KÄHRS LT ACOUSTIC UNDERLAY 2MM

Permanently elastic underlay material made of mineral fillers and polyurethane binders, this acoustic underlay was designed specifically for the installation (with single-sided fixation) under LVT floors with the scope to reduce impact sound and walking noise. Strong resistance to pressure and very good dimensional stability High water vapor resistance Improvement of the walking comfort (absorbing characteristics ) Excellent compression strength High Reduction of impact sound Excellent long-term walking sound reduction Special self-adhesive surface for efficient installations Suitable for underfloor heating, least possible thermal resistance Age resistance > 50 years Immediately walk-on-able Removable extreme time-saving and residue-free 100 % recyclable, odor and dust free TECHNICAL DATA Material: PU + mineral fillers + castor oil Type of format: roll 1 x 8m Thickness: 2 mm Impact Sound IS: 16 ± 2Db Reflected walking sound: up to 7% Compressive strength CS: 450 kPa Compressive creep CC: 50 kPa Punctual conformability PC : 0,79 mm Thermal resistance TR: 0.01 m2K/W Water vapor resistance SD: 75 m Residual indentation: <0.20 mm Reaction to fire: Bfl-s1
