VELUX Fixed Skylight Replacement (FSR) series skylights are designed specifically for the replacement of old skylight installations. The core design behind the FSR series replacement skylights ensures ease of installation when replacing an existing skylight. The 2.75'' deck seal spans a wider area allowing for coverage over inconsistent and/or less accurate preexisting openings. The FSR line of skylights use standard VELUX engineered flashing and come with a '10-year No Leak Warranty'. Matching existing construction and minimizing or avoiding trim work has never been easier thanks to the no-drywall groove built into the interior of the FSR series skylights.
Note: In general FSR skylights allow a finished opening variance of 2" on width and height for an ideal fit where the front of the drywall will be under the white skylight frame. An additional 2" in width and height variance will allow the skylight to fit the opening, but additional trim will be required.
