I am the owner of Top loft company ltd, after reviewing reviews from various companies I ordered 2 juliet balconies from tgs arrived within 3 weeks, comunications and help was brilliant.
Thanks for all your help.
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.
Great service from a very knowledgeable company. Thanks team Toughened Glass Systems.
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.
There are no complaints about the experience with TGS. The entire process of ordering, supplying and delivering was flawless. I would really recommend you order your flat roof sky lanterns from these guys.
Best place for rooflights, they supply many different types and options. Thanks for all your support Toughened Glass Systems!
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.
Always kept us up to date with our order even when delayed by a few days. Great service from the start and good quality glass balcony delivered.
