Installation requirements

Sizes are the overall outside size of the rooflight. Your upstand / framework must be 60 mm smaller each way.
The upstand must be at least 75 mm above the finished roof level.
Ideally, build the upstand with a 1:60 fall.
An insulated thermal break is needed on the inside of the upstand. This can be done with an insulated slab fitted up to the underside of the glass.

Notes (optional)

Before you order: check your sizes

Enter the overall outside size of the rooflight. Your upstand / framework must be 60 mm smaller each way than the rooflight. For example, a 1000 x 1500 mm rooflight needs a 940 x 1440 mm framework (outside size). Bespoke rooflights are made to the size you order. Not sure? Send Ivor a photo and your measurements on WhatsApp first.

I understand my framework must be 60 mm smaller each way than the rooflight size, and I have checked my measurements.
