Ampatex Variano 3 extra
Moisture-variable vapour check and airtight layer, lattice-reinforced
Lattice-reinforced, three-layer moisture-variable vapour check and airtight-layer made of polyamide and polypropylene.
- Ideal for injection insulation due to its high tear resistance
- Over 59 m sD value range for maximum protection in buildings where moisture levels are critical
- Excellent adhesive properties
Lattice-reinforced, three-layer moisture-variable vapour check and airtight-layer made of polyamide and polypropylene. Perfectly suited for flat roofs in timber construction; also for renovating pitched roofs with a dense outer skin. The membrane offers special protection when used on bare brickwork in winter. Ideal for injection insulation due to its high tear resistance.

Ampatex Variano 3 extra is applied as an airtight layer and moisture-variable vapour check for dry interior finishing and positioned on the warm side of the thermal insulation where it is stapled to the construction. Take care when positioning it that the membranes overlap by 10 cm and that the joints are tightly sealed with the enclosed system adhesive strip Ampacoll INT. Edge connections must be sealed with Ampacoll BK 530 or Ampacoll RA. Porous or dusty surfaces must be pretreated with Ampacoll Primax. Penetrations such as ventilation and electric pipes must be permanently sealed with Ampacoll BK 535 or Ampacoll Elektro u. Install sleeves. Humidity-variable materials can react to strong changes in ambient humidity. Consider shrinkage and expansion behaviour (e.g. conditioning on site, relief loops, mechanical securing, etc.).
