DERBIGUM® SP FR is a fire resistant bitumen-APP waterproofing membrane.
DERBIGUM® SP FR membrane consists of a compound of special bitumen modified with noble polymers (TPO) and two different reinforcements: one in glass fibre and one in non-woven polyester.
The specificity of the compound and selected raw materials ensures the longevity and fire resistance of the membrane.
The glass fibre reinforcement provides excellent dimensional stability as well as heat and UV resistance.
The non-woven polyester reinforcement improves impact and tear resistance.
