Installation information

Isolmant UnderSpecial EVO installation

Isolmant UnderSpecial EVO can be installed instead:

 

1) Before pouring the finishing screed, directly on the structural floor, which must have a flat, even surface.

 

2) Above the levelling layer for the systems, which must be made using suitable materials and recipes in order to guarantee adequate mechanical support and a flat, even surface. 

 

3) Below the underfloor heating/cooling panels and above the plant levelling layer, which must also be made using suitable materials and recipes in order to guarantee adequate mechanical support and a flat, even surface.

 

In all cases the sheets of Isolmant UnderSpecial EVO must cover the entire surface of the floor and must be carefully joined and sealed with Isolmant Nastro Telato. To avoid acoustic bridges, the use of Isolmant Fascia Perimetrale is recommended, to be laid along the entire perimeter of the room without interruption.
