Measuring & Installation Guide

The size you will purchase for this range, is the same size as the structural opening in your roof. For example if your order is for an 800mm by 800mm polycarbonate dome rooflight, your structural opening will need to be built to 800mm by 800mm. When viewing from internally, your visible daylight size would be 600mm by 600mm which is due to the splayed upstand the unit is manufactured with.

The daylight size will be 200mm smaller than the Rooflight size as shown on the below sizing chart.

The roof structure with the upstand and rooflight installed is shown on the below diagram.

Great service from the team. Easy to order, good buying guidance and clear install instructions for my builder. Rooflights look absolutely great! The team at TGS couldn't have been more helpful in organising a smaller delivery vehicle to help with restricted access. Highly recommend TGS.

I was spending a lot of money on several rooflights so I wanted to make sure I got it right and I did. The professionalism, expertise and the quality of the roof lanterns really set Toughened Glass Systems apart.

The glass balustrade gives us an amazing view onto the lake outside. So happy we ended up going for the frameless glass balcony from Toughened Glass Systems instead of one with posts

My job is to design the interiors for a lot of houses and a lot of times the hardest part was when the client wanted some really inexpensive rooflights that should look like some contemporary ones as well. That until I found Toughened Glass Systems and started working with them more and more. They have a lot of this kind of stuff at a very decent price, a price for anyone I can say. If you’re looking for cheap skylights for flat roofs or any types of roof lights, they probably have something for you.
