Where to install VELUX Commercial SUN TUNNELS

VELUX Commercial SUN TUNNEL™ skylights are designed for flat or low slope commercial roofing applications that are above spaces that will benefit from daylight, thereby reducing energy loads and improving occupant’s performance and comfort.

Ideal applications for commercial SUN TUNNEL skylights include schools, retail spaces, and warehouses that require a cost-effective daylight solution. The round, highly reflective light shaft requires less assembly time compared to previous commercial SUN TUNNEL skylights.

VELUX SUN TUNNEL skylights provide a cost-effective method for transferring daylight through the roof. Cost savings can be achieved with open ceiling applications.
