For example if you order a Lantern 900mm x 1200mm your EXTERNAL up-stand size needs to measure 900mm x 1200mm.

The most important thing to remember when deciding on what size rooflight you require is that the size of our windows (width x length) are measured to the external kerb/upstand, NOT to the size of the hole in your roof or the window itself.

We work to the external up-stand size as the thickness of up-stands can vary and therefore the internal size can vary depending on this. Using the external up-stand size maintains a reference point.

The up stand should be a minimum of 75mm thick and a minimum of 150mm high. It is the responsibility of a structural engineer to ensure the upstands are suitable to withstand the weight imposed by the glazing system and ALL associated loads.

All upstands are to be suitably weathered and the surface to which the rooflight is fixed is to be true and free from undulations.

Suitable for flat roofs of between 0 and 15 degrees, if the roof is less than 5 degrees, the timber kerb must be made at an angle to deliver a minimum 5-degree slope

Frequently Asked Questions

How to measure – Rooflights

Please enter your EXTERNAL up-stand sizes here …….

For example if you order a Lantern 900mm x 1200mm your EXTERNAL up-stand size needs to measure 900mm x 1200mm.

The most important thing to remember when deciding on what size rooflight you require is that the size of our windows (width x length) are measured to the external kerb/upstand, NOT to the size of the hole in your roof or the window itself.

The measurement we require is from the edge of the finished kerb to the edge of the other finished kerb.

The minimum size of the kerbs should be 75mm x 150mm high.

Fixed flat rooflihgts require a 5° minimum fall to encourage water drainage, a maximum of 15° is allowable on any flat roof.
