Protection from noise contributes towards the quality of life, health, productivity and the internal environment in offices, hospitals, schools and non-domestic buildings of all types across the built environment.
Many activities of modern life increase the level of nuisance noise we are exposed to, road and air traffic noise for instance, and they can have an adverse effect on the internal activity and comfort of a building`s occupants.
Additionally noise breakout from a building needs to be prevented, especially when the business activity generates high noise levels which can disturb both neighbour`s and the local neighbourhood.
Schools, hospitals, offices, factories and many other types of buildings have very specific acoustic requirements and building regulations, planning consents or client`s demands often stipulate what noise levels are acceptable based on the activity and relationship of adjacent areas and buildings.
For instance, in schools the impact of rain noise has to be taken into account to ensure that the learning environment is not adversely affected by the loud “drumming sound” that can occur during periods of heavy rainfall.
Therefore, it is essential to consider the method of construction for the building fabric at an early stage in the design and procurement process especially when the specified acoustic performance is of equal or greater importance than that of the thermal performance.
One commonly used solution is the installation of glass and rock mineral wool insulation within built-up metal roof and wall systems which can quite easily deliver very high levels of acoustic performance. A typical standard built-up metal system can provide a Sound Reduction Index (SRI) of up to 39 Rw dB compared to approximately 25 Rw dB for a typical rigid foam composite roof or wall construction.
Specialist acoustic systems usually comprised of a glass mineral wool quilt, rock mineral wool slab and a perforated liner sheet can deliver an SRI of 52 Rw dB and beyond. Therefore, even the most demanding acoustic (and thermal) performance requirements can be met by the specification of high performance built-up metal and wall construction systems.
