Hello everyone, we are about to pour the screed. Now the question arises whether to lay the [Schweißbahn] or [Katifolie]. The screed height is 16 cm. What makes more sense?
The welding foil is laid on the base plate, then screed is applied on top; that's how it was explained to me. The screed height is 16 cm. Now the question arises whether we use the Katja sprint foil or the one for flaming. Maybe someone knows what this laying and flaming costs and which type of foil is suitable/better?
We do not have a basement and the slope (2.5 m height difference) is in the direction of the house, so we want to lay a foil to avoid mold formation later and for thermal insulation reasons. Otherwise, there is no special reason.
