RADON FLOOR
RADON FLOOR is a radon and vapour barrier certified by the SP Institut that prevents radon gas from infiltrating the building envelope.
With double reinforcement, it ensures great durability.
It consists of a double layer of low-density polyethylene with reinforcement mesh and high-density polyethylene reinforcement.
It is applied to the inside and outside of walls, in contact with the ground.

Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
Recommended use: It consists of a double layer of low-density polyethylene with reinforcement mesh and high-density polyethylene reinforcement. It is applied to the inside and outside of walls, in contact with the ground.
Installation: Unroll the membrane over the designated surface.
Fix the membrane to the substrate using butyl tapes such as SUPRA BAND or BUTYL BAND.
Further details regarding installation can be found in the specific instructions provided by the supplier.
