhiGh iS snap ~It onto the exterior upper side of in~e~nediate mullio~ 75 and which urges ~e glazing gasl~ets 42 against ~e glass panel 36.

The ~iller base 44 is geIlerally channel shaped in cross section and having press ~lt s pr~trusions 45 along its legs which are press fit into reciprocal pockets in ~e lateral comporlents 46 of ~e ~Iller assembly 43.
The press fi~ protrusions 45 are fle~i~e PVC and are coe~truded widl the ~lller base 43. The lateral memb~r~ 46 of the ~Iller as~embly include glazing gasket pockets 41 and a snap-0 erlgagement elip 48 ~or sec~g the filler assembly onto lockingflanges 50 i~ the ver~cal mullion 30. The lateral members 46 are e~truded aluminum similar to the extruded aluminum mullion~ e overall lateral d~ension of ~e ~lller a~sembly is representatively about 3.5 inch~s, relative to a mllllion depdl OI
S about 4.5 inches.
The ~hallow glazing posket filler assembly 43 permits a minimum sight line of the vertical mullioIls 30, repres~ntatively ~bout 2 inches, iD that ~e lateral facial dLmension of ~e mullion is reduced by eliminating a pour-20 debridge ~ermal br~ak in ~e S~llGW g~ ;lg pockct.

gla~g pocket 72 with a pour-debridge thermal break 68. A
dual pan~ glass parlel 36 is situated ~ ~e glazing channel 72 by means of gla~ing gaskets 40 ~nd 42 extending along the perimeter of ~e glass panel 36.
At an intermediate level in dle f~aIning struchlre, an intermedia~e horizon~al mullion 75 is indi ate.d which is a two-piece mullion having as its ~or part a face insert 71. The glass panel 36 rests on a setter block 82 along ~e horizontal interrnediate mullion 75 and is secured by ~e face member 71 WhiGh iS snap ~It onto the exterior upper side of in~e~nediate mullio~ 75 and which urges ~e glazing gasl~ets 42 against ~e glass panel 36. The intermediate hori~ontal mullion 75 is secured to the vertical mullion 30 with screws 76 pass~g ~rough ~e vertical mullion andl ~ d ~to splines 78 which are 3 integral with ~e horizontal n~ullion.
At the bot~om of the fram~g as~embly) the ~ooter horizontal m~on 86 is sea~d in a sill member 84 which ~ests on th~ floor 52 YVi~ a sh~n 54 inteIposed and having finishing lines 56 of ca~g. The sill mem~er B4 has a pour-debtidge ~ennal br~ak 85. The footer mullion 86 is substan~ially similar to a honzQntal intermedia~e mullion and is secu~ed to the ver~ieal mullion 30 ~ screws 76 passing ~rough ~e ve~cal mullion and tu~ned into splines 78 which are integral wi~ ~e ho rizo~tal sill mllllion. T~ footer mullion 86 includes a pour-deb~idge thermal b~eak g4. A gla~s paneï ~6 rest~ on a se~ter bloclc 92 along ~he footer mullion 86 and is secu~d Lrl place by a face member 87 beiDg snap fit o~to dle ~ooter muL1ion 86 which in tu~n urges ~e glazing ~askets 42 against ~e ~ss pa~el 36.
