The 8mm (5/16 inch) Polycarbonate Sheet offers superior insulation and versatility, making it a preferred choice for greenhouses, outdoor structures, and patio covers. With TwinWall technology, air channels between the walls help maintain warmer temperatures, reducing energy costs and protecting your plants in cooler weather.

Choose among three shades for different effects:

• Clear: Provides high light transmission and clarity.
• PoliSoft Diffused: Creates gentle, scattered light that reduces glare and provides an ideal growing environment, especially in high-sun areas (such as the southern USA or high elevations). Only available in 8mm thickness.
• 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: PoliSoft Diffused and Bronze options reduce condensation build-up, ideal for high-humidity areas like greenhouses and covered patios.
