Vetrofor

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
