The DERBIT product range are Dual reinforced membranes (Fiberglass mat + Spun bond Non-woven Polyester) giving it a life expectancy of more than 30 years. The reinforced fiberglass mat on the surface gives the membrane a perfect dimensional stability. The membranes also have a UV protection in the blend due to high grade APP polymers and therefore don’t need to be protected by slates on the top. Additional protection coating is recommended to gain additional serviceable life of the system over many years but is not an absolute necessity.
The DERBIT product range is fire retardant and tested along the European standard ENV 1187-2 (Broof t2) making it a suitable first choice for high rise buildings, hospitals and shopping malls.
