Acoustic Insulation

Noisestop Systems provide acoustic insulation slabs in your home to provide some quiet. Use DFM acoustic insulation to soundproof walls and increase sound insulation between floors and ceilings. Airborne sounds are greatly reduced when you use soundproof insulation to soundproof ceilings. Soundproof walls with DFM acoustic insulation to increase sound reduction between walls using sound insulation slabs.

Soundproofing insulation will increase the mass and density of a room—infill between stud walls and floor joists to increase the sound insulation between rooms. Acoustic insulation will reduce sound waves transfer between rooms.

When choosing which soundproofing insulation to use, the two main factors to consider are thickness and density. Ensure you have enough depth in the stud frame to incorporate the insulation. DFM acoustic insulation should not be compressed between plasterboard’s it could cause cracking along the joints. Please choose the right density of the sound deadening insulation you use, and we advise that mid-range density is sufficient for most domestic soundproofing applications. The soundproofing returns diminish the higher up the density you go. If you compare a 140kg/m³ slab to an 80kg/m³ slab, the performance would not be twice as high, but the cost would be.

  • Ceiling sound insulation
  • Floor sound insulation

DFM acoustic insulation is available in the following thicknesses and densities. The 25mm slabs are only available in the 100kg/m³ density. The 50mm, 75mm, and 100mm are available in the full density range of 45kg/m³ up to 140kg/m³.

  • 25mm – 100kg/m³
  • 50mm – 45, 60, 80, 100, 140kg/m³
  • 75mm – 45, 60, 80, 100, 140kg/m³
  • 100mm – 45, 60, 80, 100, 140kg/m³

Soundproof insulation for walls  to increase the sound insulation between rooms

Acoustic insulation is used to soundproof walls for high levels of soundproofing. Incorporate sound insulation inside stud walls and acoustic false walls for party wall soundproofing. Combining DFM with acoustic panels offers the highest levels of sound insulation for walls. Noisestop Systems supplies complete wall soundproofing kits that combine the best products to soundproof walls, floors and ceilings.

Acoustic insulation to soundproof between floors and ceilings

Use soundproof insulation to increase the acoustic performance of timber floors. Inserting DFM acoustic insulation between floor joists will increase the airborne sound insulation between floors. We recommend the 100mm DFM at 80kg/m³ for most domestic soundproofing applications. Separating floors that require acoustic floor insulation should use a minimum thickness of 100mm/45kg/m³. When you are soundproofing between floors and ceilings in your home, use the 100mm DFM.

DFM has a non-combustible Class O fire rating which will help separate floors and walls comply with Building Regulations.

Description

DFM acoustic insulation slabs, available in a range of densities from 45 to 140kg/m3. The standard product is supplied unfaced.

Application

DFM Slabs are used for a wide range of thermal and acoustic insulation applications in buildings, building services and industry.

Standards

DFM Slabs are made from non-combustible inorganic rock wool, defined as mineral wool in BS 3533: 1981 and are manufactured to a Quality Assurance System that complies with BS EN ISO 9001:2000.

Durability

DFM Slabs are odourless, non-hygroscopic, rot proof, do not sustain vermin and will not encourage fungi, mould or bacteria.

Environmental

DFM Slabs are free from CFCs, HCFCs, and any other material with ozone depletion potential in their manufacture and content and represent no known threat to the environment.

Thermal Performance

The thermal conductivity of DFM Slabs varies with density from 0.035 to 0.037 W/mK – see table below.

Fire Performance

DFM Slabs are 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 Regulations.
