An acoustic batten is a traditional soundproofing solution for timber and concrete floors. When correctly installed they assist in helping a development meet Part E Building Regulations. The battens consist of a sustainably sourced timber upper layer with a high performance resilient layer on the bottom. Soundproofing battens are traditionally available in two heights; 45mm and 70mm. Supplied in lengths, the battens can span up to 2.5 metres.
Acoustic Battens on Concrete Floors
Soundproofing battens are an effective soundproofing solution for concrete floors. Both 45mm and 70mm variants are suitable for this build type. To complete the system an acoustic flanking strip is installed around the floor perimeter and a timber sub deck laid on top of the acoustic battens. This creates a void in-between the battens that can be used to to run cables and services. Floor finishes are then installed on top of the timber sub-deck.
Acoustic Battens on Timber Floors
Soundproofing materials must compensate for the lack of mass in timber floor developments. In this scenario 70mm battens must be installed. Additional layers must also be installed to complete the system:
- An acoustic plasterboard and OSB chipboard above the battens
- Mineral wool in-between the acoustic battens and the timber joists
- Resilient bars and acoustic plasterboards beneath the timber joists
- Acoustic flanking strip around the floor perimeter
Acoustic Batten Alternatives
Dry screed acoustic floor boards have become a hugely popular alternative to soundproofing battens for soundproofing timber and concrete floors. The boards concrete finish provides sufficient mass without the need for multiple soundproofing layers. This means that dry screed boards have significantly less impact on floor height compared to a soundproofing batten system. A dry screed board is ready to accept floor finishes at 28mm thickness, whereas a timber batten system will be at 107mm. The boards also provide a more solid underfoot experience compared to batten systems.
