Thermal Conductivity: 

• 18mm P5 Chipboard: 0.15 W/mK
• 10mm PET: 0.16 W/mK

Thermal Resistance: 

• 22mm P5 Chipboard: 0.15 m² K/W

The higher the figure for airborne, the better the performance. The lower the figure for impact the better the performance.

Direct to joist airborne results

Without soundproofing 41dB

With Noisedeck 28 laid directly to the joist, 100mm acoustic insulation between joists, Soundbreaker bars and two layers of 12.5mm acoustic plasterboard 56dB

Direct to joist impact results

Without soundproofing 79dB

With Noisedeck 28 laid directly to the joist, 100mm acoustic insulation between joists, Soundbreaker bars and two layers of 12.5mm acoustic plasterboard 55dB

Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear. Decibels Explained.

• • Install directly over the floor joist or as an overlay system
  • Interlocking T&G edges require wood glue to secure them. No mechanical fixing is required
  • Lay in a brick bond pattern
  • Ensure all joins are supported
  • Ensure the flooring is isolated from the walls using the perimeter isolation tapes

  Before you start fitting the Noisedeck boards, check the area for debris and nails. Make sure the area is clear before commencing with the installation.

  1. Fit the isolation tape to the perimeter of the wall.
  2. Start at the furthest point in the room and lay the first Noisedeck perpendicular to the joist, butting the edge into the isolation tape.
  3. Apply wood glue along the edges of the boards as you lay them in a brick bond pattern.
  4. A joist should support all joins; additional noggins may need to be installed to support the edges.
  5. Once the boards have been laid, install the skirting and trim off excess isolation tape.
  6. Allow 24 hours after completing the installation before commencing any further work on the floor.

  We advise that all wall partitions be built before installing the Noisedeck boards.

  Kitchens and bathrooms should be fitted onto a suitable platform and not directly onto the Noisedeck boards.

  Most floor finishes are suitable for laying directly over Noisedecks. If you are laying tiles, we recommend using suitable flexible adhesive and grout. If additional strengthening is required, sheet materials can be laid over the Noisedecks.

  We recommend installing the Noisedeck boards with a suitable ceiling system to meet Part E Regulations. For the highest level of soundproofing, combine with the AcoustiClip Timber Ceiling System.

Impact noise through floors refers to the sounds generated by impact or physical contact on a floor surface that transmits to the space below. This could be footsteps, dropping objects, dragging furniture, or any action that causes vibrations and sound transmission through the floor’s structure.

Soundproofing materials, acoustic underlays, and floating flooring options are used to reduce the impact noise that travels between floors. Our Noisestop F7 Plus and Noisestop Acoustic Underlay are the best soundproof mats. The Noisedeck range of interlocking floating floors includes the Noisedeck 32, a direct to joist system and the Noisedeck 18T, a floor overlay system.

Installing soundproofing to the floor will give you the best results in reducing impact noise. However, ceiling solutions are also available to reduce impact noise from below.

Airborne noise refers to sound that travels through the air, like voices, music, or TV noise. To soundproof against airborne noise, you add mass and absorption materials to the floor.

Materials such as acoustic insulation and soundproof mats all help reduce airborne sound transfer between floors. The Noisestop F7 Plus is our highest performing acoustic underlay. Acoustic insulation DFM, 100mm between floor joists, is another way of increasing the mass and absorption of wooden floors.

You can lay the carpet directly onto acoustic underlays. You might use them in conjunction with a traditional carpet underlay for added comfort.

If the flooring you are using is below 14mm thick and you are using one of the acoustic underlays, you would need to use a resilient layer over the soundproofing to support the floor finish. Flooring over 14mm, such as engineered flooring and natural wooden floors, can be laid directly over the underlays.

Interlocking floors in the Noisedeck range already have a suitable base for any floor finish, so they do not require further treatment.

When installing soundproofing for your floors in these spaces, avoid directly placing kitchen units, baths, sinks, or toilets onto the soundproofing. To maintain consistent floor heights, employ a plinth beneath these items to ensure everything stays at the proper level.
