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.

Ease of installation and provided a huge amount of light to our extension. We chose the electric opening option which is fantastic for ventilation.

The rooflight itself is a great addition to our house; we are very pleased with it. It was simple to contact EOS on the 'phone and they were quick to answer any queries we had. (One query was just as we were installing the rooflight so we needed a quick response!)
