Acoustic Insulation

Dense Fibre Matting (DFM) Acoustic Insulation Slab

Noisestop Systems provide acoustic insulation slabs to improve sound insulation in your home. Use DFM acoustic insulation to soundproof walls and increase sound insulation between floors and ceilings. Airborne sounds are greatly reduced when you use acoustic insulation to soundproof ceilings. You can soundproof walls with DFM acoustic insulation to improve the sound insulation for walls when you incorporate acoustic slabs.

DFM acoustic insulation is avaialble in the following thicknesses.

25mm DFM | 50mm DFM | 75mm DFM | 100mm DFM

  • Sound insulation for walls
  • Ceiling sound insulation
  • Floor sound insulation

Acoustic insulation to soundproof walls increase the sound insulation between a wall

Acoustic insulation is used to soundproof walls for high levels of soundproofing. Incorporate 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. We supply complete wall soundproofing kits that combine the best combinations of products to soundproof a wall.

Acoustic insulation to soundproof between floors

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 separating 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 which complies with BS EN ISO 9001:2000.

Durability

DFM Slabs are odourless, non-hygroscopic, rot proof, do not sustain vermin and will not encourage the growth of 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 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 Regulations.
