Opening Flat Rooflights

Simple, sleek and safe – our Flex Opening rooflights come with a very high level of testing and certification with a simplified and contemporary look. The electrically opening model is designed for installation onto a builders kerb (also known as an upstand*). Hidden motors add to its elegant finish.

Streamlined contemporary design

Fast Delivery and 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,
nationwide via our Online Shop.

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 at all time

IThe Flex system has been tested for impact resistance (to CWCT Class 1) to ensure the highest safety standards. This means, as with all our products, your roof window will not shatter and ‘rain’ into your home if broken.

All of our rooflights feature a laminated 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.

Contemporary Design

Designed for installation onto a builders kerb, the design of our Flex Opening Rooflight ensures a low profile incorporating hidden motors for a seamless finish.

Opens at the touch of a button

Our electrically hinged rooflights include a switch as standard with additional remote and rain sensors available as optional extras. Please ask us for more information.

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 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

EOS where very helpful throughout, the pricing was competitive with all the quotes we received and the walk-on rooflight was exceptionally well made. We prepared the opening using EOS details and plans and it came exactly as described and fitted perfectly (this seems obvious but surprisingly doesn't always happen). I would 100% use them again and would recommend EOS to others without hesitation. I am extremely pleased with the finished rooflight and it looks brilliant installed. My contractor said it was perfect and came exactly as described too, so good all round. No pictures at present but can provide later! It looks fab!

We purchased a flat roof light last year and we're so glad we did. It's made such a difference to the light we get into the room and looks amazing too. Top product and great results. Our builder was impressed with it too and how quickly his question was answered when he was installing it.

As part of my build project I researched many companies looking for good quality skylights and a company that could offer both opening and fixed skylights. EOS fitted all my requirements. Both Elliot and Chris were consummate professionals in dealing with my queries and ensuring I got my delivery on time. The skylights were solidly constructed and we love them. The only thing I will say is that if you order a bespoke size, make sure you can wait 6 weeks from order to delivery.

Delighted with our rooflights. EOS did everything they said they would do when they said they would do it. We were a bit nervous about doing our own fitting but we got precise, practical instruction diagrams and all went very smoothly
