VELAPHONE

VELAPHONE is an acoustic membrane made of polyester felt and a black vapour barrier film. It is specially designed to be installed primarily on wood structures under self-levelling concrete coverings of 38 mm (1 ½ in) in thickness.


Benefits

  • Provides structural waterproofing while concrete is poured.
  • Prevents a too-rapid evaporation of water from the concrete to improve curing.
  • Resists crushing; preserves its acoustic properties.
