Description: Perforated bitumen-polymer membrane with reinforced glass tissue mat to use as an intermediate ply in partially bonded built-up waterproofing applications. Upper and lower faces are coated with adhesion-inhibiting polyetylene film.



Fields of application:

  • Vapor control layer
  • Venting sheet
  • Spot-bonded waterproofing membrane is able to distribute the stresses caused by thermal expansion and substrate settling more uniformly
  • The spaces formed between Vetrofor membrane and the waterproofing ply relieve the vapor pressure that  builds up as trapped water evaporates
  • Using Vetrofor under the waterproofing ply is essential when old roofing systems must be renewed and rejuvenated without removing them
