VELUX Installation Instructions


When installed correctly, a VELUX skylight, roof window, or sun tunnel can provide natural light throughout the homes you build for years to come. 


Backed by the most extensive warranty in the industry, VELUX skylights are put through rigorous tests and built to the highest standards to ensure a long-lasting product for your homeowners and an easy installation for you. When installed with our flashing kits, VELUX skylights are guaranteed not to leak. That's our promise and an assurance you can pass along to homeowners who may be hesitant about installing skylights.


Where to Find Installation Instructions

All VELUX products come with simple, step-by-step illustrated instructions for installation. PDF versions of the instructions are also available to download on our website. Just go to and select the "Professional" link beside our logo at the top. From there, click Tools, then Architects, then Drawings and specifications under Technical Info.
