ROOF GLAZING

What glazing options are available for a pitched roof?

We offer several roof glazing solutions which are perfect for a pitched roof. For more information read this article.

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).

Tip: 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, you may wish to consider an alternative roof glazing solution such as the lower-pitched Aluminium Roof Lantern, or the Pure Glass Flat Roof Light.

Where can I see your Roof Glazing?

We have a showroom in Liphook, which is open 9am - 4pm Monday to Friday. Our showroom features the following Roof Glazing for you to view:

What is an upstand?

The sizes featured on our website are external manufactured sizes, so they include an allowance for the upstand and roof covering. We require the measurement to be taken from the face of the external weathered upstand. Please call us if you need further details.

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

The Exact Aluminium Roof Lantern has a maximum size of 6000mm x 4000mm.

What type of drainage is used to achieve a flush threshold?

The type of drainage channel for your project will be defined and sourced by your architect or builder. Based on the flooring and the finish you would like to achieve, it is likely to be slot drainage or aco drainage system. For more information on thresholds visit our news article.

A floating corner configuration allows you to push back 2 glazed walls in a room, without the need for an intrusive fixed corner element. Our Colchester project features this stunning configuration with the CP130 sliding doors.

What is a lift & slide sliding door system?

A lift & slide door refers to the way in which your sliding doors open. Rather than a static rail and small rollers as you would find on an inline door, with a lift & slide door such as the Reynaers CP130, the sash is lifted and hovers above the frame, giving you an effortless, smooth opening movement.
