Each U channel encloses a side of the bar. The resulting split metal longitudinal shell of the channel is made by casting the insulating bar within a C shaped metal channel shell and after the bar is hardened, cutting along the length of the channel completely through the C channel shell to the insulating material.
- It is one object of the invention to reduce thermal conduction across a metal channel that forms the spacer frame for mounting between glass panes of a thermal window.
- A spacer channel for a frame which separates window panes to form an insulated window has a plurality of openings spaced from each other along the length of a straight portion of the channel. The openings are through a wall of the channel that faces outward along the periphery of the frame and glass sandwich when the frame is between panes of glass. The openings are designed to prevent significant passage of sealant from the outside of the channel to the inside of the channel through the openings. This is done by (a) the cross sectional area of each opening being so small that it resists viscous flow of the sealant through the opening, or by (b) a cover over the opening, or by (a)+(b).
- In an insulated window assembly comprising a first pane, a second pane, a spacer channel mounted between the first and second panes for separating the panes to form a channel and pane sandwich insulated window, the spacer comprises a first elongate wall facing the first pane, a second elongate wall facing the second pane, a third elongate wall connected to the first and second walls, facing outward along the periphery of the channel and pane sandwich, and a plurality of openings through the third elongate wall along the length of the third elongate wall.
- The total cross sectional area of the openings comprises 80 to 95 percent of the cross sectional area of the third elongate wall.
- In one arrangement the cross sectional size of each of the plurality of openings is small enough so that sealant cannot significantly enter the channel to the area between the first and second elongate walls by way of the openings.
- In another arrangement a low thermal conductivity strip covers the plurality of openings, and a sealant extends over the first, second and third elongate walls of the channel, covering the plurality of openings, and against the thermal conductivity strip.

It is also to be understood that the phraseology or terminology employed is for the purpose of description only and not of limitation.
- Referring to FIGS. 1, 2,4, and 5, strip metal is stamped and rolled to form C-
channel 20.Openings 22 are formed throughouter wall 56 which faces outward 24 along the periphery of the spacer frame andglass sandwich 34. This reduces the rate of heat transfer across 36outer wall 56, and therefore reduces the rate of heat transfer betweenglass panes 30 bychannel 20. - A
strip 44 of material having stiffness and low thermal conductivity such as a paper sheet or a plastic sheet is laid onwall 56 overopenings 22 insidechannel 20 so thatstrip 44 seals the openings. - Desiccant62 is installed within
channel 20.Strip 44 prevents passage of the desiccant out of the channel by way of coveredopenings 22. -
Semi-viscous sealant 50 is applied outside the channel toouter wall 56 andvertical walls 32.Strip 44 prevents passage ofsealant 50 into the channel by way of coveredopenings 22. -
Strip 44 is fastened towall 56 insidechannel 20 by adhesive 66. The adhesive is of high strength to resist force from semi-viscous sealant that is applied to the outside of the channel to separate the strip fromwall 56 by pushing thestrip 44 away fromwall 56 inward into the channel as the sealant enters intoopenings 22. - The adhesive is also designed to survive the high temperature of sealant as it is applied on the channel, and to survive ambient temperature extremes that the completed window sandwich is likely to encounter. For example, hot melt butyl sealant can be applied at a high temperature of 250 degrees F. The adhesive is preferably designed to survive and stick from −20 degrees F. to 300 degrees F. and not to release gas or moisture into the channel that would contaminate the space between the panes of glass.
- Preferably the adhesive is designed to prevent passage of gas or liquid past the adhesive. The adhesive is also chemically compatible with the sealant so that it is not weakened by chemical constituents of the sealant.
- The adhesive can be applied to the
lateral borders 72 of the strip, so that the adhesive will not come into contact with the sealant at themiddle region 74 of the strip so that the sealant is in direct hermetically sealing contact with the strip. - The adhesive and strip are preferably impervious to gas and moisture transfer. If the sealant forms a moisture and gas seal over the openings after the sealant hardens, the strip does not have to be impervious to gas and moisture.
- The sealant can be applied after the adhesive cures. Suitable adhesives include pressure sensitive contact, air-cure, and epoxy materials.
- The strip can be paper, plastic, metal, or other material that meets the above performance descriptions.
- V-
cutout 38 is used to form a corner by folding ofwall 56. - The strip can be slightly elastic if it crosses
fold line 80 of the channel, so that the strip does not break when the corner is folded. - The strip can be cut or be discontinuous at the fold line to avoid tearing it when the channel is bent at the fold line to make a comer of the spacer frame.
- In FIGS. 3, 6, and7,
strip 44 is laid onwall 56 outsidechannel 20 overopenings 22 so that it seals the openings. -
Strip 44 prevents passage of the desiccant out of the channel by way of coveredopenings 22, and prevents passage ofsealant 50 into the channel by way ofopenings 22. - Preferably the openings comprise 80 to 95 percent of the cross sectional area of the outer wall of the straight portion of the channel, allowing for
bend margin 84 on each side offold line 80. - Preferably the openings do not have sharp corners, but are curved around the circumference so that viscous sealant will flow into contact with the entire edge of the circumference of the opening. The openings can be any shape.
- If the strip is not used to dam the hole against flow of the sealant through the hole into the channel, the holes are at least so small that the sealant cannot flow through the hole into the channel, that is, the sealant is not lost into the channel when it is applied to the outside of the channel. In that arrangement, the opening could be about {fraction (1/16)} inch in diameter for example, calculated according to the viscosity of the sealant.
- FIGS.8-10 show three different shapes of
openings outer walls - In FIG. 11, openings or
holes 98 ofchannel 100 are designed so that they are narrow enough to prevent significant flow ofviscous sealant 104 through eachhole 98 into the channel. - The sealant only wells upward into the hole, and may extend only slightly above the hole
inner opening 108, but not significantly into 110 the channel. - The invention comprises the outer wall of a window spacer frame, and is not meant to be limited by the shape of the rest of the frame stock.
- FIGS. 12 and 13 show two,112 and 118, of many frame stock cross sections that can contain the invention. Each of the two contains
openings 124. - In FIG. 14,
channel 20 is mounted betweenpanes edges corner 146 ofpane 130 andedges corner 148 ofpane 132.Semi-viscous butyl sealant 50 is shown between the panes and the channel, but is omitted from the drawing overoutward side 152 ofouter wall 56 of the channel for clarity of viewing.Butyl sealant 50 betweenelongate wall 32 ofchannel 20 andpane 130 seen throughpane 130 is shown in dashed lines. Lowthermal conductivity strip 44seals openings 22 against passage of sealant fromoutward side 152 throughopenings 22 into the space betweenvertical walls 32. - Although the present invention has been described with respect to details of certain embodiments thereof, it is not intended that such details be limitations upon the scope of the invention.
