Underscreed Insulation

Isolmant Special

Second-generation Isolmant with embossed and screen printed upper side. Featured by a better and calibrate quality of the polyethylene cellulation.

Application areas

Isolmant Special is recommended for impact sound insulations of horizontal partitions. This product is suitable for applications between the levelling substrate and the screed in double-layer flooring. It ensures performance and quality over the time thanks to its physical characteristics. The finishing screed should be at least 5 cm (for Isolmant Special 3 and 5 mm) or at least 7 cm (for Isolmant Special 10 mm). Screeds with lower thickness should be reinforced by means of a suitable metal mesh or fibres.
