Floating Floor System Technical Specification

for R10 When used on a timber suspended floor


If used with our Studio Ceiling System on the ceiling below, the Floating Floor System should pass the Part E Building regulations for house conversion and new builds. The data below is based on a customer installing both systems.

05 SBM5 R2 Floating Floor System Tech Data

Incorporating the latest changes to the Approved Document E, the minimum and maximum airborne noise and impact sound insulation requirement for separating floors are as follows:

Properties Values

  Airborne Sound Reduction DnTw,w+C;tr Impact Sound Level LnTw
Conversion 43dB or greater 64dB or less
New Build 45dB or greater 62dB or less

To comply with the requirements of Document E, R10 sound insulated separating floors have been tested in accordance with BSEN ISO 717-1997 and BSEN ISO 717:1997. Substituting the 25mm mineral wool floating layer normally specified with a more stable and efficient recycled rubber resilient layer. 10mm thick sound absorbing Acousticel R10 is installed onto timber suspended floors as detailed above. Note: Existing or new square edged timber floors should be overlaid with our SBM5 before installing the R10 and the ceiling should be supported with our 16mm deep Resilient Bars.

With a floating layer of 19mm thick QUIETBOARD cement impregnated t&g chipboard -placed on top of the R10 acoustic insulation as shown above, the following site test result was recorded:

. Site test result

Airborne DnT,w+Ctr 48dB  
Impact LnTw 52dB  
With R10 and QuietBoard installed on top of a base floor of QuietBoard, the following site test result was recorded:
Airborne DnT,w+Ctr 55dB
Impact LnTw 55dB

WHICH MEETS THE NEW CHANGE OF USE, CONVERSION AND NEW BUILD REQUIREMENTS NOTE! Size and spacing of the timber joists will affect the overall sound insulating performance. If the joists differ from those on the floor that was tested, please contact us for further advice.

NOTE: Failure to follow the Application Instructions to the letter may result in a failed test!

Quietboard Flooring

. General Physical Data

Description: Tongued & Grooved Acoustic Floor Panel
Composition: Cement Impregnated Chipboard (75 % of this product is made from recycled wood pulp)
Standard Size: 1200 x 600mm or 4ft x 2ft (cover size)
Nominal Thicknesses: 18mm (tongued and grooved)
Mass: Min. 1359kg/m3 (25kg/m2)
Flammability: Class ‘0’ non-flammable



QuietBoard is usually delivered secured in plastic wrapped and edge protected pallets. When loose boards are transported they must be laid flat and fully protected with a waterproof sheet. When manually moving, QuietBoard must be carried in a vertical position. Storage QuietBoard should be stored flat on levelled supports at 800mm centres. It must never be stored on edge or upright. If outside, a protective plastic sheet must be secured to protect from weather


QuietBoard should be stored flat on levelled supports at 800mm centres. It must never be stored on edge or upright. If outside, a protective plastic sheet must be secured to protect from weather


QuietBoard has an ex-works moisture content of 9% =/- 3% and is in equilibrium when the temperature is 20oC with a relative air humidity of 50-60% QuietBoard adapts to the ambient humidity level, therefore, to adjust to its working conditions it should be allowed to acclimatise for 24-48 hours prior to fixing.

Our Acoustic Sealant is a one-part Fire Retardant Water-based Acrylic Sealant. It exhibits good adhesion to a wide variety of common building substrates without the need for a primer. Paintable with emulsion paint three hours after application. Allow 12 hours before overpainting with gloss paints.

When subject to flame our sealant will intumesce (expand and char), thus blocking the passage of fire and smoke.

Application Instructions

Joint preparation

The joint surfaces must be clean, dry and free from all contamination. The surfaces should be degreased using a suitable cleaner.

Joint Backing

Where applicable, appropriate joint filler e.g. our AMW or closed cell polyethylene foam, should be used to provide the correct joint depth (see chart under Technical Data for fire integrity and insulation achieved).


Our sealant is supplied in cartridges and can be applied into the joint using a Caulking Gun. All joint preparation, priming, and sealant application should be carried out in accordance with BS8000 Part 16, the British Standard for the sealing of joints in buildings using sealants.

Joint Size suitability

Joint width

Minimum 6mm
Maximum 20mm (single application)

Joint Depth

Minimum 10mm on porous substrates
Minimum 10mm on non-porous substrates
Maximum 20mm

Width :Depth ratio (within above min/max restrictions)

Contact Technical Services. In general, joints should be as narrow as possible to prevent passage of fire.

Storage Life

12 months in original unopened package stored in a cool, dry place out of direct sunlight.

Health & Safety for Acoustic sealant

Avoid prolonged contact with the skin. If sealant cones into contact the eyes, flush with copious volumes of cold water and obtain medical attention. For further information consult Product Safety Data Sheet.
