Flood your home with light

With good light being so important in a modern home, it’s no surprise that the demand for flat-roof lanterns is steadily increasing. And with our flat roof lights, that’s exactly what you get.

Flat roof lights are a great way to welcome fresh light into your home with a modern, subtle aesthetic, and are perfect for illuminating tight rooms or areas with minimal window space.


A flat roof modern skylight can seamlessly transform the lighting of any room it’s installed in. Made from two layers of high performance glass, there are no connecting bars. Combine this with our hidden internal fixings masked by your wall, and you get a skylight that blends flawlessly with your roof.

Both classic and modern in style, our flat roof lights offer exceptional thermal performance, and their slight timber pitch allows water to flow easily off your skylight while keeping the heat in.

Specifically designed to accommodate a low-profile skylight, our XP Skyview skylight can be manufactured in a wide range of sizes, and specifications – whatever you need to fit your skylight plans.


Our flat roof skylight windows are deceptively simple, yet built with the same structural strength in mind as our lantern roof lights, exceeding the recommended requirements to keep your home protected – no matter the weather. Our flat roof lights can even be triple-glazed for maximum thermal efficiency.

And like all our roof products, our flat roof lanterns are designed and manufactured in our own facility before being installed on-site by our team of technical experts. They’ll work hand-in-hand with you throughout the installation process to bring your dream project to life.

Opening Rooflights Available

Our new opening rooflight is available in either electric or manually operated versions, boasting market leading U-values along with industry-leading water tightness using our triple seal system. Our opening rooflight is still virtually frameless internally for a sleek and modern look, whilst externally the minimal framework creates a slimline
appearance, which is the perfect complement to our range of door and window products. Our opening rooflight is offered with heat soaked toughened glass as standard and a glass U-value of just 1.0.

Fixed, manual or electric opening
Fixed skylights are a stunning architectural product but the ability to open them for ventilation is popular in rooms such as kitchens and glass rooms. The performance of the skylight is not compromised by it's ability to open and we can offer this functionality either with a manual winder and pole, or hard wired electric operation.

Bespoke Solutions Available
In certain locations we can offer bespoke solutions for oversized glass roofs. We will only offer these solutions under strict site conditions because although we manufacture the roof frame in-house, the structural bonding of the glass must be carried out on site. This key process is affected by environmental factors because the structural bond required for oversized roofs does not correctly adhere to the glass and frame in wet conditions or in cold weather below 7°C. Please contact our team to discuss our specific requirements if you are looking for a bespoke solution for your property.

What's the largest flat skylight you can offer?

The largest XP SkyView we can manufacture and install is 3000mm x 1000mm. The widest is 1400mm x 2000mm, we have a size chart on our product specification sheet than can be downloaded from this page.
We can also structurally join our roof lights to create even larger bespoke skylights.

What does the skylight sit on?

The flat skylight needs to sit on a timber upstand with a five degree pitch. Our sales team can send you information on the upstand required but it is straight forward for the builder to prepare this ready for the skylight but it needs to be a minimum of 150mm high to satisfy building regulations and 90mm thick for the roof to sit on.

Can the skylights only be fitted onto a flat roof?

Because the roof needs to sit on a purpose built upstand the XP Sky View can be installed onto pitched roofs up to 25 degrees.

Can you use triple glazing within the skylight?

Yes, as standard we use high performance double glazing but triple glazing is available on request.
