WHY CHOOSE TWIN WALL POLYCARBONATE?

1. Superior Thermal Insulation: Air channels between the two layers create excellent insulation properties, keeping spaces cooler in summer and warmer in winter—ideal for greenhouses and pool enclosures.
2. Incredibly Lightweight: 10mm twin wall weighs only 1.7kg/m² compared to 12kg/m² for solid polycarbonate and 24.93kg/m² for glass. Easier to handle, transport, and install with less structural support required.
3. Exceptional Rigidity: The unique dual-layer structure with internal ribs provides superior rigidity and strength. Can span larger distances without sagging—perfect for pergola roofing and large skylights.
4. Diffused Light Transmission: 85% light transmission with natural diffusion eliminates harsh glare and hot spots. Perfect for protecting plants in greenhouses and creating comfortable outdoor living spaces.
5. Cost-Effective: Uses significantly less material per square metre than solid polycarbonate, making it 40-60% more affordable while still delivering excellent performance.
6. UV Protected: Premium UV coating on both sides blocks harmful UV rays, preventing yellowing and degradation. Suitable for Australian outdoor conditions.
7. Impact Resistant: Polycarbonate is virtually unbreakable—200x stronger than glass. Withstands hail, falling branches, and impacts without shattering.
8. Weather Resistant: Performs excellently in Melbourne's variable weather including intense sun, heavy rain, hail, and temperature fluctuations.

EXPERT INSTALLATION TIPS

Critical Installation Requirements:

1. Always Use End Closures: Seal the top and bottom edges with U-profile end closures to prevent dust, insects, and moisture entering the flutes.
2. Apply Breather Tape First: Install polycarbonate sealing tape on sheet edges before fitting end closures—this allows moisture to escape while filtering dust.
3. Correct Orientation: Install sheets with UV-protected side facing up (check protective film labeling). Flutes must run vertically to allow water drainage.
4. Allow for Expansion: Polycarbonate expands and contracts with temperature. Leave 3-5mm expansion gaps and use oversized screw holes.
5. Use Proper Fixings: Only use polycarbonate roofing screws with sealing washers. Never over-tighten—this can crack the sheets.
6. Support Spacing: For 10mm twin wall, support battens should be maximum 600mm apart for roofing applications.
7. Seal Joins Properly: Use aluminium H-joiners with integrated sealing for watertight joins. Plastic H-joiners require additional silicone sealing.
