Puraflex VOC Membrane
Verified by manufacturer 4 months ago
Gas membrane designed for use in applications where combined damp proofing, VOC and gas protection is required. Generally used within foundation constructions.
Application
Generally used within construction applications, predominantly within the foundation design.
Description
A high performance hydrocarbon and chemical resistant barrier with resistance to a wide range of pollutants including hydrocarbons, industrial chemicals, toxic waste, natural and radioactive gases. It acts as a high performance DPM and comprises of protective polymeric layers either side of a chemical resistant inner core.
Features and benefits:
- Provides additional damp proofing protection to the structure.
- Robust membrane construction.
- Resistance to both puncturing and tearing.
