Features & Benefits: Novia Methane Pro Damp Proof Membrane & Gas Barrier – 1.6m x 50m Roll

• Premium multi-layer laminate DPM with reinforcement and aluminium foil core
• Acts as a methane, CO2, radon gas and dampness barrier
• Installed with the blue side down and silver side visible on the floor
• Used with 50mm double-sided butyl tape for joining and sealing
• 50m length x 1.6m width
• Convenient 80m² roll size
• 27kg roll weight

During installation, ensure flawless execution by employing the Novia Dual Tape Sealing System. This involves using 50mm double-sided butyl tape to join and seal the product, along with BOPP metallised tape to secure the laps and edges. Without these tapes, the methane barrier is rendered ineffective, failing crucial tests and risking leaks. Safeguarding against toxic and flammable gases escaping necessitates proper sealing.

When laying this Novia Methane Pro, the blue side must face downward, allowing the silver side to be visible on the floor. The product’s composition, with its multi-layered laminate design, mandates that the silver side always remains on top. Any presence of blue indicates incorrect installation.
