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.

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.

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..

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 Eco 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.

Delighted with our rooflights. EOS did everything they said they would do when they said they would do it. We were a bit nervous about doing our own fitting but we got precise, practical instruction diagrams and all went very smoothly

From ordering to receiving our rooflight everything went great, we built the upstand ourselves from the drawings supplied and the light fitted perfectly. Excellent product at a great price. Wish everything on our extension went that well. 5 stars all round.

Clearly a top quality roof light which is beautifully made. I looked at several manufacturers and the EOS had the best insulation among those I looked at. The frame is substantially made and the glass perfectly set into it. It was really simple to fit and the superb drawings allowed me to construct the kirb with confidence and accuracy. Delivery was fast and the unit well supported and protected on a pallet.

In the middle of Covid 19 lockdown they were able to advise, honestly estimating the future timing of delivery. I had to wait, which was not surprising, but their service was very personal.

Ordered my roof light well in advance of delivery date And it arrived on the pre arranged date. The item came with fantastic fitting instructions and requirements, a pleasure to fit. I’ll be recommending these products to future clients. Nice to see great design and ease of fitting with a sales and delivery service to back it up.

Quotation was prompt, the technical questions I asked were promptly replied to by the team and when the order was placed, I was kept updated with progression and delivery date. My non-standard delivery request (by hiab lorry to off load) was handled well and I would recommend if you don't have a team of burly builders as the window and upstand (mine was 3.2m x 1.3m) is exceptionally well made, robust and very heavy!

EOS Rooflights provided two high quality rooflights which were well well made (when compared to others I have seen), with good customer service from Elliot and Chris including drawings and installation advice. The delivery company were however a disappointment, using a lorry which was too high for the builder to safely unload from, and a driver who couldn't be less bothered. EOS recognised this and offered compensation.
