Radon Barrier Common FAQs

What is a radon barrier and why is it important?
A radon barrier is a specialist membrane designed to prevent harmful gases like radon and methane from seeping into buildings through the ground. It plays a crucial role in maintaining indoor air quality and protecting occupants from long-term health risks.

Where should a gas barrier be installed?
It should be placed beneath floor slabs and foundations to create an effective seal against gas infiltration. Proper installation ensures a continuous protective layer across the entire building footprint.

How do I know if my property needs one?
Certain areas have higher concentrations of underground gases, particularly radon. Checking government radon maps or conducting a site survey will help determine if installation is necessary for regulatory compliance.

What is the difference between a radon and a methane membrane?
Both provide gas resistance, but methane barriers offer a higher level of protection. A radon membrane will stop radon and damp, while a methane-rated product also protects against carbon dioxide and other ground gases.

Can these membranes be installed in any type of building?
Yes, they are suitable for residential, commercial, and industrial developments. They are often required in new builds, basements, and high-risk areas to meet UK Building Regulations.

What is the best way to seal overlaps and joints?
For maximum effectiveness, overlaps should be sealed using Novia Double-Sided Butyl Tape (minimum 50mm width) and Novia Single-Sided Aluminium Foil Tape (minimum 96mm width) to create a gas-tight seal.

Can radon barriers be welded instead of taped?
Yes, certain membranes can be welded for added security, particularly in large-scale or high-risk projects. Welding should be carried out by trained professionals and verified according to CIRIA C735 guidelines.

Are these membranes also suitable as damp-proof layers?
Yes, all Novia barriers comply with EN 13967 standards as damp-proof membranes, providing both moisture and gas protection in one solution.

Do they comply with UK regulations?
Yes, most of the Novia products meet BR211 guidance, BS 8485 standards, and are UKCA approved. They are tested to ensure compliance with industry safety and environmental standards. ALWAYS check though before ordering.
