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..

Why We Choose to Always use Lamiated 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 ridgity and will eventually come falling down. Although rare, it is a risk we prefer not to take for everyones safety.

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.

Jonathan Tregidga Buyer at Legacy

At Legacy we design and build quality homes and properties. A Key part of this is to have a product that fits the bill and EOS rooflights have never failed to impress us on the quality of the item and the staff at the office also never fail to impress. If you need a fixed rooflight then you could do far worse than go with these guys.

I researched several roof lights and found that Chris Higgins and his colleagues at EOS provided the best technical advice and were happy to address my questions quickly. I purchased the roof light in September 2021. It was very heavy and there were issues with the delivery schedule which was stressful due to the additional manpower I needed to offload etc. EOS customer service did address the issues and I am delighted with the quality of my new roof light. I would like to thank Chris, Natalie, and the team for their help.

We are very happy with both the product and the service we received from the company. The roof light is of excellent quality at a competitive price and the customer service was excellent. It is always good to be able to contact a company once you have ordered a product and this was certainly the case with EOS Rooflights Ltd. Unlike a number of other companies we have had to deal with during our building project.

I sent in the order for the roof light and received delivery in 4 weeks, at the moment anything that includes glass is taking ages so I was surprised when it turned up on time.

We have used EOS Rooflights on a couple of projects now and will continue to do so. The quality of the frame which is welded, and the glass connection, is second to none, and this makes for a trouble-free installation. Hillbuilt Construction

I did a lot of shopping around when trying to find the right product for our extension roof and the EOS Flex electric stood out in terms of price and overall quality. The ordering and delivery process was fantastic (within a week it was with me) and it took less than an hour to install. Really happy with the quality and finish so wouldn't hesitate in recommending to anyone looking for similar

EOS where very helpful throughout, the pricing was competitive with all the quotes we received and the walk-on rooflight was exceptionally well made. We prepared the opening using EOS details and plans and it came exactly as described and fitted perfectly (this seems obvious but surprisingly doesn't always happen). I would 100% use them again and would recommend EOS to others without hesitation. I am extremely pleased with the finished rooflight and it looks brilliant installed. My contractor said it was perfect and came exactly as described too, so good all round.No pictures at present but can provide later! It looks fab!
