Underscreed Insulation

Isolmant UnderSpecial EVO

Product made of 1,5 mm High Density Isolmant with the lower side bonded to FIBTEC XF2 (special needle-punched fibre produced according to specifications conceived to provide a better noise reduction). Isolmant Underspecial EVO_BV bonded to a HDPE vapour barrier available on request (version BV).

Application areas

Isolmant UnderSpecial EVO is specifically conceived to optimise the acoustic performance of floating screed made of selflevelling compound. The density and the low thickness of these screeds (no less than 3 cm) cause vibration phenomena at high frequencies and Isolmant UnderSpecial EVO is designed to avoid this effect. In addition, thanks to its top adhesive fabric, Isolmant UnderSpecial EVO provides a perfect sealing for fluid castings screed.
