Sustainable and healthy living under your roof

VELUX roof windows allow natural daylight to flood in, brightening your home.

They also provide the opportunity to have a healthier indoor environment letting in fresh air. This is vital when we consider that we spend 90% of our time indoors and that the air inside our home can be up to 5 times more polluted than the air outside.

With the world facing increasing climate changes, natural energy resources will become a main source of energy. One path- way that can lead us to a more sustainable future is by collecting the sun’s power and converting it into solar energy.

VELUX Solar Integrator ODL Key Features

Perfect fit into the PV grid

Our solution ensures that your VELUX roof window will fit perfectly into the PV grid, providing an easy, fast, safe and seamless integration.


Zero shadow effect

The flashing does not cover or block any active part of the solar panel, ensuring the full utilisation of the panels and maximum generation of energy.


Side sections

Fusion achieves exceptional fire performance, wind resistance and weather tightness without extra roof battens, adhesive flashing rolls or fire proofing materials. Everything you need is right there in the kit.


Robustness test

The design of our unique and innovative side sections allows for up to 25 mm sideways flexibility. This means that we can easily secure the perfect positioning of the solar panels and the roof window
