Sound investments

The nature of metal deck profiled roofs has long presented a challenge when it comes to controlling reverberation and creating environments which are fit for purpose. However, it presents an opportunity for the specialist contractor to add value to a project, by offering practical acoustic roofing solutions.

To reduce sound transmission in a metal roof, the general principle is to add mass and introduce insulation. Acoustic consultants will often include several variable layers within an acoustic specification, which has the potential to result in a high build-up.

Where the underside of the metal roof decks is perforated, AIM Acoustic Trough Infills are typically installed within the profile to provide direct acoustic insulation. The application of the trough infills essentially reduces reverberation of sound within the roof zone and improves sound quality. One such example of this was the O2 Arena in London where AIM precision manufactured the profiles to an exact design and to bespoke dimensions.

Where the metal deck is not perforated, AIM Acoustic Trough Infills still offer a robust solution when used in combination with Euroform’s Versapanel®. To help keep the roof profile to a minimum, Versapanel® aids acoustic performance by adding a mass layer. As Versapanel® is available in a range of thicknesses which provide sound reduction from 30dB to 38dB, the lowest thickness can be specified to achieve the required performance. Due to its tolerance of any weather conditions, using Versapanel® means work can carry on uninterrupted.

While you can use Versapanel® independently with a roof build-up to reduce sound transference, as was the case at Dublin’s Terminal 2 Airport, in higher performance applications creating an AIM/Euroform system offers several benefits.

For example, AIM Acoustic Trough Infills are constructed of high density stone wool which delivers excellent sound insulation. When combined with Versapanel®, they enable effective sound control while keeping the overall build-up to a minimum.

That’s a practical insight on the types of products you can use in combination to create a robust acoustic roofing solution. For contractors looking to add value, acoustic know-how is a skill worth adding to your list.
