A white roof keeps the heat out

A black roof absorbs the sun's heat and transmits it down into the building. A white roof reflects the rays back, and this can be felt immediately under the roof.

It matters most in warehouses and workshops, in summer houses and garden houses with a flat roof, and in garages, carports and conservatories where the roof sits close to the space below.

The membrane is the same as the black one. Same seamless, 100% waterproof surface and same lifespan, just in white.

  • Reflects the sun instead of absorbing it

    A black roof absorbs the sun's heat and transmits it down into the building. The white surface reflects the rays back, making the roof noticeably cooler to stand on and reducing heat loss underneath.

  • Cooler indoors on the hottest days

    Less heat through the roof means lower temperatures in the rooms below. This is most noticeable in warehouses, workshops, summer houses and conservatories, where the roof sits close to the room and there is no air conditioning.

  • Less heat movement in the roof

    A roof that doesn't get as hot expands and contracts less. It's precisely this movement that over the years strains joints and flashings, so a cooler surface is also a quieter construction.

  • Better conditions for solar cells

    Solar cells lose efficiency when they get hot. If they are on a roof that reflects heat instead of collecting it, they work in cooler conditions than on a black surface.

  • Same membrane, just white

    Seamless and 100% waterproof as the black one. Same elasticity of up to 300%, same 25 year product warranty and same expected lifespan of up to 40 years. 20 kg covers up to 13.3 m².

  • You can put it yourself.

    1-component and ready-mixed. Apply with roller or brush in one coat, without gas burner, multi-stage primer or authorized installer.

From black and warm to white and cool

Hidden leaks start in the joints

Your joints are often the most exposed places on the roof – and water can penetrate here without you noticing.

Small cracks and movements can quickly develop into major damage.

With a liquid roof membrane, joints and transitions are sealed seamlessly and fully enclosed, without any nails, screws or welding, so your roof remains tight and protected for many years.
