Derbibrite is the revolutionary ‘cool roof’ waterproofing membrane within the award winning Derbigum range. The highly reflective, acrylic top coat not only helps reduce the urban heat Island effect of buildings to which it is applied, it lowers internal building temperatures and is formulated to allow direct bonding of photovoltaic panels.
Applications

- The reflective surface finish reduces heating/cooling load on the building interior
- A higher performance alternative to PVC single ply
- Suitable for use on warm roofs with metal, concrete or plywood decks
- Equally suited to reroofing or new build projects
- Suitable for flame-free application
- Specifications for a wide range of project types are available
