A composite glass and molded frame member. In a specific embodiment, one or more glass panels may be utilized in association with a generally U-shaped elastomeric packing and mold-piece seal strip with thin leg portions engaging the glass. The strip has a collapse or compression zone formed outboard

A composite glass and molded frame member. In a specific embodiment, one or more glass panels may be utilized in association with a generally U-shaped elastomeric packing and mold-piece seal strip with thin leg portions engaging the glass. The strip has a collapse or compression zone formed outboard and adjacent the edge portion of the glass to accommodate, inter alia, differing thermal expansions and contractions of the glass and the frame. The glass edge and strip are unitary with a perimeter frame of urethane plastic material which is molded over the glass edge and seal. The mold pieces of the molding apparatus have continuous raised or ridge portions adapted to engage the leg portions of the elastomeric strip on either side of the glass panel to prevent flow of plastic material over the glass surface area encircled by the ridge portions of the mold pieces.
