dB Part E System 2 (Timber Floor)

The dB Part E Systems are our tried and tested acoustic floor and ceiling build-ups that are tried and tested to achieve and exceed Part E of the Building Regulations. Every system also has a wealth of test data proving its performance. To find this, look in the Technical Data section below, where a number of test reports can be downloaded and compared.

The dB Part E System 2 is for an existing building with timber joists and brick walls. This is your typical conversion specification for traditional existing UK buildings.

This is an advanced specification based on dB Part E system 1, but with the introduction of dBoard into the ceiling instead of soundbloc plasterboard. The specification is low profile yet robust and able to receive all flooring types. System 2 is very straightforward. From the existing timber joists and either new 22mm chipboard or existing timber floorboards, install our dB Matting 15mm over the existing floor. To the underside of the joists, install Maxi Resilient Bars and 2 layers of board. This includes 1 layer of dBoard and 15mm soundbloc plasterboard. Seal the perimeter with acoustic sealant and skim plaster to finish.

Take a look at the test data in the technical downloads below that have a variety of results based on whether there is an acoustic floor included. Some data is with no acoustic floor and just the ceiling specification.
