We supply materials that form a protective barrier against radon gas, generally known as “radon barrier membranes”, suitable for installation both in buildings under construction and in existing buildings. We distribute a complete range of radon membranes, suitable for every type of situation.
The RADBAR PLUS system consists of a radon barrier membrane 400 microns thick (1600 gauge), made up of two layers of reinforced polyethylene, an internal polyester fibre mesh, and a 0.02 mm aluminium layer. A butyl tape is used to seal junctions between membrane sections and building elements against radon, and a duct/adhesive tape is used to seal overlaps.
With a radon transmission of 1 × 10-13 m2/s, a figure 100 times lower than the maximum transmission specified by CTE DB HS-6, the RADBAR PLUS system provides very high protection against radon ingress into buildings. It is recommended for homes and residential buildings, or any project where the goal is not only to comply with the regulations but to reduce radon as much as possible.
Thanks to its waterproof characteristics, the RADBAR PLUS system can reinforce or even replace damp-proof membranes or conventional gas or volatile membranes such as methane or CO2 barriers.
The radon barrier membrane of the RADBAR PLUS system (NOVIA PRO 390) is a non-bonded sheet that is easy to install. We recommend reading the Installation guide beforehand.
Butyl tape is an essential material for the correct installation and airtight joining of radon membranes. RADBAR double-sided adhesive tape is made of butyl rubber, specially designed for airtight sealing of overlaps between radon membranes. Roll dimensions: 25 m × 15 mm × 1 mm.
Tear-resistant adhesive tape specially designed for final sealing of overlaps between radon membranes, preventing ingress of dust, sand, and dirt that could affect the effectiveness of the butyl tape. Roll dimensions: 50 m × 75 mm.
Aluminium tape with adhesive on one side, designed for airtight sealing of penetrations such as pipes and other building elements. Roll dimensions: 46 m × 75 mm.
Hand-mouldable butyl rubber tape with adhesive on one side, ideal for airtight sealing of small-section penetrations such as electrical cables. Roll dimensions: 5 m × 50 mm × 2 mm.

The RADBAR 400 system consists of a radon barrier membrane 400 microns thick (1600 gauge), manufactured from a blend of high-quality polymers with high tear resistance, a butyl tape to seal junctions between membrane sections and building elements against radon, and a duct/adhesive tape to seal overlaps.
The RADBAR 400 system is recommended for workplaces and industrial facilities in Zones 1 and 2, as well as residential buildings in Zone 1.
This is a non-bonded radon barrier membrane system that is easy to install. Thanks to its waterproof characteristics, the RADBAR 400 system can reinforce or even replace damp-proof membranes.
There are two radon barrier membrane options for the RADBAR 400 system: Powerbase Lowperm and Toughsheet. Both sheets are equivalent in their characteristics, colour, and dimensions.

The RADBAR 300 system consists of a radon barrier membrane 300 microns thick (1200 gauge), manufactured from a blend of high-quality polymers with high tear resistance, a butyl tape to seal junctions between membrane sections and building elements against radon, and a duct/adhesive tape to seal overlaps.
The RADBAR 300 system is recommended for workplaces and logistics/industrial warehouses in Zone 1, with a clear height on the ground floor of 9.5 metres or more.
This is a non-bonded radon barrier membrane system that is easy to install. Thanks to its waterproof characteristics, the RADBAR 300 system can reinforce or even replace damp-proof membranes. We recommend reading the Installation guide beforehand.
