Before you decide on the noise mitigation barrier for your next project, make sure it achieves these 7 criteria:

Tunable – can it provide different acoustic performance to different sections of the roof?

3-Way Noise-Mitigating – does it have absorb-reflect-absorb performance?

Lightweight – is the wall and frame system as light as possible, i.e. 10-20kg per square metre?

Variable – is it available in a variety of sizes to provide the right amount of surface mass in each noise location?

Scalable – can it be cost-effectively expanded in the future, if necessary?

Easily Attached – can it be easily mounted to a concrete/steel roof or roof platform?

Warranted – is it covered by a 25-year Warranty?
