Soundproofing a Bathroom
Soundproofing a bathroom requires careful consideration for the high levels of water and moisture that are present in these environments. Selecting the wrong solution can result in damaged floors and significant repair costs to resolve. In addition to meeting Part E Building Regulations it is important to soundproof bathrooms to reduce the noise of running water, pipes and foot traffic.
Timber Floor Bathrooms
To prevent any potential issues with water and moisture it is recommended that timber floor bathrooms are soundproofed using a dry screed acoustic floor board. Acoustic chipboards may provide the necessary soundproofing performance, however they are vulnerable to moisture ingress resulting in damaged floors and significant cost to rectify. It is also not recommended to lay typical wet room floor finishes such as ceramic tiles to acoustic chipboards as For maximum convenience and acoustic performance a dry screed system offers significant benefits in these applications. Ceramic tiles are a popular floor finish for bathrooms and it is possible to install them directly to dry screed boards.
When installing acoustic flooring it is important that acoustic flanking strips are installed around all sanitary ware in addition to the entire floor perimeter. Failure to do so can compromise the acoustic floor as sound and vibrations are able to transmit through the furniture that is fixed directly to the floor.
Concrete Floor Bathrooms
Bathrooms featuring concrete floors are naturally equipped to cope with water and moisture. The mass of concrete floors also enables them to deal with airborne noise effectively, which means there needs to be a greater emphasis on eliminating impact noise.
If a screed finish is adopted for a concrete floor it is suitable to install a polyethylene under screed soundproofing solution. This solutions moisture resistant properties make it perfectly suited for these type of applications. Featuring an acoustic flanking strip and joining tape the system is effective at containing the screed and isolating it form the floor.
If an acoustic floor board is installed on a concrete bathroom floor, it is recommended that a dry screed board is adopted. The boards ability to cope with moisture and accept ceramic tiles makes it the most suitable choice for this application. As with timber floors chipboard based acoustic floor board could be damaged by water in this application.
