ISOLfon-BARRIER is a soundproofing membrane that increases the transmission loss of walls and ceilings, and especially in light/dry construction.
Thanks to their viscoelastic properties this soundproofing material, its high surface weight, its small thickness, its high mechanical resistance and flexibility, ISOLfon-BARRIER is one of the most practical sound insulation membranes for light and dry partitions that require a thin sound proofing material.
Fire behaviour: HF1 (UL94), SE (MVSS 302)
Temperature range: -30°C, +130°C (continuous use)
ISOLfon–BARRIER 5 Rw (C+Ctr) = 27 (-1,-3) dB
ISOLfon–BARRIER 10 Rw (C+Ctr) = 31 (-1,-4) dB
Drywall 2+2 plasterboards
On top of the Rw improvement by 5 dB, there is an additional 5-10 dB improvement at the frequency
range of 1500-4000 Hz.
That is the range of frequencies we commonly face at homes and offices.
