Soundproofing in new build construction projects can be a problematic task. There is no standard resolution, as each building has its own parameters which need to be considered. Architects, Contractors, Designers, and Customers need to fully comprehend how nuisance noises will affect a development project.
All accurate information and materials have to be carefully selected within the structural design, ensuring all new build developments are both fit for purpose and guarantee comfortable conditions. This is enforced by Part E of the building regulations (in England and Wales). Approved document Part ‘E’ was introduced in 2003 to ensure minimum standards for acoustic separation (soundproofing) between separate dwellings.
Part E of the building regulations applies to all newly built and properties divided into flats from this point on. These criteria ensure a level of separation that ensure two neighbours do not be unduly disturbed by ‘standard’ activity.
In order to comply with these regulations there are two methods: Robust detail and Pre-completion testing (PCT).
Robust Details: Was established in 2004 with the aim of helping architects and building contractors design and construct separating elements with confidence. Robust detail compliant products are proven solutions that don’t require testing after fitting.
Robust details have been pre designed to exceed building regulation requirements. A separating floor or wall construction can be selected from the Robust Detail handbook. These designs have undergone extensive testing to ensure they achieve an average of at least 5dB above current building regulations.
JCW supply products which are compliant to robust standard details FFT-1, FFT-2, FFT-3, FFT-4 and FFT-5.
PCT: If using the Pre-completion testing method, acoustics need testing after insulation to ensure they meet the building regulations.
The method of compliance on a new build which in turn affect design, material selection and specification procedure are dependent on the different source of noise.
Noise can be transmitted in new build developments by either airborne and impact sound sources. Airborne sources include speech, TV, music etc. Impact noise is the transmission of sound via the connection of different Materials to each other i.e. Footsteps on a floor of a house. The other sound source that can allow sound to transmit through a construction is flanking transmission which is where sound is transferred indirectly through adjoining structures.
Timber frame constructions are completed using load-bearing frames of treated timber, which make up the floors and internal and separating walls. Timber frame constructions can be effective in reducing impact noise sources and are a more cost-effective option than masonry cavity constructions.
The Building Regulations are a definitive set of rules for acoustic insulation performance for all types of new build construction projects. This includes residential, commercial, education, healthcare or industrial.
The most effective route for soundproofing a new build development is accommodating an acoustic/soundproofing solution at the earliest possible stage: the design process. Receiving JCW expert acoustic soundproofing advice, ensures ‘Part E’ compliance and will minimise risk of failures, consequently reducing the requirement for costly and disruptive remedial measures further into the project.
When planning a new build project Architects and Developers must consider the noise exposure of the development. Internal sources include building layout, separating walls/floor acoustic performance, reverberation measures and room. External factors or noise sources include external noises such as neighbours, road traffic, and other local influences.
JCW offers a wide range of acoustic products and solutions allowing an effective and efficient solution for new build developments and exceed compliance with the stated Building Regulations.
