Do you need a Price?

No matter where you choose to install your roof light; you want to know that it will be safe, secure and energy efficient. A large factor in ensuring that these needs are met is in the thickness of the panes that make up your unit.

Whether it is being installed to the roof as a fixed, opening, or Eco model, or if you are adding a Walk On unit to your basement or terrace, there are a few factors to bear in mind to make certain that the glass is dense enough for its purpose.

The importance of thickness

Like windows, roof light performance is covered by building regulations and to comply must meet a minimum U value of 1.8 W/m2K. If the panes are not well insulated, you will lose heat from your home in the colder months, and gain it in the warmer ones. Thicker glass will perform better when it comes to the flow of heat, which will save you money on energy bills for central heating or air conditioning.

On top of this, peace of mind is granted from the security of density. A poor performing unit can act as an additional entry point for thieves or a weak spot for environmental damage.

The measurements

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.

Glazing and glass type

The type of glazing is also important to consider. Almost all products on the market are DGU (double glazed units) as single glazing would simply not do the job of keeping your home secure and warding away the elements.

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 an outer pane of toughened and inner pane of laminated glass offers significant security benefits.

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 25mm toughened & heat strengthened laminated outer pane and 8.7 mm laminated low e inner pane.

Depending on the product, the structure and make up of the glass will be slightly different to suit its purpose, On Eco models the glass will be triple glazed with a cavity that is injected with Krypton or argon gas which significantly improves its energy efficiency. Again, the outer pane will be toughened, with a laminated inner one to reduce the chance of damage.

All of our roof lights are made with high criteria specifications as standard. If you want to know more about the glass we use, or have any other questions before choosing your product, call us today on 0208 462 3557 or take a look at our Fixed, Opening, Eco, or WalkOn Rooflights pages for more information and to see our stock sizes.

Great company to use - very helpful with pre-order enquiries, and we’re very accommodating when organising delivery dates and details. I would be happy to recommend EoS.

Very easy transaction, great product and delivery service was fantastic. Only constructive feedback I can give is to better highlight the weight of the product and that can/will cause issues with delivery and installation. Luckily we had 6 builders on site who between them managed to move the £140kg roof light but what that meant is that we had to pay extra to re-enforce the roof with different beams

Chris was a great help in selecting my roof lights. Quick delivery for 3 stock roof lights and the builders had them installed without a problem. The one opening roof light has not been connected so I wait to see how it works after our extension is complete.

Our rooflights from EOS look stunning and 'make' our room. Our extension is flooded with light. The electric one functions really well. We couldn't fault the service from EOS. They were so helpful, especially as we needed a bespoke size rooflight. I did a lot of research into which rooflights to buy and EOS were the most cost-effective by far, and theirs is a quality product. Thanks to the entire team at EOS. We wouldn't hesitate to recommend you.

Good price, helpful on information delivered promptly and well wrapped. Delivery cost seemed steep but I don't think that was under their control.
