Abstract

See full text

This invention relates to a curtainwall system having panels mounted on a grid formed of vertical and horizontal mullions having a planar or flat exterior surface. Each of the panels is provided with a frame formed of hanger sections having a groove facing the interior of the frame. A panel engaging clip has one end inserted in the groove of the hanger frame and the other portion of the clip secured to the grid. The clip urges the hanger against the weatherstripping of the grid to provide an air and dust tight seal. A polyurethane block is mounted in the space between adjacent panels and thereafter a silicone is extruded into the space.
