1200mm by 1200mm (120cm by 120cm) external dimensions, 1000mm by 1000mm (100cm by 100cm)) internal dimensions Frameless (simple and neat) Double glazed (reduce heat loss) Argon gas filled (for insulation) Self cleaning (for low maintenance as rain does most of the work) Clear 37Kg each (heavy and awkward to move) Pickup from Surbiton, London Two people are needed to lift and move each rooflight. Please be aware that these are glass, heavy, 120cm wide and therefore awkward to handle. Background - I bought four Frameless flat glass rooflights in 2022 (I incorrectly bought on the outside dimensions rather than the inside dimensions). The supplier would not accept a return for a larger size. They are unused other than being in storage for three years.
