Abstract
A double-glazed, light-transmitting panel having a pair of plastic face sheets permanently bonded to and spaced by a mechanically interlocked I-beam grid core. The grid core employs an I-beam spacer attachment which comprises a plurality of I-beams each having a pair of identical flanges joined by an interconnecting web with each of the flanges being formed with a dovetail keyway, a plastic connector seated upon each I-beam flange and having a dovetail tongue engaging a mating dovetail keyway, and an adhesive layer bonding each face sheet to opposing connectors separated by the I-beams. An alternative embodiment for the plastic connector has a generally U-shaped cross section that snaps on the flange of the channel. A method for fabricating a plastic connector by using the I-beam flange as a mold is also disclosed.
