How to Choose Your Size
When ordering your Circular Rooflight, it’s essential to select the size based on your external upstand dimensions to ensure a perfect fit.
- If you plan to order a 1000mm x 1000mm rooflight, the external upstand dimension should also be 1000mm x 1000mm.
- Please note that our sizes include a 20mm tolerance, meaning the actual rooflight size will be 1040mm x 1040mm.
This built-in tolerance ensures a seamless fit and easy installation, accommodating slight variations in upstand dimensions.
