Rhinoplast Evolution Gas Barrier

Rhinoplast Evolution is a high specification co-extruded multi-layer barrier specifically developed for use on construction sites contaminated by Volatile Organic Compounds, Hydrocarbons and other ground gasses such as Methane, Radon and C02.

The product is 14 layers and contains 2 layers of gas barrier polymer (EVOH) to offer exceptional performance and prevent the ingress of dangerous gasses into buildings. It is manufactured using the latest co-extrusion technology and cannot de-laminate. The product will also act as a damp-proof membrane.

The membrane is manufactured using high performance engineering polymers to give exceptional strength and does not require reinforcement. It can be installed by the use of sealing tapes or can easily be welded.
