Flat Rooflight

Our Flat Rooflight system was the first system designed by First Glass Roofs, boasting large thermal breaks for unrivaled truly tested U-Values. Keeping a minimalist aluminium structure is always key to our designs, while also being very versatile in its design construction allowing triple glazed and quadruple glazed to be achieved yet remain flush with the frame, making this system one preferred by installers across the UK. 


Our Flat Rooflights should be pitched at 5 degrees as an industry standard to ensure minimal pooling on the Rooflight. We only use top specification glass in the manufacture of the flat rooflight for product safety and longevity.
