Brighten Your Home with Velux Sun Tunnels

No matter how well-designed a property is, there are always those awkward, windowless spaces that feel isolated from the rest of the house. Hallways, cloakrooms, stairwells, and small bathrooms often rely entirely on artificial lighting. Velux Sun Tunnels solve this problem by channelling natural light directly from your roof profile into your home via a highly reflective tube.

Choosing the right daylight system doesn’t just cut down on your energy bills; it also dramatically improves the feel and visual space of your interior.

Velux Pitched Roof Sun Tunnels vs Flat Roof Tunnels

The architecture of your roof determines which category of tunnel you will need:

  • Velux Pitched Roof Sun Tunnels: Specially designed to integrate cleanly into sloped roofs. They are supplied with integrated black polyurethane flashing frames that guarantee a watertight fit and blend in perfectly with slate or tiled roof profiles.
  • Velux Flat Roof Sun Tunnels: Ideal for flat-roof structures, utilising a sleek, weatherproof dome design that captures daylight from all angles.

Rigid vs Flexible: Which Tunnel is Right for You?

When selecting your sun tunnel, the run distance and path from your roof to your ceiling will dictate whether you need a rigid or flexible design:

  • Rigid Sun Tunnels (TWR / TCR): Best used when there is a straight, unobstructed path between your roof and your ceiling diffuser. Equipped with a super-reflective mirror lining, rigid tunnels offer up to 98% internal light reflection, making them the absolute best option for maximising brightness over longer distances (up to 6 meters with extension sections).
  • Flexible Sun Tunnels (TWF / TCF): Ideal for shorter distances (typically between 0.4m and 1.5m) where structural beams or attic obstructions make a straight run impossible. The fibreglass, easy-to-bend tubing allows you to navigate around joists easily during installation.
