Viva Skylights have big advantages, they are made to measure and available in 3 colours. This quick guide will give you an idea of how the skylight plinth will work in with your roof. To make sure the roof aperture is correctly constructed to the right size we produce a drawing for your builder upon receipt of deposit. Your builder will be responsible for constructing your upstand.
The upstand may then have a thickness of 85mm minimum and 100mm maximum. The upstand should be free from undulation and level.
In all instances the aperture should be square and you can check this measuring from corner to corner as our drawing shows. Both green arrows are the same measurement so the opening is square. Check the upstand is flat and level with a spirit level.
