40x40 cm rooflights

A 40 x 40 cm rooflight for greater comfort on board

After a day in the sun or a night in your vehicle, being able to refresh the air makes your living space more comfortable. The 40 x 40 cm rooflight creates an opening in the roof to help ventilate your van, campervan or motorhome while parked.

Installed above the kitchen area, bed or central space, it helps hot air and moisture escape when conditions allow it to be opened. Depending on the cover’s finish, it can also bring natural light into the interior.

How do you choose a 40 x 40 cm rooflight?

Size alone does not determine compatibility with your vehicle. First check the cut-out dimensions on the product page, then the external dimensions of the frame and cover. Allow enough room for it to open, particularly near a solar panel or roof rack.

Fitting thickness is also essential: it must match the roof thickness, including insulation and lining. If replacing a rooflight, measure the existing opening before selecting a new one.

Then compare features based on how you travel:

• The cover finish, to choose how much light it lets in.

• The flyscreen, for ventilation while helping keep insects out.

• The blackout blind, useful above a sleeping area.

• The opening mechanism, which should remain accessible once the conversion is complete.

• Permanent or powered ventilation, where available on the model.

Preparing to install a rooflight on your van

Before making any cuts, locate the bodywork reinforcements and check the vehicle’s specific installation requirements. The contours of the roof may require an adaptor to provide a suitable mounting surface.

Choose fixings and sealing products according to the manufacturer’s recommendations. Browse our sealants and adhesives for conversions to find the products needed for installation, checking that they are compatible with the materials involved.

Considering ventilation as a whole

A rooflight is part of a wider approach to airflow on board. Depending on your conversion layout, ventilation grilles for vans and motorhomes can complement the installation.

To keep your rooflight in good condition, follow the manufacturer’s care instructions and regularly check that the cover, flyscreen and seals are clean.
