Abstract
Sandwich panels comprising two sheets of polymethylmethacrylate (PMMA) enclosing a translucent core layer of closed cell foamed or expanded resin. The edges of the panels are enclosed by profile strips, which allow the panels to be mounted in a supporting framework to build a flat or curved canopy. The panels are used for mfr. of domed or vaulted roofs transmitting diffused light. Composite structure is stiffer and stronger than corresponding structures with a void between twin layers of PMMA glazing, is better able to resist snow loadings or wind pressure.
