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.

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

ordered 1m x 1.5m flat fixed skylight. Very heavy due to extra thick glass. Had to hire an SLA10 Material hoist to be safely lifted onto garage roof but cost was low for a day hire. Now installed looks great. Needs at least two strong adults to lift out of delivery van. Would have been better if delivery van supplied with equipment to offload. Easy to order via website pdf doc dimensions and installation instructions all good and customer service friendly and helpful and informative. Happy to recommend.

This is the second time I have purchased a 2 x 1 mt. non-opening rooflight from EOS. They are extremely well made and use much thicker glass than many other manufacturers. They were recommended to me by a high end door and glass systems company. If you need a rooflight I don't think you will find better than EOS. I am delighted with my purchases​.

as the installers we thought the product well manufactured , expensive , no ventilation , the customer loved it , that's important , installers need to have installation tool box talk.

EOS were excellent to deal with and very good at communicating about their products. I ordered three 1500 x 1000mm roof lights and two 600 x 600mm. The quality is fantastic and my new kitchen now looks amazing. The roof lights make a huge difference and bring in a huge amount off light. Also having one that opens via the electric control panel is a great feature on hot days. Paul. Ealing W5

I am a managing director of a London based design and build company and we use Eos roof lights on many of our projects. I have just put 2 electric opening 2m x 1m roof windows in my own home. I see many roof windows in my line of work and in my opinion Eos roof lights represent excellent quality and value for money.

As a builder having used various different roof lights we continue to recommend and use EOS to our clients for three reasons 1. They give maximum light as the frame is minimal and this makes for a great look inside 2. They are competitively priced in the market 3. They have off the shelf stock roof lights available in 3 - 5 days and have delivered on time every time so far. 10/10 for quality and service
