How to Comply with Sound Insulation Building Regulations

Part E Building Regulations ‘Resistance to the passage of sound’ How to Comply

Every development in the UK now has a number of responsibilities to comply with building regulations. Part E Building Regulations ‘Resistance to the passage of sound’ covers sound transfer and sound insulation between attached dwellings, from party walls in connected houses to party floor and ceilings within a block of flats. Including:

  • E1 Protection against sound from other parts of the building and adjoining buildings
  • E2 Protection against sound within a dwelling-house etc
  • E3 Reverberation in the common internal parts of buildings containing flats or rooms for residential purposes
  • E4 Acoustic conditions in schools

Every dwelling must ensure the transfer of noise is in compliance with these regulations based on new build or conversion requirements.

So how can you ensure compliance with sound insulation building regulations when planning a development?

 
The steps below should help to ensure that when testing comes round at the end of the project, no unexpected failures or additional cost are incurred.

 
Use Project specific specifications

On the market are a number of standard constructions for wall and floor partitions, these specifications are normally high standard partitions. So we recommend working on a job specific specification.When using standard floor/wall constructions on a conversion project a number of issues can present themselves,

Flanking

A flanking path is a route through which sound can travel around a floor or wall partition, such as an old chimney breast running between different flats. Sound waves will always travel through paths of least resistance. If flanking paths are present the floor partition will become redundant and the sound will travel around the floor and result in a failure to meet sound insulation regulations.

When converting a property, you are working on an existing property which comes with a history. This history may include previous renovation projects, alterations and general wear and tear. If you are working from a clean slate and installing ‘off the shelf solutions’ you can generally disregard the potential ‘flanking paths’ the property already has,

Using project relevant specifications will ensure that all areas are assessed and eliminate the risk of a failure.

 Overspend

A number of the ‘off the shelf’ sound insulation systems will overcompensate to ensure that the system installed for the walls and floors will have allowances for multiple different scenario’s. Therefore when purchasing these systems you are paying additional for the consideration that the system may not be installed correctly etc, tailoring your own specifications will allow you to work with products you know and work with all the time. The consideration of your project can result in savings on both materials and time on site.
