Radon Gas Barrier Membrane - Monarflex RMB350

Monarflex RMB350 is a high quality loose-laid radon resisting membrane made from blends of virgin low density polyethylene (LDPE).

When used in a new building as part of the Necoflex RAM™ system, it provides an effective barrier to the passage of radon, air and moisture from the underlying soil.

Features & Benefits

  • Reinforced multi-layer membrane with high tensile and tear strength.
  • High radon gas resistance.
  • High performance moisture vapour barrier.
  • Enhances the overall air-tightness performance of a building.
  • Available in 4 metre wide roll (unfolded) which means quicker installation and fewer joints.
  • Fully compatible with the Necoflex RAM System.
  • NSAI approved.
  • Tear resistant and long lasting.
  • Radon & water barrier.
  • Width: 4m
  • Weight: 28.48kg

Monarflex RMB350 Radon Gas Barrier is a NSAI Agrément (Irish Agrément Board) approved radon gas barrier membrane.

It is an LDPE blown film membrane with a weight of 350g/m2.

This membrane is used as part of radon gas protection systems in buildings.

The membranes and the methods of jointing provide an effective barrier to the passage of radon gas, liquid water and water vapour from the ground.

When installed correctly and subject to normal use, this durable membrane will last the life of the building.
