Soundproofing a floor helps reduce noise transmission between floors. The products required are determined by your existing floor build up you have and whether you’re looking for a reduction on impact or airbourne or maybe both.
Impact noise can come from loud footsteps or dropping/banging things on the floor and airbourne from talking, loud music or a television.
The types of floors that are often encountered are timber joists, floorboards and concrete floors. The products available will change depending on the floor type that you will be working on.
Whether it’s a refurbishment of a property or even a new build there are many products and solutions to be considered and the JCW team can offer advice on just what you need to do.
Domestic properties – flats and upstairs floors will almost always be timber joists & floorboards. These types of floors will always have a problem with sound transmission. Thankfully there are many products available to help with wooden floor soundproofing.
These overlay decks are laid onto of your existing floor and provide good airborne and excellent impact noise protection and is an excellent low cost choice for floor upgrades in lofts and extensions.
The JCW Acoustic Decks found via the link should be layed in the flowing way:
JCW Acoustic Decking floor panels are supplied in 2 standard board sizes dependant on the material.
All acoustic panels are laid as a floating floor (i.e. no mechanicalfixings). The boards must be dry and acclimatised at least 24hours prior to installation, this will minimise any expansion or contraction after installation.
The substrate or joists should be flat, dry, and free from all debris. Acoustic boards are best laid towards the end of the project to protect from general trades, high floor loadings and moisture leading to expansion.
The boards must be laid on to flat or levelled joists in the opposite direction of the joists. Direct to Joist boards can also be laid onto an existing sub-floor.
Any penetrations through the acoustic floor and beneath the separating ceiling must be correctly detailed and dealt with on a site by site basis.
Acoustic underlay goes underneath a top layer of flooring or carpet and is designed to reduce the transfer fo noise between floors.
A underlay product that JCW Acoustic Supplies offers is the Acoustic Impacta 4551 matting product to attenuate impact sound at the source.
Installation of this product is detailed underneath:
