FLAMMABILITY The resins used to make are specially developed for excellent flame retardant properties. INSULATION The twinwall profile gives effective heat-loss reductions when used. The following require caution: instead of regular glass. Savings of up to 50% have been documented. Insulation values Increase with thicker profiles, as noted in the Standards Table. STORAGE OF PANELS The sheets should be stacked on a solid flat surface. Store out of direct sun to avoid accumulated heat effects. Cover for protection. Never use flexible vinyl sheet as a cover as the plasticizers may react with the polycarbonate. CLEANING OF INSTALLED PANELS It is very important to use only warm soapy water for cleaning. Never use abrasive cleaners, solvents or sharp tools on the sheets. Always rinse well with clean water after washing. Wipe dry with a soft cloth to avoid water spotting in hard water areas. Contact the manufacturer for reference to specific cleaner brands. |
