Glass Top Sun Tunnel Skylight (Tubular Skylight / Solar Tube) Replacement (VELUX TZR, TZRL, TLR)
Natural Daylight for Small, Enclosed Spaces — Without Wiring or Heat Gain
The VELUX Glass Top Sun Tunnel Skylight is a compact, energy-efficient daylighting system that channels natural light from your roof into interior spaces where traditional skylights don’t fit.
Also known as a tubular skylight or solar tube, it’s ideal for hallways, closets, bathrooms, and stairwells — areas that typically lack windows or ceiling access.
The model lineup includes TZR, TZRL, and TLR, all offering a durable flat glass top, high-reflectivity tunnel, and easy installation with minimal roof impact.
Sun tunnels deliver bright, consistent daylight all day long — with no energy use and zero heat transfer.
