Sizing Guide

VELUX offers a variety of skylight sizes to suit your every need. The charts display sizes and codes for deck-mounted & curb-mounted skylights to help you with installation.

 

DECK-MOUNTED SKYLIGHTS:

A deck mount skylight is attached to the roof deck. You do not need to build and waterproof to a curb; In this design, the curb is the skylight itself.  

 

CURB-MOUNTED SKYLIGHTS:

The skylight is designed to sit over a curb like a lid on a shoe box. Generally this curb is comprised of 2×6, or larger, construction lumber set on edge and attached to the roof deck. The box is then ‘flashed in’ with the roofing material for waterproofing.

Please note: Custom sized curb-mount skylights are available. Pricing is upon request.
