What is Radon gas?
Radon is a radioactive gas that occurs naturally when the uranium in soil and rock breaks down. It is invisible and odourless thus difficult be detected. When radon is released from the ground into the enclosed spaces like homes it can accumulate to high levels and be a health risk.
THE RADON GAS BARRIERS ARE THE MOST EFFECTIVE SOLUTIONS TO PREVENT THE PRESENCE OF THIS GAS INTO HOMES.
ChovA can advise you on the best radon barrier to meet the requirement of a safer building. Two of our bituminous membranes are certified by the Spanish Environmental Radioactivity Laboratory of the University of Cantabria.
POLITABER AUTOADHESIVA ANTI-RADÓN
Membrane size 1×20 m sheet and 1.5 kg/m² of self-adhesive elastomeric bitumen (SBS), without reinforcement, interior removable silicone plastic finish and exterior finish with aluminum complex metal sheet and polyester film. Natural aluminum colour. Place adhered on the support primed with bituminous emulsion, and sealed in its longitudinal (> 8 cm) and transversal (> 10 cm) overlaps. Self-adhesive film, installation without a flame torch.
ChovAPLAST ALUM BV 30 E2
Plastomeric modified bitumen membrane size 1 m x 12 m of 2 mm thickness and 3 kg/m2 reinforced with an embossed aluminium and surfaced with plastic on both faces. Torch-on membrane to be fully or half bonded to the substrate.
POLITABER COMBI 40 ANTI-RADÓN
SBS modified bitumen membrane size 1 m x 10 m and 4 kg/m2 reinforced with a non-woven reinforced polyester felt and surfaced with plastic on both faces. Torch-on membrane.
POLITABER COMBI 48 ANTI-RADÓN
SBS modified bitumen membrane, size 1 m x 10 m and 4,8 kg/m2 reinforced with a non-woven reinforced polyester felt and surfaced with plastic on both faces. Torch-on membrane.
POLITABER PARKING 48 ANTI-RADÓN
Sheet of 1 m x 8 m and 4.8 kg/m² of elastomers modified bitumen, with nonwoven polyester felt armor, plastic interior trim and no perforating polyester felt exterior trim. Place by adhesion by blowtorch. In “Adherents” systems to support. The membrane acts as a barrier against gases such as Radon.
