Mardome Flat Glass Rooflight

Combining the ultimate in contemporary styling with exceptional thermal performance and regulatory compliance, Mardome Glass sets the standard in glass rooflights.  Featuring a thermally efficient double-glazed glass unit framed by a silver anodised aluminium frame, this ultra-modern flat glass design allows natural daylight to flood into buildings for light, bright and inviting internal spaces. Developed for flat and low pitched roofs of less than 15° this rooflight has been imaginatively designed to offer the widest flexibility possible with a choice of powered opening, ventilation, kerb and fixing options to ease the specification process.
