your questions answered

Common questions

Do I need planning permission for my skylight?

In England and Wales planning permission is not usually required for the installation of new rooflights, subject to the current limits and conditions stipulated by the government’s Planning Portal under Schedule 2, Article 3, part 1, class C permitted development.

Is this skylight thermally broken?

Our entire range of contemporary rooflights are truly thermally broken to help your property stay warmer and drier. For a skylight to be entirely thermally broken you should expect to see polyamide sections dividing all materials that sit across the internal to external parts of your building. This is the only effective means of maintaining insulation and, subsequently, the climatic control of your property.

How high does the upstand need to be from the roof surface?

The upstand must be fully weathered to 150mm above the roof surface at its lowest point.

What does the BSI kitemark mean?

In 2014, our skylights secured accreditation from the British Standards Institution (BSI) for the air permeability, weather tightness and wind resistance against BS 6375-1:2009 of our SkyView, Aero, Horizon and Pyramid skylight products. As the UK’s first flat roof skylight manufacturer to receive such verification, this means you can buy in confidence knowing that we are committed to best practice, continuous improvement and providing you with skylights that meet strict performance targets.
