The benefits of high-performance acoustic insulation

A more comfortable sound environment

Minimising the noise that comes from pipes and machinery within an industrial space is simply good design. Acoustic insulation absorbs and blocks sound waves, reducing the transfer of noise transfer, and helping to create a quieter, more comfortable environment.

Insulating for sound makes people more productive

Within a commercial building, noise can adversely affect productivity and overall wellbeing. Whether it’s in school, hospital, or in a workplace environment, acoustic insulation helps dampen noise and minimise noise transfer.

Pipe insulation for sound control

Pipe-lagging around ductwork, wastewater, waste supply, and stormwater pipes can also isolate noise emitted from pipes. Effective acoustic lagging uses a heavy barrier (such as loaded vinyl) isolated from the pipe with foam rubber or fibreglass. It should also extend along the full length of a pipe, leaving no gaps.

Acoustic insulation to control noise from services

Sound barriers help control noise from cooling fans, transformers and other noise producing electrical equipment in electrical plantrooms. Insulation is also effective in isolating sound in lift shafts and other services areas within a building.

Acoustic insulation that’s guaranteed compliant

At Baron Insulation, we’ll help you choose the most effective acoustic insulation materials to do the job and satisfy all National Construction Code (NCC) standards for building and plumbing applications.

How do you measure noise?

The sound absorption performance of a material is measured by its noise reduction coefficient (NRC). The NRC rating is affected by the type of absorbent material, its thickness and density, and its mounting method. The NRC figure ranges from 0.00—perfectly reflective—to 1.00—perfectly absorptive. To measure noise and work out what you need for your project, use our noise calculator.

Which material works best for effective acoustic insulation?

Commercial and industrial building designers specify different materials, such as glasswool, rockwool, polyester fibre, natural wool, or cellulose fibre, to absorb sound. Here at Baron Insulation, you’ll find a whole range of effective sound absorption and soundproofing solutions to suit your commercial building or plumbing project.
