VCS 2246: Narrow Profile, Powerful Performance

The VELUX VCS 2246 is a solar-powered venting curb mount skylight designed to bring natural light and fresh air into long, narrow spaces like kitchens, hallways, and bathrooms. Its sleek proportions—22½" x 46½" inside curb dimensions—make it ideal for homes with limited rafter space or where grouped skylight layouts are desired.

With a built-in solar panel and concealed battery, this skylight operates without any electrical wiring. It opens and closes via remote control and includes a rain sensor that automatically closes the unit when inclement weather is detected. The Laminated Low-E3 glass enhances safety and energy efficiency while meeting code for out-of-reach applications.

Designed for an outside curb dimension of 25½" x 49½", the VCS 2246 is compatible with roof pitches from 0° to 60°, and qualifies for a 26% Federal Solar Tax Credit. As always, it's backed by the VELUX 10-year no-leak warranty when installed with approved flashing kits.

Curb Mount

A curb-mounted skylight is designed to sit on a raised curb structure built on the roof, making it a flexible option for both new installations and replacements.

 

Curb-mounted models are ideal for flat or low-slope roofs and can simplify installation—especially when replacing older units or working with thicker roofing materials.

Roof Pitch

Compatible with roof pitches from 0:12 to 20:12 (0° to 60°).

 

Ideal for flat and low-slope roofs, or where an existing curb is already in place. A great choice for retrofits, replacements, and homes with roofing materials like torch-down, TPO, modified bitumen, or tar & gravel.

Flashing

ECL Low-Profile Flashing – Suitable for low-slope and flat roofs, commonly used with membrane or rolled roofing systems.

ECW Step Flashing – For use with shingle and shake roofs (minimum pitch 3:12). Designed to integrate with typical roofing profiles and provide weathertight protection around curb-mounted skylights.

EMW Metal Roof Flashing – Specifically made for standing seam and corrugated metal roofs, ensuring a custom fit and secure seal.
