Roof Lights & Lanterns
When it comes to illuminating your living spaces with soothing natural daylight, there's nothing quite like roof lights. Also referred to as glass skylights, lantern lights, or glass domes, these architectural marvels create openings in the roof that allow the sunlight to pour in. At John Knight Glass, we take pride in offering a diverse selection of roof lights to transform your space.

We have a huge range of roof lights including our very own bespoke range meaning if you can dream it we can make it. With advances in modern glazing technology there are very few limitations on what is possible with a modern roof light.

Structural Glass
At John Knight Glass, we take immense pride in our commitment to staying at the leading edge of glazing technology. In recent years, we have invested substantially in state-of-the-art equipment and developed our structural glazing solutions for the domestic market. Our all-glass Oriel Windows are particularly popular at the moment, and thanks to our unique base system, we can offer them at a very competitive price.
