The 25mm (1") Triple Wall Polycarbonate Sheet offers exceptional insulation, rigidity, and visibility. With its 3-wall structure and 1" thickness, this sheet is designed for strength and stability in various climates. The wide 3/4" channels enhance light transmission and provide a clear view, while the impressive R-value of 2.491 keeps spaces warmer and more energy-efficient.

Why Choose the 25mm Triple Wall?
The added thickness not only improves insulation but also boosts rigidity, making the 25mm Triple Wall ideal for installations that demand resilience and clear visibility. Available in Clear for maximum transparency or Opal for diffused, glare-reducing light, this panel works well in greenhouses, sunrooms, and other settings where insulation, strength, and light are priorities.

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).

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.
