Isolmant UnderSpecial BiPlus Serie R Fossil Free

High-end resilient layer made of polyethylene Isolmant Special Series R Fossil Free (completely sustainable and from renewable sources, in green colour, characterised by an improved and calibrated quality of the cellulation of polyethylene) joined on the upper side to FIBTEC XT1 FIBRE-REINFORCED (screen printed anti-tearing fibre) and on the lower side to FIBTEC XF1 (special needle-worked fibre produced according to specifications designed). It provides excellent impact sound and airborne insulation for horizontal partitions.
Nominal thickness 11 mm.


Isolmant UnderSpecial BiPlus Series R Fossil Free is specific for the creation of "floating screeds" in accordance with UNI 11516:2013, in the presence of any type of slab.


Isolmant UnderSpecial BiPlus Series R Fossil Free requires the creation of a finishing screed at least 5 cm thick.
