ACOUSTIC MODULAR WALL SYSTEM
Akustak®, by Mute Group, is a patent protected, Part E compliant, acoustic modular wall system. Prefabricated and portable, it transforms interior wall construction into a rapid process of assembly; from 15 m2/per hour, whilst delivering outstanding airborne sound insulation performance.
Designed for materials optimisation and off-site construction, Akustak® eliminates waste, during manufacture and installation. Moreover, its unique demountable form, facilitates recovery and reuse, at the point of deconstruction.
Akustak® has been selected for Innovative Start-up Membership by the UK Green Building
How Akustak® Works:
Supporting frame installed
Wall plastered and/or decorated
An independent, twin-faced, modular acoustic wall system; typically installed to form new spaces/separations, including those where Building Regulations – Part E compliance is required (both in terms of purpose-built dwelling-houses and flats and dwelling-houses and flats formed by material change of use).
An independent, single-faced, modular acoustic wall system; typically installed in front of existing walls, for example, party walls between dwelling-houses and flats, where a significant increase in sound insulation is required.
A dual independent, twin-faced, modular acoustic wall system; typically installed to form new spaces/separations, where very high levels of sound insulation are required, for example, interview rooms, recording studios, test chambers, etc…
Akustak® Optimizing Project Efficiency
from Beginning to End.
Quick & Easy Access On-Site
Measuring ≤ 0.8 m2 / 25 kg, per module, Akustak® can be safely manually handled by one man (as per HSE guidelines), fitting through narrow staircases and corridors and inside elevators. Moreover, its intelligent, stackable design, minimises transport movements, at the point of delivery, and storage demands on-site.
Prefabricated and portable, Akustak® transforms interior wall construction into a rapid process of assembly; from 15 m2/per hour, subject to system selection.
Precision engineered, in a factory environment, Akustak® accurately interconnects, to form pre-specified wall sizes; minimising on-site errors and re-work.
Minimised Noise, Dust & Disruption On-Site
Manufactured off-site, Akustak® minimises trades and site activities; typically, installations require one to two fitters, a cordless drill and basic hand tools. This too, enhances health and safety standards on-site, including Covid-19 infection prevention and control.
Zero Waste to Landfill
Designed for materials optimisation and off-site construction, Akustak® eliminates over-ordering and expendable off-cuts, during manufacture and installation. Moreover, its unique demountable form, facilitates recovery and reuse, at the point of deconstruction.
Building Regulations Approved
Laboratory tested (in accordance with BS EN ISO 10140-2 & 717-1), Akustak® guarantees Building Regulations – Part E compliance. Aku125, for example, exceeds the requisite airborne sound insulation standards, for purpose built dwelling-houses and flats and dwelling-houses and flats formed by material change of use, by 4 and 6 dB(A), respectively.
Outstanding Airborne Sound Insulation Performance
Laboratory tested, across the product range, Aku125, Aku133 and AkuStudio deliver airborne sound insulation values of Rw 49, 43 and 62 dB(A), respectively.
Ply-lined, as standard, Akustak® enables secure surface-mounted fixtures and fittings, e.g. radiators, shelving units, TV brackets, etc…, without the need for reinforcements and/or wall plugs, whilst alternative fascias are available, e.g. plywood, rather than plasterboard, for greater robustness or decorative effect.
Akustak®, through its unique demountable form, facilitates recovery and reuse, at the point of deconstruction.
ExCel District Energy Centre
Case Study: Aku133 - Royal Docks, London
The ExCel District Energy Centre provides heat and power to the ExCel Exhibition Centre and surrounding area, through the use of Combined Heat & Power engines (CHP).
Airborne sound, emanating from these engines, was the cause of continuous noise nuisance complaints from the adjoining residential dwelling-apartments. Akustak® was specified to mitigate the problem, from the Energy Centre side.
It’s modular construction and manoeuvrability (particularly at height and within confined spaces), made Akustak® the perfect application for this logistically challenging project.
The modules were modified to suit the rigours of an industrial environment, including a fire-treated, impact resistant fascia; ensuring the installation is fit-for-purpose, for years to come.
Following the installation, sound levels, in the adjoining dwelling-apartments, were assessed to be between 23 to 30 dB (LAeq). On this basis, World Health Organization guidelines were successfully met, as stipulated by the local authority, i.e. in bedrooms at night, the guidance limit is 30 dB LAeq, 8h and 35 dB LAeq, 16h for living rooms and bedrooms, during the day.
