Bespoke, high quality glazing

Your choice of lantern style

The Exact Pure Glass Roof Lantern is available in two styles; Pyramid style featuring a square roof lantern and 4 identically sized panes of glass to create a pyramid. Or Rectangular style featuring a rectangular roof lantern with a central ridge.

Both styles of lantern are made in the UK using high grade materials, with a built in plastering lip and hidden fixings to ensure the minimalist design achieved externally is reflected inside your property.

How do I calculate the height of my Pure Glass Roof Lantern?

The height of a Pure Glass Roof Lantern is approximately half of the shorter dimension.

E.g. a 1500 x 2500mm roof lantern will be approximately 750mm high (1500mm ÷ 2).

Remember to take into account the upstand height when calculating the overall height of your roof glazing.

Is the pitch of the Pure Glass Roof Lantern fixed?

Yes. The 40° pitch of the Pure Glass Roof Lantern provides its structural integrity. If you are working within a height restriction for your roof glazing, talk to one of our expert team about your project to find out about our other roof glazing systems. The  Aluminium Roof Lantern has a lower-pitched or the contemporary Pure Glass Flat Roof Light will sit on the roof line.

What is the biggest size of roof glazing you can install?

The Exact Aluminium Roof Lantern has a maximum size of 6000mm x 4000mm. If you are looking to achieve a larger span, the modular style of Exact Pure Glass Glass Flat Roof Light could be a perfect solution.
