The 6mm (¼ inch) Twinwall Polycarbonate Sheet is a top choice for greenhouse coverings and pergolas, combining durability with impressive insulation benefits. Twinwall panels are designed with air channels that provide up to 50% energy savings compared to single-layer coverings. This innovative structure helps keep plants warmer, reducing heating costs during cooler months.

Each panel is lightweight yet rigid, making it easy to install and handle. Whether you're constructing a new greenhouse, upgrading existing glazing, or adding a stylish roof to a patio, these panels fit seamlessly with most aluminum and glass structures using standard glazing clips or bar caps.

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.
