Delta Radonsperre

Application

  • For use on sites with radon gas.
  • Protects against moisture, acting as a damp-proof membrane (DPM).
  • Suitable for horizontal applications.
  • For foundations and building walls.
  • Easy to lay out on large surface areas.

Description

A flexible, loose-laid gas barrier. It consists of a polyolefin blend forming a durable, tough sheet. It has an anti-slip profile on both sides to stabilize the sheet and optimize its adhesion to mortar.


The barrier offers protection from radiation of radon gas and moisture, even at extreme temperatures. The material will serve as a damp course under plaster floors.


Features and benefits:

  • Resistant to radon and carbon dioxide gas.
  • Extremely durable and tear-resistant.
  • Flexible and easy to adapt.
  • Resistant to extreme temperatures.
  • UV-stabilized.
  • Long-term protection.
