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.
