The 10mm (⅜ inch) TwinWall Polycarbonate Sheet is crafted for projects that demand extra strength, insulation, and durability. With enhanced insulation and rigidity compared to 6mm and 8mm sheets, this thicker panel performs well in demanding environments and supports wider rafter spans. TwinWall technology traps air between the walls, creating an insulating layer that helps maintain warmth, conserve energy, and protect plants during cooler weather.

Choose among three shades for different effects:

  • Clear: Provides high light transmission and clarity.
  • Opal: Creates diffused, glare-reducing light, perfect for roof applications, especially in high-sun areas (such as the southern USA or high elevations).
  • Bronze: Perfect for an attractive, shaded effect that provides added privacy and reduced glare.

Heat Savings: The Twinwall design with internal channels traps air, providing an insulating layer that helps maintain stable temperatures and reduces heating costs.

UV Protection: All colors are UV-protected on one side to resist yellowing and damage from prolonged sun exposure. 

Condensation Reduction: Opal and Bronze options reduce condensation build-up, ideal for high-humidity areas like greenhouses and covered patios.

Installation Tips:

  • Install panels with the flutes (channels) running vertically to maximize strength. End caps or vented tape are recommended to allow moisture to escape while protecting against condensation.
  • One side of the polycarbonate sheet has a UV-resistant coating. The printed or Blue side is the UV-resistant side. Be sure to install sheet with this side facing the sun to receive benefits and keep panel from yellowing.
