Abstract: A window insulation system adapted for use on large metal or wood framed windows such as used in factories, schools, etc., is installed in spaced relation to a window sash on the side thereof facing the interior of a building. The system includes insulation panels which are mounted on and held in spaced relation to the window by a framework which is supported on brackets mounted on window mullions. Additional stabilization of the system may be provided by brackets which are mounted on window muntins. The framework includes horizontally disposed H-shaped runners with vertical spline members mounted thereon, the spline members having double flanges which are adapted to extend between adjacent edges of the insulation panels. Decorative single-flanged splines cover the space between adjacent panel edges on the building interior side thereof, the single flange extending between the panel edges and the double flanges of the double-flanged spline to removably secure the panels on the framework.

Abstract: The invention is directed to a clip structure for fastening a specific type of ceiling panel to a specific type of support structure. Both the support structure and ceiling panel have flanges and the clip spans the two flanges to fasten them together.

Abstract: A non-woven material is applied to the surface of a woven scrim. The non-woven material is needle-bonded to the scrim. The composite structure is then embossed. The embossed pattern is placed by a heated embosser on the finished product and in the non-embossed areas, the heat of embossing causes the non-woven material to partially melt and assume a textured effect which mirrors the texture of the woven scrim.

Abstract: A suspended ceiling is provided having a main grid assembly defining the lower plane of the suspended ceiling and having trusses connected to the grid assembly. A support frame is positioned above the lower main grid assembly defines the upper ceiling plane. Outrigger arms pivotally attached to the ceiling support frame are used to suspend the support frame from the trusses on the main grid assembly and to position the support frame relative to the main grid assembly. A ceiling board is mounted within the support frame and a plurality of ceiling boards are carried by the combination of the main grid assembly and the support frame.

Abstract: Suspended ceiling systems are formed from a series of modules which may have a vaulted design and a light fixture therein. These modules must be supported from the main runners or cross tees of a suspended ceiling system. The support structure herein is fastened at one end to the main runners or cross tees of the suspended ceiling system and carry on their other end the main horizontal support members for the light fixture and vaulted module.
