Fast Delivery at a Great Price

The Flex Opening Rooflight

Available in 15 sizes which are already in stock and ready for free delivery in 2 – 3 days,

Energy Effiency

Our range of Flex Opening rooflights feature motors hidden to ensure its smooth, seamless appearance. Its minimalistic appearance however does not mean a compromise on safety features and energy efficiency.

Again, all of EOS’ rooflights have excellent standards when it comes to energy efficiency. While not as efficient as our ECO range (which features an inbuilt upstand / builders kerb to meet the very highest in U values if you’re looking for unbeatable efficiency), the Flex Opener boasts impressive performance to rival many other premium rooflights on the market.

Safety – a no compromise approach

The Flex system has been tested for impact resistance to ensure the highest safety standards. This means, as with all of our products, even when broken, your roof window will stay intact without potentially dangerous glass falling into the room below.

Featuring a laminated inner pane as standard as part of our uncompromising standards in safety. For more information on the benefits of market leading glass specification, read our latest blog post.

Opens at the touch of a button

Low Profile Framing

Water pooling looks unsightly and can cause issues in roof lights, especially with units that open. Luckily EOS has the solution. All our powder coated external frames finish flush with the glass, ensuring that water slides off effortlessly, leaving your roof light looking its best.

The Flex is also available in a range of fixed rooflights, for Fixed Rooflights click here

I spent months researching and requesting estimates for a large 3m x 1.5m Flat Roof Light; without a join. Which proved a huge learning curve. My builder advised me I should to consider having a smaller roof light or join, which I didn’t want.Thankfully, I managed to find EOS Roof Lights, who were really helpful, knowledgable, efficient and extremely competitive. I now have the Roof Light I envisaged, which looks amazing.Great level of service and fantastic product. Delivery and communications were excellent. Would certainly recommend EOS Roof Lights.Thanks Chris.

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
