Productinformatie
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.Â
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.Â
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.
Other beneftis
- Leadax Roov has a lower CO2 impact than competing products
- The rolls are 12,5 meters long, and 1 meter wide

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.
Energy roofs
Leadax Roov is very suitable to be combined with solar panels (see ‘White roofs’). Solar collectors can also be placed on the roof for heating the building, tap water or a swimming pool. These roofs can also be combined with white and green roofs.
The flat roof covering is only 1.5 millimeters thick, which makes it possible to walk on the roof. For example, to carry out maintenance on the solar panels.
Green roofs
A green roof is just a little bit different from a traditional roof, and Leadax Roov is a good product for that too. There are different types of green roofs, such as moss sedum roofs, garden roofs and roof parks.
Green roofs have several advantages:
– Relieve the burden on the sewer system
– Insulating effect
– Cooling in summer and heating in winter
– Cooling of the ambient temperature
– Contributing to better air quality
Recreational roof
A recreational roof creates more living and/or working space. It is also possible to combine this roof with a green roof, for example for growing crops (fruit and vegetable growing). If the space is not used, it can be rented out, which provides an increased financial value.
Water roofs
Water roofs are built to temporarily store rainwater to relieve the sewer system. After collecting the water, it can be stored on the roof or in a water tank. The water can be filtered and used for applications such as flushing the toilet.
There are two types of water roofs:
– Water roofs that have permanent water on them (higher volume)
– Water roofs that store the water temporarily (lower volume)
Benefits of water roofs:
– Saving on water costs.
– The burden on the sewer system is reduced, thus preventing flooding
– Reduced use of groundwater
– Insulation of the roof
– Possible reduction of sewerage charges
– Possible municipal subsidy schemes
– Payback time approximately – 12 years
