Isolmant UnderSpecial 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, embossed and screen-printed on the top side, characterised by an improved and calibrated quality of the cellulation of polyethylene) joined on the underside to FIBTEC XF3 (special second-generation needle- punched fibre, produced to calibrated specifications for better noise reduction). It allows to obtain excel lent insulation against impact and airborne noise for
horizontal partitions.
Nominal thickness 10 mm.


Isolmant UnderSpecial Series R Fossil Free is specific for "floating screeds" in accordance with UNI 11516:2013, with any type of slab.
Particularly suitable for being laid under a finishing screed (two-layer solution), it requires the creation of a finishing screed at least 5 cm thick.
