Special RADON Barrier

A specialized, 6-layer floor underlay, tested at the Institute of Nuclear Physics of the Polish Academy of Sciences and Aalborg Universitet København, equipped with an integrated radon barrier with efficiency far exceeding European standards, including “SBi 2016:21, Lufttæthed af materialer til radonsikring – Testmetode”. It serves to protect residential buildings against penetration of radioactive RADON gas through the floating floor layers. Compliant with all the high EPLF requirements for floors loaded with heavy traffic. This product is a part of Anti-RADON System and requires Special RADON Tape to ensure its full functionality

• Closed cells HDPE foam used for installation of laminated and engineered floating floors.
• Suitable for floor heating.
• For high demands on pressure stability under heavy loaded floors.
• Integrated 6-layer moisture and RADON barrier with overlap and butyl tape for fast installation and perfect protection against RADON.
• Radon Transmittance (P)<6,8*10-11m/s; Radon Resistance (Z)>1,5*10-10s/m.
• Radon Permeability (k)<1,4*10-13m2/s.
• Tested according to “SBi 2016:21, Lufttæthed af materialer til radonsikring – Testmetode”, Test Report SBi 2018:06.
• Can be laid easily and quickly, since it is always flat and has a slippery surface.
• Very high material density.
• 100 % recyclable, CFC and HCFC free.
• Ecologically friendly.

All data are based on our experience and careful investigations. The diversity of the materials used, as well as the different construction site and processing conditions, can not be examined or influenced by us in detail. The quality and function therefore depends on the expert site evaluation and product use. In case of doubt, carry out your own tests or seek advice on our application technology. When processing, please observe the rules of technology as well as the manufacturing specifications of the building materials involved and constantly changing state of technology.

Approx. 1 year, in the temperature form 0 to 25°C , protecting from direct sunlight or other weather influences.

Unroll underlay over subfloor with vapor barrier layer facing up and with individual rows abutting to one another and seal the joints with integrated overlapping and butyl tape to ensure complete sealing of the layer. Directly follow the application instructions of the Special RADON Barrier system available in the downloadable materials.
