Heat reflective surface


The heat absorbing and reflecting properties of Topglass SPF 4 and SPF 8 is a direct result of the unique solar control compounds which are in turn added to the Gel-Coat Matrix. The product is specifically designed to reflect the heat away from the building whilst permitting the transmission of quality natural light. In colder climates, heat contained within the building will be retained for longer periods.


 

Operating Temperature

The operating temperature range of Topglass SPF is - 20° C to +95° C.


 

Warranty

Topglass SPF 4 and Topglass SPF 8 products are supported by a comprehensive 25 year warranty. Contact FGW Corporation Pty Ltd for full warranty details
