Combines endless design possibilities with many important advantages:

Polygal Standard Sheets double and triple layered, manufactured in various colors and degrees of transparency, are designed for use in most conventional roofing and glazing applications.

  • Excellent thermal insulation
  • Highly flexible, yet virtually unbreakable
  • Lightweight and easy to install
  • Rigid sheet structure provides extra strength under wind and snow loads. To see sheet performance under loads, go to “Support / Wind Load Charts”.

Standard Sheets feature a UV protective layer to protect against yellowing, and are covered by a 10 Year Warranty against breakage and yellowing (6 mm and higher).

Recommended Uses: Covering of medium span structures where excellent thermal insulation is required.
