Reflex Bearer

Acoustic Batten for Soundproofing Timber Floors

An extensive process of research and development over many years enabled CMS Danskin Acoustics to produce an innovative flooring bearer with an exceptional level of acoustic performance. Reflex Bearer Acoustic Battens comprise softwood timber with a unique double density resilient fibre layer which provides a high degree of impact sound reduction.

Reflex Bearer Acoustic Battens contribute significantly to the reduction of impact and airborne sound on level timber or lightweight steel constructions and on concrete subfloors in new build and refurbishment applications. The softwood timber has either FSC accreditation as standard or PEFC on request.

Specification

Reflex Bearer Acoustic Battens

Reflex Bearer Acoustic Battens comprise softwood battens 45mm ( Nom.) wide by 2400mm long with a specially developed resilient fibre strip 17mm thick adhered to the underside. They can be preservative treated if required. On average it is expected that the resilient layer will compress by around 4mm under normal loading.

Standard Heights ( unloaded ) : 53mm , 75mm and 87mm ( Nom.)

Other sizes are available to order. Timber is FSC certified as standard.

For FFT1 requirements use a 75mm Reflex Bearer Acoustic Battens.
For FFT3 requirements use a 53mm Reflex Bearer Acoustic Battens or higher.

Performance

Laboratory values for Reflex Bearer Acoustic Battens are shown below.

Accessories

High Load Bearers
It is an essential feature of effective floating floors that they deflect vertically in order to absorb impact energy and therefore reduce sound transmission. However effective deflection under areas of high load such as kitchen and bathroom furniture is not desirable. While this can sometimes be lessened by reducing batten centres or using double rows of Reflex Bearer Acoustic Battens, limited numbers of high density foam battens can sometimes be used in these local areas. On concrete subfloors High Load Bearers are also recommended for use at room perimeters. As High Load Bearers have a lesser acoustic performance than Reflex Bearer Acoustic Battens a warning message regarding excessive use is printed on the top surface. High Load Bearers are manufactured to a similar height as compressed Reflex Bearer Acoustic Battens ( ie, Reflex height less 4mm ) and provide superior support.

Danskin Flanking Strip
This is placed at the perimeter of each floor . The 6mm thick preformed “L” shaped acoustic foam is supplied in strips 1.8m long and packed in bags of 100 lineal metres.The innovative “L” shape makes the flanking strip easy to fit and one size fits all floors. It is lightly trapped between the bottom of the skirting and the top of the flooring board with the excess neatly trimmed off.

Danskin Acoustic Quilt ( as required )
Where required to achieve a particular acoustic performance CMS Danskin can supply acoustic quilt.
