Viapol Techno Phase Polyester

Viapol Techno Phase identify a family of auto-thermoadhesive polymer bitumen membranes. The particular compound of the Techno Phase has been studied to soften and stick on the final support after the heating. It is sufficient to treat uniformly the external surface with the flame of a normal propane torch to activate and take to the softening the modified bitumen on the underside. The advantages offered by this kind of membrane are of absolut importance in all those circumstances where the flame is something that cannot be used on the support ( heat sensitive insulation materials, wood and other flammable materials ).



  • Vapour barrier: The application of the thermal insulation can be done in one solution,  using the adhesive opportunity by the softening of the external compound.
  • Application on thermo-sensitive insulation: It is possible to apply in one solution, a first layer on the insulation material (also fiberglass version) and another top layer. (its flame softening  will guarantee the adhesion of the Techno Phase due to the transmission of the heat to the first layer necessary for the activation of the thermo-adhesive mass directly in contact with the insulation material).
  • Undertiles waterproofing: Techno Phase in the slated version optimise and guarantees security to those applications, above all in presence of wooden structures.
  • Other applications: Waterproofing recover of existing bituminous layers, base layer for a solution of shigles.

Viapol Techno Phase is coupled externally to a thermo-fusible film in polyethylene that on the edge, is substituted with a removable strip  in polyprophylene siliconized. The lower surface of the membrane is coupled  with a removable film  in polyprophylene siliconized.

In the mineral version the external thermo-fusible film is substituted with the auto-protection af natural slate.
