2 INNOVATION BUILT ON EXPERIENCE SIMPLE EFFECTIVE SOLUTIONS Development The A. Proctor Group Ltd has been providing technically advanced acoustic products to the construction industry since the 1980 s. In that time the focus has been on innovative high performance acoustic flooring systems capable of exceeding the Building Regulations for sound. The company has established strong relationships with customers and suppliers delivering solutions required by todays demanding construction industry. Links with universities have been one of the bedrocks of our research and development and this continues, resulting in the production of more efficient and durable systems. Why use Profloor? In addition to an extensive portfolio of dynamic acoustic products The A. Proctor Group offers: Full technical support from specification through to site from our Specification and Distribution Managers throughout the UK Specialist technical advice either on-line at or directly from the dedicated technical advisors on our Tech line All products readily available through a national network of distribution partners The benefits of Profloor Significantly reduces impact and airborne noise pollution in multi level buildings. Ideal for both new build, refurbishment and conversions Supremely versatile, making it suitable for most domestic flooring applications. Easy and fast to install to timber joisted or concrete floors (pre-cast or in situ) with no wet trades involved. Floors can be used immediately after installation. Warmer floor surface. Designed to last the lifetime of the floor. Non load bearing partition walls can be erected on the finished acoustic floor where a double batten run has been positioned beneath the wall. Services can be run in the void created by Battens and access gained by siting a hatch Shallow profile systems as little as 4mm to minimise floor build-up 02

3 FUNDAMENTALS OF SOUND TRANSMISSION Sound Passage Through Air Sound is created by a source of vibration. This movement is then transmitted through the air in the form of waves of pressure. This pressure is made up by the movement of air particles against one another and is picked up by us as vibrations within the ear. The Basis of Sound Transmission Source Path Receiver Airborne Sound Noise transmission through buildings travels in two main ways. The first is airborne sound, which can be transferred from the sound source along a continuous path to a listener. Examples of how sound can be transmitted through the structure could be through small holes or openings in the construction, along ductwork or forced transmission through partitions or floors. Airborne sound is affected by Gaps in joints Cracks in masonry or plasterwork Insufficient sealant around pipes etc passing through the structure Mass of the construction Effective isolation and absorption layers Impact sound The second means of sound transmission is impact or structure borne sound. This is where mechanical or kinetic energy is being imparted directly to a building structure as the result of steady vibrations or impacts. These are then transmitted throughout the construction to other rooms in the building where a partition, structure or surface is forced into vibration, thereby creating sound. Without Isolation With Isolation Main sources of structural borne sound are people (footsteps, slamming doors etc), plant machinery, services and household appliances. The Problem The most effective method of reducing structure borne sound in floors is to provide a resilient interlayer between the finished floor and the structural base. However, many test failures are due to disintegration of the glass/mineral fibre quilt or inadequate resilience provided by the acoustic floating floor. The Solution Experience has shown that highly resilient materials such as open-cell foam or vertical fibres, whether used in strip form or distributed layer, will provide excellent long term isolation of impact sound and deliver the best in deflection and durability. Adequate deflection can be provided initially by some materials, but over a period of time the effectiveness can often be severely impaired owing to poor resilience or creep under continued dynamic loading (footsteps). It is therefore essential that the interlayer material provides both adequate deflection and long term durability. The best materials available to date which can provide these combined properties are open-cell polymer foam and vertical polyester fibres the key to the success of Proctor Group s range of Profloor products.

4 PERFORMANCE REQUIREMENTS The current version of Approved Document E Resistance to the Passage of Sound came into effect 1st July With it came widespread changes which are having a substantial effect on the way buildings are designed. As well as greater levels of sound insulation between dwellings and rooms for residential purposes, the regulations now include performance standards for reverberation within common areas, floors and some walls within a single dwelling and school acoustics - areas not previously encompassed. One of the biggest impacts in the Approved Document is that of Pre-Completion Testing, to be carried out on 10% of dwelling types in each development to prove compliance with the requirements set down in the document. England and Wales - Approved Document E Element Airborne sound - site test DnT,w + Ctr Impact sound - site test L,nT,w Separating floors between dwellings and rooms for residential purpose Separating floors between rooms created by a change of use Minimum 45dB Minimum 43dB Maximum 62dB Maximum 64dB Scotland - Section 5. Northern Ireland - Part G (New Build). Ireland - Document E Floors Airborne sound - DnT,w Impact sound - LnT,w Minimum 52dB Maximum 61dB PRE-COMPLETION TESTING Testing of dwellings once completed, is common practice in Scotland. Sound testing began over 20 years ago in the mid eighties when over 40% of walls and 60% of floors were failing. Recent surveys have suggested that the failure rate in Scotland for new-build is now below 5% and shows the learning curve that has had to be addressed and the benefits that testing can provide. However, the Pre-Completion Testing regime did meet with some resistance when proposed in the new Approved Document E. The implications and costs to the construction industry in England and Wales were set to be high, with stoppages of work during testing, the costs of the tests themselves and potential remedial action should there be failures. Along with Pre-Completion Testing, there are new standards for impact and airborne sound with a new method of assessing airborne sound, to put heavier weighting on the lower frequencies to try and address the areas of complaints. This emphasis at low frequencies would affect lightweight or coupled structures most and therefore designers had to look at de-coupling the structure or adding mass. LONG-TERM SOLUTION It must be noted that the RD process and the FFT classifications, whilst proving the acoustic performance of a product, do not assess the product s long-term durability in a domestic application and third party accreditation such as BBA certificates should be sought to prove the product s suitability for use long-term
