Engineered and designed to be high quality and easy to install, this self supporting roof system is perfect for a wide range of applications including conservatory roofing, canopy roof and carports roofs. 

The system consists of self supporting glazing bars with dedicated main and end bars.

All available in a wide range of colours including White, Brown, Anthracite Grey, Black, Rosewood and Light Oak.
