PITTCOURSE™ 100 High Performance Damp Proof Course

Description

PITTCOURSE™ 100 DPC is a high-performance, modified bitumen sheet designed as a non-metallic interleaving layer for FOAMGLAS® insulation in tank base systems. Comprising a reinforced polyester base and finished with fine sand on both sides, it acts as a durable damp proof course that protects against moisture ingress in both cold and cryogenic tank applications.
