VELUX Sun Tunnels

Whether an extension, converted garage, or windowless bathroom, VELUX Sun Tunnels are the perfect solution to bring the natural daylight streaming in.


Understanding VELUX Sun Tunnels

While many are familiar with the term ‘VELUX window’, the VELUX Sun Tunnel stands out as a unique daylighting solution. It channels sunlight from the roof directly to your interiors, suitable for both flat roofs with a pitch between 0° and 15° and sloped roofs with a pitch between 50° and 60°.

What Is A Light Tube?

Often referred to as a “light tube” or VELUX light tunnel, this innovative product is designed for quick and straightforward installation. The process involves creating an opening from the roof down to the ceiling, inserting the tube, and fitting a dome on the roof’s exterior. Inside, a light diffuser ensures even light distribution, illuminating every corner of the room below.

How VELUX Sun Tunnels Work

The brilliance of the VELUX Sun Tunnel lies in its ability to capture and channel natural daylight from outside. The light tube filters sunlight, allowing it to reach even the darkest corners of a room. This makes it an ideal solution for lofts and other spaces where traditional windows aren’t feasible. With up to 98% daylight reflectivity, you’ll be amazed at how much natural sunlight is directed into your space.

Sustainability And Energy Efficiency

VELUX Sun Tunnels aren’t just about aesthetics; they’re a beacon of sustainable living. By maximising the use of natural daylight, they significantly reduce the dependence on artificial lighting during the day. This not only cuts down on electricity bills but also reduces carbon footprints, making your home more eco-friendly. By choosing VELUX, you’re making a conscious decision to contribute positively to the environment, embracing a brighter, greener future.

Sun Tunnel Types: Pitched Vs Flat Roof

There are two main designs of sun tunnels, designed to work flexibly with the layout of your roof, whether that be pitched or flat. VELUX sun tunnels aren’t restricted by beams or other potential obstructions. They come in both rigid versions with a straight tube and also a flexible version which features an angled tube. This means they can be fitted around anything which prevents installation directly below the roof.
