Our roof lanterns and flat skylights can be tailored to your preferences. Configure the colour of the framework, its size and a range of other intricate details.


Double glazing and thermally broken aluminium contribute so that these roofs are energy efficient. U-values can be as low as 1.3 W/m2K if you choose our fantastic flat skylights.


The robust materials used in both these roof systems make them incredibly sturdy. They are also weatherproof, meaning our roof lanterns will never rust, rut or warp over the decades.

We are registered installers of the industry leading Korniche roof lantern. These hipped roof systems are fitted on top of a flat roof. This makes them perfect for orangeries and house extensions, as well as above kitchens, dining rooms or any other flat roofed area of your property.

Manufactured using die-cast aluminium, these robust roof lanterns allow natural light to flow into the room below. All the while, they deliver stunning aesthetics that can blend with any property style. They make a genuine difference to your day to day life, with a lifespan measured in decades, not just years.

For a price specific to our Titan flat skylights, contact us directly.

Which is better – a roof lantern or a flat skylight?

With their different designs, we don’t believe one is outright better than the other. Instead, one of the two will suit your renovations better.

Roof lanterns are often larger, with a hipped design that permits more light transfer. Meanwhile, flat rooflights are smaller and can be strategically fitted as a result.

If you’re unsure which suits your home more, contact us today!

Replacement Conservatory Roofs Ipswich

Very happy with XL Windows. I went to a number of different window companies in the area for quotes. Some were outrageous, others never returned my call. Chris from XL Windows came round, measured up and gave an incredibly reasonable quote for replacing my bay windows. The service and reassurance throughout was great and I didn't even have to pay anything until the job was done and I was happy with the result. Highly recommend.
