Environments where where there is a need to prevent harmful gas ingress: Novia Methane Pro 390 Gas Barrier & DPM is effective in environments where there is a need to prevent harmful gas ingress because it provides a multi-layered protection system with a reinforced aluminium foil core. This design offers an impermeable barrier against gases such as methane, carbon dioxide, and radon, which are commonly found in certain soils and can pose significant health risks if they enter a building.

The material is tough, tear-resistant, and reinforced, ensuring durability even in demanding groundwork applications. Additionally, its compliance with UK Building Regulations, BS 8485, and EN 13967 standards makes it reliable for ensuring gas-tight joints and installations, either through taping or welding, for long-lasting protection.

What is Novia Methane Pro 390 Gas Barrier & DPM?

Novia Methane Pro 390 Gas Barrier & DPM is a high-performance membrane designed to provide protection against methane, carbon dioxide, radon, and moisture ingress. It acts as both a gas barrier and a damp-proof membrane (DPM), making it suitable for use in building foundations where gas protection and moisture control are required.

What gases can Novia Methane Pro 390 Gas Barrier protect against?

Novia Methane Pro 390 Gas Barrier is designed to protect buildings from methane, carbon dioxide, and radon gases. It is an effective solution for sites where these harmful gases are present in the ground.

How do I install Novia Methane Pro 390 Gas Barrier & DPM?

Novia Methane Pro 390 should be laid on a smooth, flat surface, with overlaps of at least 150mm between sheets. Overlaps should be sealed using compatible tapes or welding to ensure an airtight and watertight finish. The membrane must also be connected to other gas-resistant elements like cavity trays or damp-proof courses for complete protection.

Is Novia Methane Pro 390 suitable for all building types?

Yes, Novia Methane Pro 390 can be used in both residential and commercial buildings. It is particularly useful in projects built on contaminated land or in areas with high levels of ground gases, offering reliable protection for foundations.
