Product Description

If you have an internal room, such as a bathroom, that you can't install windows on the walls or roof, a sun tunnel will channel daylight from your roof into the room below.

How does it do this?

The highly reflective tube transports daylight from your roof top through to the room below. The best route between rooftop and ceiling is the shortest, however, sometimes you will have obstacles in the way and so a flexible tube comes in handy. It allows you to get around fixed items in your roofspace without losing too much daylight in the process.

Each Sterlingbuild flexible solar tube kit includes:

  • Roof flashing panel
  • Flexible tube with bayonet connector
  • Lower tube ceiling mounting ring
  • Easy to fit double glazed ceiling diffuser with ventilation facility
  • Installation fixings pack
  • Comprehensive fitting instructions

Please see 'Other products you may be interested in' on the right hand side of the page, as you will also need to purchase an upstand for installation of a Sterlingbuild sun tunnel.


Hallways, bathrooms, cupboards under a pitched roof that can't have roof or vertical windows.
