Durabella Sound-Check Timber Flooring Systems have been developed for use on timber joisted floors to meet the new acoustic performance standards of Building Regulations Approved Document E 2003.


Airborne and impact sound has become an increasingly pressing problem, particularly when performance criteria can change dramatically with different floor constructions and ceiling detail or when a residential property is situated over a commercial outlet.


Sound check systems are an effective and versatile solution to this problem, as the system configuration can be adapted to suit specific needs.  Durabella Sound-Check Timber Flooring Systems are ideal for refurbishment or conversion projects as they can be applied to the existing timber floors, without the need for lifting boards to install insulation.
