ProctorPassive Wraptite SA

Protor Passive Wraptite-SA is a self adhering airtight and vapour permeable membrane for wall and roof applications.

It combines the best properties of a vapour permeable membrane and a self adhesive water and air barrier in one innovative self-adhering product. Use of highly vapour permeable self-adhesive membranes decreases installation times when compared to mechanically fastened membrane systems and is suitable for residential, commercial and high rise buildings.

Continuous contact of the membrane to the sheathing by even distribution of stress over the entire bonded surface allows better resistance to wind pressures and elimination of stress point concentrations.

Scope of Use

Proctor Passive Wraptite SA can be installed on new and existing buildings and it is suitable for roof and wall applications for residential, commercial and high rise buildings.

Proctor Passive Wraptite SA's high vapour permeable peel and stick products used full coverage in pitched roofs and walls allows excellent drying capacity for assemblies wet during construction and from typical in service leaks over the life-time of the building.

Proctor Passive Wraptite SA can be installed over rigid air barrier, replacing tape and flexible underlay. It offers minimal mechanical fixings and provide greater integrity of installation and system. 

Multiple substrate compatibility:

  • Exterior Gypsum Sheathing
  • Aluminium (painted or mill finish)
  • OSB
