Which Acoustic Floor Board is Suitable for my Project?

Acoustic Floor Boards

Identifying the acoustic floor board best suited for your project will depend on a number of key factors, including build type, floor construction, the type of room it is going to be installed in and the required performance. The following scenarios are designed to give you a better indication of the acoustic floor board that is most suitable for your project.

An Existing Apartment with Timber Floors

Existing timber floors typically lack sufficient mass to cope with impact noise. This makes it essential to install acoustic floor boards and other soundproofing components to deal with both impact and airborne noise transmission.

An acoustic chipboard laid on the sub-deck is a popular flooring choice for refurbishment timber floor applications. Acoustic chipboards are typically have minimal impact on the floor height, a popular thickness is 28mm.

To complete the soundproofing system acoustic chipboards should be installed in conjunction with acoustic flanking strips around the floor perimeter, soundproofing rolls between the joists, resilient bars and acoustic plasterboards fixed below the joists. It is important that all components are fit to achieve Part E Building Regulations.

For superior acoustic performance an acoustic dry screed board can also be installed instead of an acoustic chipboard. The boards are also typically 28mm thick, but the concrete like finish provides greater mass than an acoustic chipboards. This makes them more effective at eliminating impact noise transmission. Unlike acoustic chipboards these boards are also able to accept floor treatments such as a ceramic tiles directly. For superior all-round acoustic performance and product features dry screed boards are the stand out choice.

In scenarios where the ceiling below can not be replaced, for example there is a shop below, a direct to joist soundproofing board can be used. These types of boards feature multiple resilient layers and are thicker than acoustic chipboards to allow them to cope effectively with noise transmission.

A New Build Apartment with Timber or Steel Floors

As with existing timber floors, a lack of mass is a concern when soundproofing new timber and steel floors. The speed of building steel and timber developments makes them hugely popular in hotels and leisure facilities. In these applications a dry screed acoustic floor board is recommended due to their superior acoustic performance, the solid feel they give to traditionally “bouncy” timber floors and their extensive range of installation benefits. Part E Building Regulations also demands that new build projects provide better sound values after testing than existing buildings, making it recommended to install a superior acoustic floor board.

As with existing floors acoustic flanking strips should be installed around the floor perimeter, soundproofing rolls between the joists and a high performance acoustic ceiling below.

Existing or New Build Concrete Floors

Concrete floors offer greater mass than timber floors, making it less essential that the acoustic floor board provides additional weight to deal with impact noise transmission.

An acoustic chipboard or dry screed board combined with an acoustic flanking strip around the floor perimeter is suitable for this application. Although an acoustic chipboard solution is suitable, the extensive benefits of soundproofing dry screed boards makes them a more versatile choice for this application. These boards provide a more solid feel under foot and are also better suited to wet room applications.

Soundproofing Wet Room Floors

Bathroom and kitchen floors require careful attention when soundproofing. The acoustic floor boards must be able to cope with frequent contact with water. For this reason it is recommended that dry screed boards are installed in wet rooms, they are able to resist water effectively and accept floor treatments such as ceramic tiles directly. In contrast acoustic chipboards can be damaged by water ingress and must be covered with a damp proof membrane (DMP) to accept adhesive and ceramic tiles.
