SIF - Silent floor channels can be used to improve both impact and airborne noise transference through timber joist floors and floorboards. Mainly used when client wants to keep original floor boards as final floor surface .The metal channels are installed to the existing joist and the isolation strip decouples the floorboards from the current structure, thus creating a floating floor.
The transfer of impact noise through floor structure to the room below, for example impact noise from footfall or furniture movement, is reduced due to the integral neoprene strip located within Floor Channels An existing structure can be improved, in terms of both fire and acoustic performance, without requiring extensive alteration, even where access is available from above only. Benefits Provides a significant uplift in acoustic performance making it an ideal upgrade for transforming a non-performing floor to one that is Building Regulations compliant

Adds only 7mm to the existing floor height.
Acoustic & Fire Performance: Sound insulation airborne: 54 - 63 (Rw dB)
Sound insulation impact: 63 - 55 (Lnw dB)
