Building protection pads contain plasticizers that can penetrate an existing waterproofing membrane over time.
This can lead to embrittlement of the insulation and thus possibly to failure (leakage).
The aluminum lamination on the back reliably prevents this softener migration and thus ensures perfect protection.
Thus, this special building underlay pad pad performs the following essential functions:
- the pad compensates for unevenness in the floor.
- it protects the insulation from punctual indentation by the pedestal.
- the aluminum lamination prevents plasticizer migration from the pad into the waterproofing membrane.
