Product details

Leadax Roov is the revolutionary circular flat roofing membrane made from plastic waste. This smart flat roofing material is reflective off-white. This keeps the indoor temperature low, but increases the output of solar panels on the roof. 

The product is made from recycled PVB foil: a residual stream from safety glass. It is highly recyclable and has a much lower environmental impact than comparable flat roof solutions. After the expected lifetime of about 30 years, the product can be easily dismantled and then recycled and reused to make new products. 

Leadax Roov is easily applied without using open fire or hot air. This makes it compliant with NEN-EN 13501-1 (NEN 6065). Also, the circular material for flat roofs is fire resistant (class Broof(t1)). This means that it is resistant to sparks being blown away by a strong wind, such as a nearby fire or flare.

Leadax Roov can be applied to different types of roofs

Several types of roofs can be combined, this is called multifunctional roofs. For example, consider a water roof with a green roof. What are they? Below you can read more about them.

White roofs

Leadax has chosen to make Leadax Roov offwhite for several reasons. Most roofs in the Netherlands are covered with black bitumen. This makes sure that these roofs can reach a surface temperature of 80 °C. Cooling this down requires more energy than heating it up. White roofs reflect sunlight, keeping the building cooler.

Solar panels

Furthermore, white roofs are also very suitable in combination with solar panels. The reason for this is that solar panels have poorer electrical conductivity at a higher temperature, which reduces their efficiency. White roofing under the solar panels ensures that there is less heat radiation on the roof, so the solar panels stay cooler and generate more energy.
