What is a sun tunnel?
What is a sun tunnel?
A sun tunnel lets you bring daylight into rooms where you normally don't have windows. The product penetrates from roof to ceiling, channeling natural light from the outside into windowless rooms. Rooms with limited possibility for a traditional roof window, and rooms, you can otherwise only light up with artificial lighting.
If you have a bathroom with no windows, a dark corridor or dull wardrobe space, you can benefit from a sun tunnel. They are available for both flat roofs pitched from 0 - 15° or for sloped roofs with a pitch between 15 and 60°.
A sun tunnel is a cost-effective way to bring daylight into dark rooms. It is also called a light tube, and it is very easy and quick to install. In most cases it will take a few hours to get everything in place.
Why choose VELUX sun tunnels?
VELUX sun tunnels can illuminate areas where you never felt it was possible, bringing natural light to the heart of your home. Here are three other benefits:
1. Easy installation
VELUX sun tunnels are designed for quick and straightforward installation, often completed in just a few hours.
2. Cost-effective
By reducing the need for artificial lighting during daylight hours, VELUX sun tubes can help lower your energy bills.
A roof light tube features a panel sitting discreetly on the outside of your roof, that effectively reflects the sunlight and channels it into the room, and a diffuser that distributes the natural light.
3. Versatile design
Available for both pitched and flat roofs, there's a VELUX sun tunnel to suit every home.
Impressive illumination, every time
We understand that every home is unique. That's why we offer two types of sun tunnels:
Rigid sun tunnels
Our rigid sun tunnels feature a straight tube and a super-reflective coating that ensures up to 98% light reflection. This tube is ideal for direct installations.
Flexible sun tunnels
Our flexible tunnels are particularly clever, allowing you to bypass structural elements like beams or air conditioning units that might otherwise obstruct the light's path.
While our flexible tunnels are designed for shorter roof-to-room distances, don't be fooled by their indirect route. These ingenious devices still deliver an impressive amount of natural light, transforming your once-dim spaces into bright, welcoming areas.
Installation and maintenance
VELUX sun tunnels are designed for easy installation and minimal maintenance. While we don't offer direct installation services, we have a network of VELUX Certified Installers who can expertly fit your sun tunnel.
