Tri-Gas Membrane is a high performance gas membrane for use in situations where resistance to methane, carbon dioxide and/or radon gas is required.
Generally used within construction applications, predominantly within the foundation design.
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.
