Micoral NB Heat-Activated Self-Adhesive Vapour Control Layer - Icopal

Anderson Micoral NB Heat-Activated Self-Adhesive VCL

Anderson Micoral NB is for use as a vapour control layer in new build situations where the warm roof insulation in a bitumen or single layer system is being mechanically fastened. The membrane is used beneath insulation and safely controls the passage of internal water vapour through the roof structure. Since the membrane is adhered, it can provide a weatherproof temporary finish to the roof structure prior to the application of the final waterproofing system.

Features & Benefits

  • Quick, clean and simple to install.
  • Self adhesive side lap.
  • Savings in gas.
  • Suitable for all roof types.
