Let the daylight in – even in the middle of your home

VELUX sun tunnels are designed to add natural light into rooms where a normal roof window just isn’t possible or appropriate. They capture daylight on your roof and send it through a reflective tunnel, filling your room with soft, natural light that shifts organically throughout the day.

It’s not just about making things look better (though they do). It’s about making your home feel more alive. With less need for artificial lighting, you’ll save energy, and those spaces you used to ignore might just become your new favourites.

Why choose a VELUX sun tunnel?

Choosing VELUX means choosing a brand trusted by homeowners and professionals around the world for over 80 years. Here’s why a VELUX sun tunnel makes such a big difference:

Rigid and flexible sun tunnels – which one is right for you?

VELUX offers two main types of sun tunnels to suit different homes and installation needs:

VELUX roof window system with reflective tubes for natural light.

Rigid sun tunnels

If there’s a straight, clear path from your roof to your ceiling, a rigid sun tunnel is ideal. It uses a solid, reflective tube to deliver the maximum amount of light. This is great when you want the brightest possible effect.

Flexible sun tunnels

Got pipes, beams, or other obstacles in the way? No problem. A flexible sun tunnel is designed to navigate around obstructions, making it a great choice for tricky installations. You’ll still get a beautiful flow of natural light, even when space is tight.

VELUX offers sun tunnels designed for both pitched roofs (15°–60°) and flat roofs (0°–15°), with specific models suited to each type of roof. That means there's a solution for almost any type of home.

Simple to look after, built to last

VELUX sun tunnels are made from high-quality materials and built to handle the ups and downs of everyday life. Once they’re in, they don’t ask for much – just the occasional wipe of the diffuser to keep the light coming through clearly.

VELUX doesn’t handle installation directly, but we work closely with a nationwide network of VELUX Certified Installers. They know our products inside out, and we always recommend using one to make sure everything’s fitted properly and performs as it should.

See how natural light changes everything

There’s something about natural light that just makes a space feel better. It lifts your mood, helps your body clock stay on track, and creates a more comfortable, more inviting atmosphere at home.

A VELUX sun tunnel might be a small change, but it can have a big impact, turning underused corners into places you actually enjoy being in. To make the most out of the light intake from the sun tunnel, our Edge Glow light diffuser effectively spreads the natural light from outside throughout the room. It’s a simple way to bring a bit more light – and life – into your everyday.
