Can I use silicone to seal SunGlaze?

Silicone sealers and adhesives can be used if they are the neutral cure type, also check with the manufacturer if they are compatible with polycarbonate plastics.

What should I use to clean my panels?

Warm water with a mild household detergent should be sufficient to clean SunGlaze sheets. Wipe off any remained dirt with a soft cloth and wash again.

AVOID using sponges or brushes that can scratch the sheets surface.

Unique to SunGlaze is the inclusion of dual surface UV2 protection making SunGlaze ideal for installations over pool and spa area – providing maximum protection for your family and friends while using your outdoor area.

Our sheets have a twin surface UV protection, therefor both sides offer the UV blocking benefits

Personal choice.
The SunGlaze Base will cover the rafter. If using purlins, we suggest that the topside of the purlin is painted a light colour to avoid heat build-up. Please note the SunGlaze Base is 65 mm wide.
