Simple Installation
Our fixed rooflight range has been designed with simple installation in mind and each unit is supplied pre-glazed ready for installation. Due to the high specification of the glass, considerations must be made on how to safely lift your rooflight.
For great ease our upstands are designed to make your rooflight installation hassle-free, regardless of the roof pitch or type. Choose from our flat upstands, ideal for roofs with shallow pitches ranging from 5 to 15 degrees, or our sloped upstands, which facilitate water runoff on flat roofs. Additionally, we offer two height options, 150mm or 300mm, specifically designed for warm roofs with insulation build-up of up to 150mm. With EOS upstands, achieving compliance has never been easier or more efficient. Simplify your project by choosing our versatile upstands today.
