Application / construction type
For constructions with existing ventilation or a diffusive external layer (e.g. dry interior finishing)
Roof renovation from outside
For constructions without existing ventilation and a diffusive external layer, e.g. flat roof. Proof of the hygric characteristics and increased processing controls (e.g. blower door test) required
Construction with a constantly high level of air humidity (approx. > 60%), such as indoor swimming pools, saunas, laundries, hotel kitchens.
Tips when laying: Dry interior finishing
Ampatex® Variano 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. Edge connections must be sealed with Ampacoll® BK 530 or Ampacoll® RA. Porous or dusty surfaces must be pre-treated with Ampacoll® Connecto. Penetrations such as ventilation and electric pipes must be permanently sealed with Ampacoll® BK 535.
- General requirements for the use of Ampatex® Variano:
- Fully functional airtight level
- Standard use of living space
In the case of exterior diffusion-resistant building components (e.g. flat roof), moisture-variable vapour checks make heavy demands on the planning side.
Additional requirements for processing with challenging technical implementation such as humidity (e.g. flat roof):
- Re-drying must not be hindered by panelling.
- Sufficient insulation thickness, compact and with no voids or spaces.
- Orientation, position and environment of the building component:
- Shade, also partial shade, e.g. by trees, solar power systems, nearby buildings and other aspects such as proximity to water as well as positions exposed to the weather are all problematic and must be examined on a case by case basis.
- Increased processing controls (e.g. blower door test)
