Akustak®: Committed to Climate Action

As longstanding members of the UK Green Building Council (UKGBC), Akustak® actively supports their mission to radically improve the sustainability of the built environment; helping transform the way it is planned, designed, constructed, maintained, repurposed, & operated.

Designed for Sustainability & Circularity

The development of Akustak® was guided by WRAP's Designing out Waste: A design team guide for buildings, & the following 5 key principles:

1. Design for Reuse & Recovery: Akustak®, through its unique, demountable design, is fully reusable, whilst the following features facilitate a diversity of (re)applications:

  • Dimensional flexibility

  • High fire safety rating (UKAS-accredited)

  • Interchangeable fascias

  • Option for service penetrations

2. Design for Off-Site Construction: Akustak® modules are precision-engineered off-site, in the UK. This, in combination with their portability (measuring < 0.8 sq/m / 25 kg), radically reduces staff hours on-site, with systems assembled by one fitter (as per HSE guidelines), from 15 sq/m per hour.

3. Design for Materials Optimisation: Akustak’s constituent parts are dimensionally coordinated, as per the standard unit size of the materials they’re sourced from; minimising expendable off-cuts during manufacture & installation.

  • Example A: the Akustak® SoundBloc fascia is dimensionally coordinated with a 1200 x 2700 mm gypsum board, such that each sheet provides four facias, with an overall waste level of 0.74%.

  • Example B: Akustak’s internal cavity, across the product range, is dimensionally coordinated with a 600 x 1200 mm insulation slab, with an overall waste level of 0%.

4. Design for Waste Efficient Procurement: Akustak® was designed to mitigate waste generation on-site. It serves as a resource efficient alternative to a construction industry staple: the timber stud wall.

Timber stud wall construction is innately wasteful, particularly in its propensity to generate unusable off-cuts.

  • Example: where studs are set at 600 mm centres (for compatibility with standard 1200 x 2400 mm gypsum boards), this reduces the cavity width (between studs) to c.555 mm. As such, standard 600 x 1200 mm cavity insulation slabs need to be trimmed to fit, resulting in a c.45 x 1200 mm off-cut, and, potentially, an overall waste level of c.7.5%.

Akustak®, through dimensional coordination, eliminates such incompatibilities between component parts, whilst its modularity minimises on-site errors & re-work; a further cause of considerable waste.

5. Design for Deconstruction & Flexibility: See Design for Reuse & Recovery and Design for Off Site-Construction.

Additionally, Akustak's simple method of (dis)assembly, makes deconstruction & flexibility a more feasible outcome, even when the connection between the original client/designer & the ultimate beneficiary becomes very remote, for example, when buildings are sold & re-sold over time.

Akustak®: Minimising its Contribution to Climate Change

Akustak® takes the following action to minimise its environmental impact:

  • 100% made in Britain.

  • Component parts all sourced from suppliers located in the South-East of England, &, where possible, within a 10-mile radius of the manufacturing hub.

  • Component parts all dimensionally coordinated; making the manufacturing process an assembly of parts, with no requirement for mains powered machinery, i.e., hand tools only.

  • Component parts all mechanically fixed, with no requirement for adhesives.

  • Orders delivered to site through vehicle-sharing networks, e.g., Zip Car.

Akustak®: Future Sustainability Goals

Akustak® is committed to continuously improving its sustainability practices. Plans include:

  • Laboratory testing of more sustainable module configurations & component parts, e.g., sheep's wool insulation.

  • Obtaining an Environmental Product Declaration (EPD), through the Building Research Establishment (BRE).

  • Achieving Cradle to Cradle certification, through the Products Innovation Institute.
