Lafarge Acoustic Floor is a high performance sound insulation that can be adhered to delicate ceiling structures which can also entertain added fire performance by using 15mm Megadeco or Firecheck wallboard. Effective sound insulation requires very close attention. Lafarge Acoustic Floor is one of the simplest high-performance sound insulating floor systems available. It has wide applications in new-build, conversion, and particularly remedial work, where an improved sound rating is required. Lafarge Acoustic Floor adds only 6mm to the overall floor thickness, so it can be accommodated in existing buildings without expensive alterations to internal joinery. A free-floating system that adds both mass and sound absorption to achieve exceptional airborne and impact sound insulation. Lafarge Acoustic Floor is suitable as a separating floor between dwellings and can provide 60 minutes fire resistance, in addition to sound insulation of between 62dB and 65dB.
