  • How to Measure for a Flat Rooflight

    With thermally efficient glazing (U-values as low as 0.7 W/m²K), Argon gas-filled units, and warm edge spacer bars, this rooflight keeps your home insulated all year round — helping to reduce energy bills.

  • Maximum Natural Light

    Enjoy uninterrupted daylight from every angle. This frameless rooflight maximises light entry, brightening your living space and enhancing the feeling of openness.

  • Sleek, Minimalist Design

    The Infinity Frameless Flat Rooflight features a striking all-glass design with no visible frame when viewed from inside your home. Its seamless, flush-fit aesthetic delivers a truly contemporary look, perfect for modern extensions and minimalist interiors.
