Part E Acoustic Building Regulations
Cellecta's refurbishment and conversion solutions guide demonstrates how a
number of commonly found separating floor and wall constructions can have
their acoustic performance upgraded with proven, cost effective treatments that
will exceed the demanding acoustic legislative requirements.
What do the Building Regulations require?
To comply with current legislation, all separating floors and walls must be constructed in such a way as to
achieve minimum prescribed acoustic values. Tests must be carried out by an accredited acoustic engineer
to demonstrate compliance.
Refurbishment and conversion projects
Each construction element adopting exactly the same construction must be precompletion tested (PCT) by an
accredited acoustician at a rate of 1:10.

Historic Buildings
With some historical buildings undergoing a material change of use it may not be practical to
achieve the prescribed sound performance values. In these cases, Building Control bodies
should be satisfied that everything reasonable has been done to improve the sound
performance of the structure. PCT is normal y required and the results submitted accordingly.
Airborne sound tested to BS EN ISO 140-4 1998
Selecting the correct acoustic solution
Each project's acoustic characteristics are different and should be assessed on an
individual basis. Before a solution can be proposed, a number of important facts
need to be established:
1 Is the proposed development deemed to be new build or change of use (including refurbishment)?

2 What element(s) are to be addressed: walls floors ceilings?

3 What is the construction makeup of all the walls, floors and ceilings?
4 Is the existing ceiling to be retained or upgraded?
5 Are there restrictions on the height of the floor finish and ceiling depth?
Once the information has been gathered, either select one of the solutions given on pages 4 16, or should
the construction not be detailed, contact Cellecta's technical team on 08456 717174 with the specific
construction details.
