Processing instructions

Application / construction type

Uncomplicated
For constructions with existing ventilation or a diffusive external layer (e.g. dry interior finishing)

Uncomplicated
Roof renovation from outside

Challenging
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

Prohibited
Construction with a constantly high level of air humidity (approx. >  60%), such as indoor swimming pools, saunas, laundries, hotel kitchens.
