Isolmant BiPlus

High performance resilient layer made of 5 or 10 mm polyethylene Isolmant Special joined on the upper side to FIBTEC XT1 FIBRE-REINFORCED (screen printed anti-tearing fibre) and on the lowerside to FIBTEC XF1 (special needle-worked fibre produced according to specifications designed). It provides excellent impact sound and airborne insulation for horizontal partitions.


9 mm and 14 mm thicknesses available.



Isolmant BIPLUS is specific for floating screeds as provided by UNI 11516:2013 standards with any type of slab. As well as being suitable for use in two-layer solutions, the fibre-reinforced top layer can also be used as FIBRE-REINFORCED top layer can also be used as a top layer which guarantees the product’s high resistance to foot traffic and tearing, makes it particularly suitable for creating floating screeds in single-layer solutions.


Specific for horizontal structures with finishing screed at least 5 cm thick.

New release 2021

Fibre-Reinforced new top layer

Isolmant BiPlus today is even more "strong" and technological. On the occasion of its twenty-year presence on the market, Isolmant's Research & Development office has studied a new release characterized by the presence in the upper layer of an innovative fiber-reinforced fabric with a honeycomb process.


This revolutionary fabric increases resistance to tearing and expansion and also improves load distribution, for a product that is even more resistant during work on site and even more performing when subjected to the load of the screed.
