Abstract: In a door constructed of spaced apart skins mounted on a rectangular frame and reinforced with the core between the skins filled with a plastic foam, a window or door light frame system consists of a two part frame system with a window light permanently installed in one part of the system and the other part releasably adapted to register with the frame part with the window light installed during shipping and rotated when installed to bring the locking elements of the several parts into registry to permanently lock the frame system in an aperture formed in a door with stop means in the locking arrangements to prevent damage to the frame system or the door on which the frame system is installed from excessive compressive forces on the frame parts.

Abstract: The present invention provides for an apparatus and method for applying adhesive to the end seals and/or the side glass surface of an insulating glass (IG) window unit to be mounted in a frame or sash. An apparatus and method of using the apparatus is provided by which adhesive is applied to the end regions of the insulating glass unit with one or more nozzles while a separate side arm extends from the device and alongside the insulating glass unit having a nozzle that delivers adhesive bead to the side of the pane to be adhered to the frame or sash.

Abstract: A sealed double glazing unit having an outer pane with a countersunk hole punched in a corner thereof, and an inner pane with a hole punched in a corner thereof, opposed to the countersunk hole in the outer pane. A generally cylindrical liner is inserted into the countersunk hole in the outer pane, a bottom of the liner extending into, without passing through, the countersunk hole in the outer pane. A glazing unit is secured to a supporting member by a fixing member which is fixed through the liner, and a sealing member engages the holes in the inner and outer panes. This sealing member includes a guide ring having the same diameter as the diameter of the bottom of the liner, with a front end of the guide ring extending into the countersunk hole and abutting against the bottom of the liner.

Abstract: A heat-insulating wall has two spaced-apart, at least essentially vacuum-tight cover layers, between which an evacuable heat-insulation material is provided and which are connected to one another by a vacuum-tight connecting profile which runs along the free edges of the cover layers. The connecting profile has a membrane which spans at least essentially the distance between the cover layers. The connecting profile is made up of a plurality of profile sections adjoining one another in a vacuum-tight manner. At the adjoining ends of the profile sections, the membrane has an end section with a thickness of at least approximately the material thickness of the cover layers.

Abstract: A multipane window unit is provided in which a sash frame is formed having an integral spacing structure upon which glazing panes are directly affixed. The spacing structure is formed integrally with the sash frame at internal glazing surfaces. Adhesive can be affixed to the internal glazing surfaces to attach the glazing panes. In this manner, a rigid, structural sash frame can be formed prior to attachment of the glazing panes, thereby eliminating the need for using separately manufactured insulating glass units while obtaining similar and improved benefits.

Abstract: An insulation panel (1) for cabinets containing air handling equipment has an exterior housing section (2) and an interior housing section (3) which is joined to the exterior housing section by snap-in engagement means, preferably comprising a plurality of tabs (12) provided on the interior housing section. The tabs engage a flange (6) of the first housing section (2) via a first gasket (13), and a circumferential side wall (10) of the second housing section (3) abuts against the first housing section (2) via a resilient second gasket (14), whereby the tabs (12) abut against said first gasket under some pressure to firmly secure the first and second housing sections to each other without creating any thermal bridges between the housing sections.

Abstract: A sealed insulating unit includes two parallel opposed panes with a spacing and sealing system between the two panes. The panes and the spacing and sealing system together define a sealed gas space. The spacing and sealing system includes a spacer frame with a primary seal between each side of the spacer frame and the opposing pane face and a secondary seal extending between the panes outside the outer peripheral face of the spacer frame. Each primary seal is greater than 0.4 mm thick on construction of the unit and has at least 7 grams of sealant material on each side of the spacer frame per meter of the spacer frame length. A spacer for a sealed insulating unit has side walls in which are defined elongate recesses, the dimensions of the recesses being selected such that sufficient primary sealant can be accommodated to provide in the sealed insulating unit opposed primary seals each at least 0.4 mm thick.

Abstract: A spacer profile for a spacer frame to be mounted in an insulating window unit by forming a space between the panes, with a chamber for receiving hygroscopic materials and with at least one contact web to lie against the inner side of a pane, which is connected via a bridge section with the chamber, is characterized i that the profile corpus of the spacer profile consists of an elastically-plastically deformable material with poor heat conductivity, and that at least the contact webs are permanently materially connected with a plastically deformable reinforcement layer.

Abstract: Modular tenon and slot mortise building blocks include, for each building block: (a) hollow rectangular parallelepiped center block, (b) an outer siding member, (c) a first tenon member sandwiched between the center block and the siding member, (d) an inner facing member, and (e) a second tenon member sandwiched between the center block and the facing member. The tenon members are parallel and mounted to longitudinal sides of the center block. The tenon members are positioned and of a length so as to extend longitudinally of a first end of the center block by a first distance and so as to form mortised first and second recesses having a first depth behind the first and second tenon members, respectively, between the siding member and the center block and between the facing member and the center block. The first distance is substantially equal to the first depth.

Abstract: A multipane window unit is provided in which a sash frame is formed having an integral spacing structure upon which glazing panes are directly affixed. The integrally spacing structure is formed integral with the sash frame at vertical internal glazing surfaces. Adhesive can be affixed to the vertical internal glazing surfaces the glazing panes. In this manner, a rigid, structural sash frame can be formed prior to attachment of the glazing panes, thereby eliminating the need for using separately manufactured insulating glass units while obtaining similar and improved benefits.

Abstract: A multi-sheet glazing unit includes a spacer frame having a pair of legs joined to a base to provide a U-shaped cross-section. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. A plurality of sheet retaining members in a spaced relationship to one another are maintained on the legs of the spacer frame between the glass sheets and spaced from the base. The sheet retaining members each have a groove for receiving edge of a sheet e.g. glass sheet to secure the sheet between the outer sheets. The sheet retaining member includes a first part having a vertical stop and a non-vertical platform e.g. horizontal platform and an elongated securing member detachably secured on the horizontal platform spaced from the vertical stop to form the groove. A method for making the unit is also disclosed.

Abstract: A lazing unit (1) comprises two sheets of glass (2,3) which are separated by a spacer bar (5). An outer secondary seal (10) extends around the periphery of the glazing unit. The seal (10) has a number of peripherally spaced-apart fixing inserts (50) extending around the periphery of the glazing unit for fixing the glazing unit support (17). Each fixing insert (50) has a base wall section (51), parallel side walls (52) and end wall sections (53) which define an arcuate slot (55) closed at both ends. The configuration of the fixing inserts (50) allows simple fitting while ensuring the maximum bulk of material for structural strength. Opposed fixing inserts (50) are engaged, on assembly, by a toggle (60).
