Brett Martin Flat Glass is a premium flat glass rooflight intended for installation on flat roofs of all modern building types to provide natural light (and ventilation where specified).  The double-glazed glass panel is encased in a powder coated aluminium frame, providing a sleek product from every angle.

The skylights can be easily placed atop the existing builder's upstand or kerb. These skylights are manufactured in our manufacturing base in the United Kingdom.
