Isolmant TOP

Insulating underlay made of thermally conductive viscoelastic material, specific for floating installation of wooden or laminate flooring onto underfloor heating. This product is coated by an aluminised PET film to prevent rising moisture.


The Isolmant Top acoustic system is designed specifically for floating installation of laminate flooring, wooden flooring and other types of hard flooring. A high quality system to reduce impactive and reflected noise. Isolmant TOP has been developed to protect the interlocking devices of these floors even when subjected to high loads. The use of Isolmant Top is specifically indicated in applications with underfloor heating systems, including those with low inertia/low thickness.
