Moisture-variable vapour check Ampatex Variano 3 extra


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. Penetrations such as ventilation and electric pipes must be permanently sealed with Ampacoll BK 535.
