High density acoustic insulation slab sound insulation for
walls, floors and ceilings.
Most soundproofing projects need acoustic insulation to reduce the transfer
of airborne noise. DFM acoustic insulation is used in wall, floor and ceiling
applications that require effective sound insulation. DFM insulation should be used for
blocking and absorbing sound that would normally pass through ceiling cavities,
stud walls and wall cavities. DFM is available in a range of densities, from
45kg/m³ up to 140kg/m³, Building Regulation requirements for separating floors
stipulate a density of 45kg/m³, for most domestic applications we would
recommend sound insulating with the mid density slabs at 80kg/m³.
This density represents the
best value for money spent, compared to the overall noise reduction, the
the density the better the performance, however the sound reduction
reduces as you go up in density. Our wall and ceiling soundproofing
the 80kg or the100kg density slab to ensure high levels of
soundproofing. DFM has a non cumbustible fire rating and will also
increase thermal insulation.
DFM Slabs are classified as non-combustible to BS 476:
Part 4: 1970 (1984) and Euroclass A1, Class 1 Surface Spread of
Flame to BS 476: Part 7 1997 and Class ‘O’ to the Building
DFM acoustic insulation slabs can be cut with a hand saw to fit any shape.
DFM does not need mechanical fixings as the slabs will friction fit between
studs and floor joists, cut the insulation slabs slightly wider than the opening to ensure a tight fit.
