Perforated reinforced base sheet to relieve water vapour pressure from under multi-layer torch-on membrane systems

Description

Proofex Torchseal A400 is a perforated membrane for connecting layers for waterproofing semi-adhesive systems, made of polymer-bitumen with reinforced fibreglass reinforcement. The 40mm diameter perforations are distributed evenly over the surface of the membrane providing 14% bonding area.

Uses

Proofex Torchseal A400 is used for spot bonding torch applied bituminous membranes particularly over substrates with relatively high humidity. It should be used as a first connecting layer to avoid the formation of blisters in waterproofing membrane applied on concrete which will remain visible to the eye. 
Proofex Torchseal A400 acts as a vapour diffusion layer if it is used as a connecting layer between a vapour barrier to be applied on a cement substrate of environments with a high level of relative humidity.
For restoration work, it is used to connect a new layer which will remain visible, with an old bituminous surface which has captured humidity.
The choice of using a spot bonded connecting layer should be subject to the careful evaluation by the planner of the roof and of the wind force present where the membranes will be applied.

Advantages

  • Cost effective
  • Quick to install
  • Allows the homogeneous distribution of spot-bonded adhesion zone
  • The finish layer is more resistant to the wind and is more stable to temperature variations than with other spot bonded methods
