Ondalite, a new multi-wall polycarbonate roofing panel product, is available from CO-EX Corp. The panel is produced in both 3 mm twin wall and 6 mm triple wall sheet which incorporate a pre-shaped waved structure. Ondalite has an optimal combination of properties, including high load-bearing capacity, excellent thermal insulation, high light transmission and outdoor weatherability characteristics with a 10-year warranty against UV attack. Easy to install, Ondalite can be overlapped lengthwise to obtain large lighting surfaces. The channels of the panel are heat sealed at the ends, which preserves the aesthetic look of the sheet by keeping outside impurities out.
