Double Membrane Roofs
PERMADOME® Double Membrane Roofs are a well-established solution for use in anaerobic digestion processes offering a cost effective pressurised sealed gas collection roofing solution.
Utilising high quality reinforced thermoplastic membrane materials that provide a high resistance to gas permeability and UV degradation the PERMADOME® Double membrane roof provides a durable cost-effective, optimal performance solution for anaerobic digestion and biogas applications. During operation, the outer membrane remains permanently inflated while the inner membrane inflates and deflates in proportion to biogas production. The operating characteristics of a Double Membrane roof makes it a suitable option for biogas pressurised process applications.
