What is Twinwall Polycarbonate?

Twinwall polycarbonate features a revolutionary twin-channel structure with an air gap between two protective layers. This innovative design provides superior insulation while maintaining exceptional light transmission, making it the ideal choice for greenhouse construction.

The twin-channel design evolved as the industry standard for greenhouse glazing because it perfectly balances light transmission (up to 90%), insulation properties, and durability. Twinwall polycarbonate has become the material of choice for professional greenhouse builders and serious gardeners.
