How thick does your Roof Light Glass Need to Be?

When shopping around for the right roof light for your home, it is likely you will come across various measurements for the glass. Not every supplier will provide you with the optimum measurements as standard so never be afraid to ask questions. You don’t want to end up paying extra for what you can get elsewhere without an additional cost.

When it comes to installing skylights in your home, safety is paramount. The perfect product should be a blend of contemporary design, thermal efficiency, safety and security.

The glass used in manufacture is the best indicator for safety levels so it is essential that you choose the right kind of glass for your rooflight. In order to ensure your utmost safety, the ideal specification should include an outer toughened pane and an inner panel of heat strengthened laminated glass.

What is Toughened Glass

Otherwise known as tempered, toughened glass is specially treated to be far more resistant to breakage than standard glass. Toughened glass is ideal for the outer pane as it greatly reduces the chances of breakages. If smashed, it is made to shatter into multiple tiny fragments instead of larger more hazardous shards.

What is Laminate Glass

Laminated glass is commonly used for safety and security purposes, because rather than shattering on impact, it simply cracks. The interlayer, which helps hold the sheets together, greatly reduces the danger of sharp glass fragments, and increases the durability of the pane.

When located overhead an inner pane of laminated glass has the significant advantage over alternatives such as toughened glass, as if broken it will support itself and the glass pane above rather than shatter and fall in which could be dangerous..

Why We Choose to Always use Laminated Glass

Since our formation we choose to always use laminate glass where possible. The reason can be seen below as this viral video showed the problem with flat glass when flat is when broken the glass shatters completely losing its rigidity and will eventually come falling down. Although rare, it is a risk we prefer not to take for everyone safety.

What can go wrong with Toughened glass only…

Glass Units – What are my options?

Depending on the product, the structure and make up of the glass unit will be slightly different to suit its purpose, Please find below a brief explanation of some of the most popular configurations and remember if you would like any further advice please do not hesitate to contact us.

Double Glazed Rooflights

The type of glazing is also important to consider. The majority of products on the market are DGU (double glazed units) as single glazing would simply not do the job of keeping your home secure and keeping in the heat from your home.

In fixed and opening roof lights 4mm thick glass is just not sufficient and you should insist on 6mm in any glazed roofing product. The vast majority of roof lights on the market rely on 2 toughened glass panes, however at EOS, we feel a minimum outer pane of 8mm toughened and 8.8mm inner pane of laminated glass offers significant safety and security benefits.

If you would like more information on our double glazed fixed and opening units click here.

Triple Glazed Units

Depending on the product, the structure and make up of the glass will be slightly different to suit its purpose, On triple glazed units the glass unit will be made up of three panes with a cavity that is injected with Krypton or argon gas which significantly improves its energy efficiency.

Again, the outer pane should be toughened, and we strongly recommend a laminated inner one to reduce the chance of damage.

Our EOS97 Roof Lights feature a 32mm triple-glazed unit with an outer 8mm toughened pane, 6mm toughened glass in the middle and an upgraded 8.8mm laminated inner pane as standard.

Walk On Specifications

Walk On units should naturally have a thick outer pane in order to bear the necessary impact. At EOS, ours walk on roof lights come as standard with a 50mm double glazed unit, comprising of a 33mm toughened & heat strengthened laminated outer pane and 8.8 mm laminated low e inner pane.

EOS Rooflights were knowledgable in their field, very helpful and the products (Roof Lantern and Flat glass roof lights) were of a good quality. The Roof lights were easily installed and full installation instructions were supplied for those who are installing for the first time. Would recommend.

Very efficient with processing my order and delivery. I ordered a 3M roof lantern and a smaller flat roof light. Both were simple to install on my own upstands and they both look great. My only negative was the cost was a lot for what they are but I don’t think eos are excessively expensive, I think the roof lanterns themselves are what’s pricey. Anyhow I’m happy 😃

EOS were brilliant all through the consultation/sales process and delivery. The skylight looks great and works a treat with the electronic switch. Their after-care support was also very helpful and patient when we mistakenly thought we had an issue. Would highly recommend them.

As a company we have used EOS for some time. We use the EOS Rooflight Flexi Lid product a lot and also the EOS Smoke Vent Rooflight AOV on our projects. We cannot fault the company for the service, communication and value for money.

Excellent products, great customer service and post sales support! Unfortunately the courier damaged our roof lights slightly, however EOS went above and beyond to rectify! Special mention to Natalie O’Hara in ops, she was so helpful, prompt and a real pleasure to deal with! Highly recommend EOS!

The rooflights are a key feature externally of the property as they are prominent on the flat roof. They are angled by 15 degrees to allow the south facing sun to enter the house maximising natural light and also utilising any solar gain. The majority are triple glazed, with a couple of larger opening lights being double glazed. Internally they provide so much light and the light shafts are a characteristic of the internal architecture given that there are 15 within the house. The ordering and supply process was straightforward and installing them worked well with the pre-made upstands. All in all a very satisfactory and successful decision to select Eos rooflights.

I was after rooflights with laminated glass and of good quality! I contacted EOS after seeing and viewing their products. They fitted the requirements. The service was first rate, nothing was a problem and the drawings to work before delivery excellent. Would highly recommend.
