The Model TGF 21" features a flexible tunnel that can be installed quickly around attic obstructions, making it the easiest tubular product to install in the industry.

VELUX SUN TUNNEL™ skylights admit passive light from the Sun without the normal heat emitted by electrical light sources.  This Sun Tunnel kit includes an exterior dome, flashing, 8 feet of flexible tubing, and a ceiling ring and frosted diffuser.  See related items below for optional accessories such as flexible tunnel extensions, a universal electric light kit, a blackout shade, a turret extension, or a fresnal diffuser replacement.

This skylight kit will span up to 8 feet.  Tunnel extensions are available.  The maximum recommended installation length for the 21" tunnel is 12 feet. The rigid tunnel will span a longer length with good light capture.

The TGF model includes a low profile or 'no pitch' flashing for an integrated look with the roofline.

The TGF model offers two dome options - a standard acrylic or high-impact polycarbonate for hurricane prone areas and a tile kit for installation on a tile roof.

The Velux Sun Tunnel skylight kit comes with a pre-assembled ceiling ring and paintable ceiling trim ring to complete any look. The skylight features a dual diffuser that reduces the chance of condensation and increases energy efficiency while providing even light distribution through a frosted diffuser. An optional fresnal diffuser is available (see related items below). 

The standard flashing is designed for low profile roofing materials such as shingles and shakes. Tile flashing is also available. The Velux TGF Sun Tunnel skylight installs on roofs with slopes between 14° (3:12) and 60° (20:12).
