What are the different types of roof windows?

There are three key types of roof window available on the market. These are:

  • Top-hung roof windows
  • Side-hung roof windows
  • Centre-pivot roof windows

We stock all these and more at Toughened Glass Systems, so view our collection above.

Do you lose heat from a roof window?

Roof windows are designed to be thermally efficient, through a process called ‘thermal breaking’. This refers to the way in which roof windows are sealed, using materials with a low thermal conductivity, and as such can work to trap heat within your room for longer.

Do roof windows break easily?

Typically, roof windows are made of double glazing, which will offer more protection than a single glazed window. They are manufactured with safety glass and generally situated on an area of the building that is less likely to be subject to impacts that may cause breakages, such as stones and debris kicked up by vehicles. 

Can I Install a Roof Window Without Planning Permission?

Roof windows installations generally fall under ‘permitted development rights’ in the UK, meaning you will not need to seek express permission to have a new roof window installed on your property.

If your building has protected qualities, such as being a heritage site or a listed building, then you may require specific permission from your local council to make adjustments. For roof window installations on these types of buildings, you may need to consider a conservation rooflight installation.

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.

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.
