SIMPLE EFFECTIVE SOLUTIONS

DevelopmentThe 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 www.proctorgroup.com or directly from the dedicated technical advisors on our Tech line – 01250 872261• 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

FUNDAMENTALS OF SOUND TRANSMISSION

Sound Passage Through AirSound 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

Airborne SoundNoise 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 soundThe 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.

Main sources of structural borne sound are people (footsteps, slamming doors etc), plant machinery, services and household appliances.

The ProblemThe 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 SolutionExperience 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.

England and Wales - Approved Document E

The current version of Approved Document E – Resistance to the Passage of Sound came into effect 1st July 2003. 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.

Airborne sound - DnT,w Minimum 52dB

Scotland - Section 5. Northern Ireland - Part G (New Build). Ireland - Document E

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.

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.

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.

PRE-COMPLETION TESTING

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.

PROFLOOR DYNAMIC STRIP

Profloor Dynamic Strip System, designed for new build and the refurbishment of existing timber floors, is stapled, using the fixing lugs provided, to the timber joists.

Significant improvement in Impact Sound Insulation can be obtained when using Profloor Dynamic Strip System under the chosen floor finish.

The Profloor Dynamic Strip System utilises the same advanced foam technology as the Profloor Dynamic Battens, to provide an impact isolation superior to that achieved using fibre quilt. Profloor Dynamic Strip has been developed in conjunction with Building Scientists at Heriot - Watt University.

The use of Profloor Support Strip is recommended around the perimeter of all rooms and in areas such as bathrooms and kitchens where the load could exceed 1.5kN/m2.

The 3rd element of the Dynamic Strip System is the use of a 5mm Profloor Flanking Strip to isolate the acoustic floor from the wall and skirting board.

PROFLOOR LEVELLING SYSTEM

The Profloor Levelling System was developed in order that a level finished floor could be laid on a cambered, stepped, or uneven sub-floor. Robust Detail constructions can still benefit from a levelling system that provides the final level and takes out any irregularities particularly in a mortar screed surface.

Types of baseLevelling bases are manufactured from injection moulded high grade polymer, 70mm x 100mm in three types:

Type L+M with 10mm foam bonded to the base.

Type H is for deeper floors with the foam bonded to timber blocks, which fit under the Levelling bases. Profloor Packers in 2mm, 3mm and 5mm thickness are inserted in the cradles to adjust the final level of the floor.
