Wonderglas GCP translucent sheeting is so good, and so far ahead it has a Lifetime Warranty. Until now, domestic polyester sheeting has not had the exceptional surface protection offered by the latest surface coating technology. Wonderglas GCP is also heavier in weight at 1500 gms so it allows longer spans. Another big benefit is its relatively high shade factor, while providing plenty of soft, even light, it is much cooler below than transparent sheeting. Wonderglas GCP is also 99% UV safe.
Planning: Wonderglas GCP sheeting resists scratching, is light, easily drilled or sawn and quickly fixed to roofing timbers using Ampelite screws and sealing washers. Sheets can be curved, so you can create a great look.
Correct Installation is important: Wonderglas GCP is fixed and flashed on similar principles as steel roofing. Minimum fall is 5 degrees. Start by fixing the first sheet at the end farthermost from the usual wind direction. If end laps are necessary, start at the bottom corner.
Wonderglas GCP Corrugated sheets should be crest fixed at every second or third corrugation at the ends and every third or fourth corrugation on intermediate supports. Always use Ampelite fixing screws and weather seals.
Wonderglas GCP 5 Rib sheets should be crest fixed on each rib at the end of every second rib on intermediate supports
Long lengths (up to 8.0 meters) are available, but if joining two or more sheets lengthwise, the joins should be made over a batten or purlin, with a 150mm overlap.
