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.

We met EOS at the Homebuild Show in Birmingham as we wanted to see the rooflights before we bought them for our extension. We met with Elliot who answered all of our questions and helped out with our plans, as one of the sizes needed amending. The rooflights look beautiful in our kitchen. I would highly recommend EOS to anyone, especially if you this is your first build. Elliot couldn't of been more helpful with answering our queries.

Our roof light with rain sensor add so much to our new extension. The window is great. EOS were a great help with waiting for our builders to be ready to install.

The EOS rooflight we have installed is fantastic, the light within the room now is beautiful, the rooflight itself is a modern, slick design, it has transformed the space!

The finish is very good and the rooflight looks lovely. However, my builder has advised to be prepared for it to be a bit fiddly to fit. Now it is up, it looks great and is definitely how I had hoped it would look. Well worth the purchase.

The people we dealt with on the phone were both polite and very helpful with our order, dealing with the whole process very efficently. The rooflights were delivered to site and our customers were very pleased with them once installed and the effect of such extra light into the extension. We would recommend EOS Rooflights as did visit other manufacturers prior to ordering them but found them to be a superior product overall.

I looked at quite a few of the competitors roof windows and none compared to the quality of EOS Rooflights. In situ, they look fantastic. I wanted to construct my own insulated up stands and the sales team at EOS provided plenty of quick technical info to assist. I also need to delay my order and EOS kindly agreed to store a large roof window for a couple of weeks until I had space on the job site. If you are planning to construct your own insulated up stands, beware of the amount of time it will take you or your carpenter and factor this cost against buying the up stands from EOS (you will need an onsite table saw, unless you have a workshop and adequate space for a glue up). Make sure you have a plan on how you are going to get the roof window to its final location prior to purchase-one of mine was 2.8m long and weighed circa 250kg-I had a relatively easy route to the installation point , but I doubt this will always be the case.

From the outset I received excellent service. I enquired about fixed, opening and bespoke roof lights , both Elliot and Chris provided all the information I required. The order was placed and the deliveries were made on time. Following delivery I raised a couple of installation queries and received a speedy response. Very happy with rooflights, and 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
