Description
A high performance gas membrane for use in situations where resistance to methane, carbon dioxide and/ or radon gases is required. The multilayer 0.4 mm thick membrane includes an ultralow permeability aluminium foil core encapsulated between a number of additional low density polyethylene (LDPE) layers and a reinforcing grid to form a single sheet membrane.
Features and benefits:
- Resistance properties with low permeability to ground gases including methane, carbon dioxide and radon.
- Provides additional damp proofing protection to the structure (no requirement for a separate DPM).
- Reinforced membrane construction with high resistance to both puncturing and tearing.
- Complies with relevant industry codes and guidance including CIRIA and BS 8485:2015+A1:2019.
