Sisalex 303 is applied as an airtight layer and 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. Ampacoll DT acrylic tape represents an installation aid on underlying structures that cannot be nailed. Application of the interior lining serves as the final fastening step. Edge connections must be sealed with Ampacoll BK 530 or Ampacoll RA. Porous or dusty surfaces must be pre-treated with Ampacoll Primax. Penetrations such as ventilation and electric pipes must be permanently sealed with Ampacoll BK 535 (50 mm). Use Ampacoll Primax as a primer on porous, dusty or rough surfaces.
