VELUX Rigid Sun Tunnel (TCR)

The VELUX Rigid Sun Tunnel (TCR) is engineered to deliver bright, natural daylight into internal rooms where traditional skylights are not suitable. Designed for flat and low‑pitch roofs, its rigid, highly reflective tunnel provides superior light transmission, making it ideal for hallways, bathrooms, closets, and other compact spaces that benefit from stronger daylight levels. The TCR integrates cleanly into both the roof and ceiling, offering a simple, effective daylighting solution with minimal structural impact. With its energy‑free operation and reliable performance, the Rigid Sun Tunnel is a practical choice for brightening dark interior areas in contemporary flat‑roof designs.
