Flexible Membrane

Definition - What does Flexible Membrane mean?

A flexible membrane is a selective semi-permeable material or barrier that prevents the transmission of certain substances, yet allows for the passage of others. Flexible membranes are used as a roof covering to prevent water penetration, while allowing air passage through the roofing material. This prevents water and carbon-induced corrosion.

Corrosionpedia explains Flexible Membrane

Some of the key benefits of using flexible membranes include:

  • Provides a long-term roof protection solution.
  • Micro-porous structure allows moisture to escape while providing long-term weatherproofing protection.
  • Reduced health and safety risk as it is solvent-free.
  • Lightweight material and therefore does not overload existing structures.
  • Excellent adhesion to a wide range of materials including felt, asphalt, lead, zinc, copper, glass, concrete and brick.
  • Adapts to roof movements due to its outstanding elasticity.
  • Can be easily applied by brush and roller with no mixing required.
