Conversions and Refurbishments
Older buildings were often constructed without sufficient consideration to the control of the transmission of sound between dwellings. In addition the level and types of domestic and external noise sources have increased significantly. Many buildings simply do not meet the requirements of both today’s legislation and peoples’ expectations of acceptable noise levels. In a conversion project it is necessary to establish whether proposed dwellings will have separating walls and/or floors. It is wise to carry out pre conversion sound tests to establish whether any existing floors and walls meet the performance requirements of the regulations. If they do and the floors / walls are unaltered then these tests may provide evidence of compliance. If not then Ecomerchant have a carefully selected range of tried and tested products which can be used to upgrade the acoustic performance of floors, walls and ceilings in conversions and refurbishment projects all designed to meet or exceed Building Regulations.
Performance requirements of the Building Regulations
Separating walls and floors should be built to meet the following requirements:
* The definition of a traditional building is a building or part of a building of a type constructed before or around 1919:
a) using construction techniques that were commonly in use before 1919: and
b) with permeable components , in such a way that promotes the dissipation of moisture from the building fabric.
Completed constructions are required to be tested by an accredited acoustician to demonstrate compliance with the Regulations.
A quick note on Flanking Transmission
Flanking transmission is where sound is transmitted indirectly between one room and another through adjoining parts of the structure rather than directly through the separating wall or floor. Often this will be through walls or floor joists, whichj means that direct contact in areas where sound can bypass the insulation need to be identified. It is important to identify potential flanking paths in advance as they can reduce the performance of the acoustic floor, wall or ceiling treatment. Typically this is why we suggest associated products such as perimiter strips when laying boards.
