Park Bearer
- Effective impact and airborne sound reduction for separating floors
- Creates a void for services under the floor
- Proven FFT accreditation for Robust Details and Scottish Example Constructions
- Eliminates the delays caused by screeds
- Use sustainable homegrown UK timber
- Suitable for both new build and refurbishment
Specification
Park bearers consist of softwood timber battens 2400mm long by 45mm wide* with a specially developed 9mm thick resilient foam strip adhered to the underside.
Standard Heights** ( unloaded ) : 54mm , 79mm ( Nom.)
For FFT1 requirements use a 79mm Park Bearer Acoustic Battens.
For FFT3 requirements use a 54mm Park Bearer Acoustic Battens or higher.
Notes :
* Park Bearers comply with the WPIF Code of Practice for Particle Board and OSB Floating Floors (3/2018) which specifies a minimum finished batten width of 45mm. ** It is anticipated that the resilient layer will compress by around 2mm under a UDL of 25kg/m2.

Benefits of Acoustic Bearers
- Effective impact and airborne sound reduction for separating floors
- Creates a void for services under the floor
- Proven FFT accreditation for Robust Details and Scottish Example Constructions
- Eliminates the delays caused by screeds
- Use sustainable homegrown UK timber
- Suitable for both new build and refurbishment
Environment
Acoustic bearers incorporate sustainable timber. Wherever possible the timber used is homegrown to minimise transportation. The Global Warming Potential (GWP) of the resilient layers on the Park and Reflex Bearers is zero.

Bearer Centres
Bearer centres must not exceed 400mm for 18mm chipboard or 600mm for 22mm chipboard based on a maximum UDL of 1.5kN/m2 and concentrated load of 2 kN. Bearer centres should be reduced to 300mm where heavy loads are anticipated. e.g kitchens and bathrooms.
Where anticipated loads exceed these figures please contact CMS Danskin Acoustics.
Park Bearer
Are designed for use on level concrete and steel/concrete composite separating floors as part of a suitable floor and ceiling construction.
Timber floating floors incorporating Park Bearers can provide effective sound insulation on concrete subfloors and eliminate the delays caused by the drying out of screeds.
The cavity created by acoustic bearers can accommodate service runs and underfloor heating systems under the floor.
Park Bearers consist of softwood timber battens 2400mm long by 45mm wide with a specially developed 9mm thick resilient foam strip adhered to the underside.

Our Commitment
The aim of CMS Danskin Acoustics is to correctly interpret the requirements of our customer and, where available, to offer appropriate evidence that our floating floors are suitable for use within their separating floor design. Where our customer requires specific acoustic design advice we will be pleased to assist in directing them to a suitably qualified acoustic consultant.
Floating floor treatments are only one part of a separating floor structure and the correct design, installation and workmanship of the total construction is essential to ensure satisfactory performance. Any evidence provided about the compatibility of a CMS Danskin Acoustics acoustic flooring product is dependent on the customer providing complete and accurate construction information.
The type of evidence which is necessary to justify the inclusion of our products is dependent on the approach taken by the customer to satisfy the regulations.
For each approach the evidence we can generally offer is as follows:
- Building Regulations Approved Document E Guidance Construction / Scottish Example Construction route – where available , laboratory test evidence that a CMS Danskin Acoustics product meets the minimum performance requirements for the relevant floor type as set out in the each document.
- Building Regulations Approved Document E / Section 5 / Part G Pre Completion Testing Route – where available, site test evidence of a similar construction demonstrating performance above the minimum standards. It is the customer’s responsibility to establish whether this evidence is sufficient.
- Robust Detail Construction route – Where available, laboratory test evidence to demonstrate that the product or system meets the rd∆ Lw / rd∆ Rw / rd∆ Rw + Ctr specified in the relevant RD Document.
Installation
To ensure correct installation of floors the manufacturer`s detailed fixing instructions must be followed carefully. Copies of these instructions are available from CMS Danskin Acoustics.
