Twinwall Polycarbonate Sheet — Complete Greenhouse & Roof Glazing Systems

Go Industrial supplies complete twinwall polycarbonate greenhouse and roof-glazing systems, including long-length panels, compatible installation components, cutting, project guidance, and local support. We help you order the right panels, in the right lengths, with every compatible component required to finish the project correctly.

Our 8mm twinwall polycarbonate sheet combines the characteristic strength of polycarbonate with excellent thermal insulation — making it the preferred choice for greenhouses, covered walkways, carports, skylights, and agricultural structures across Western Canada.

Key properties:

• Strong, lightweight, and virtually unbreakable
• Superior thermal insulation vs. single-wall sheet or glass
• UV-protected surface — resists yellowing and degradation
• High light transmission with diffused, even coverage
• Easy to cut, handle, and install on-site
• Impact resistant in cold Canadian climates

Common applications:

• Greenhouse glazing — commercial and hobby
• Patio and carport roofing
• Covered walkways and canopies
• Skylights and clerestory glazing
• Agricultural and barn cladding
• Pool enclosures and sunrooms

Available colours/finishes: Clear, Opal/White, Bronze

Complete your system: We stock compatible H channels, U profiles, end caps, sealing tape, and installation screws — everything needed to finish your project in one order.
