Partnerships in action••••••••••••••••••••• THE HISTORY The A. Proctor Group Ltd, a privately owned company based in Scotland, has been serving the U.K. construction industry with a wide portfolio of technically advanced products for over 3 decades. The company has forged extensive links with universities, colleges and suppliers which have led to the production of more efficient, more durable and lower cost products. One such partnership, with Heriot-Watt University, Edinburgh has led to the development of a full range of unique patented, party floor acoustic systems.
THE DEVELOPMENT Prompted by the Building Research Establishment’s findings, The A. Proctor Group, in 1986, embarked on a major programme of research and development in collaboration with the Heriot-Watt University, backed by the Science and Engineering Research Council which resulted in a series of new and innovative resilient flooring products.
(below) The A. Proctor Group’s Head Office- The Haugh Blairgowrie, Perthshire
This research has recently been expanded to include collaboration in product development at one of Europe’s leading materials research centres, Napier University. The A. Proctor Group has a policy of ongoing collaborative research as a basis for continuous innovation in material science and product design.
THE A. PROCTOR GROUP The Quiet Revolution Insulation of party floors against IMPACT and AIRBORNE sound transmission is a statutory requirement of the Building Regulations. The A. Proctor Group commissioned a comprehensive independent research programme into the problems associated with sound transmission in party floor constructions. This research combined with extensive laboratory and on-site testing, produced the single component solution in the Profloor Dynamic Batten. The concept of the Profloor Dynamic Batten utilises the dynamic properties of open cell polymer foam technology using a unique two layer fully bonded system. This foam combination eliminates the requirement for the mineral fibre quilt which is required with existing closed cell resilient batten systems. Profloor Acoustic Systems are a group of products specifically designed for the reduction of sound transmission. These use the same open cell foam technology to provide solutions for both new build and refurbishment projects. A nationwide technical specification team, together with Techline Advice Centre, ensure professional response to the industry’s requirements. A national network of distribution outlets ensures prompt and effective service.

The importance of Acoustic Insulation••••••• THE PROBLEM Research has shown that traditional closed - cell integral foam battens provide as little as 1dB additional insulation compared with ordinary timber battens. The entrapped air prevents the deflection necessary to provide satisfactory isolation.
Tongue and Groove Profloor Dynamic Batten
Open-cell foam, whether used in strip form or distributed layer, will provide excellent long term isolation of impact sound up to 9dB quieter than that obtained using traditional closed-cell battens.
THE SOLUTION Concrete Planks
The most effective method of reducing structureborne sound in floors is to provide a resilient interlayer between the finished floor and the structural base. Many of the failures recorded in post-war designs were due to disintegration of the glass/mineral fibre quilt or inadequate deflection by the foamed plastic strip which formed part of the integral resilient batten. Deflection and Durability The application of vibration isolation theory indicates that a deflection under imposed loading of 6mm is required, to provide adequate impact sound insulation. This deflection cannot be provided by the traditional closed-cell polymer foam battens because the pneumatic resistance of the entrapped air limits the vertical movement to ‘less than 1mm under normal domestic loading’.
NEW PART E 2003 As of 1st July 2003, a major change to Approved document E of the Building Regulations for England and Wales came into effect. Key changes to this document include: • A change in the measurement criteria; • A change in the sound insulation levels required; • The introduction of pre-completion testing [10% of all new dwellings will have to be tested by an accredited third party]; • Inclusion of schools and rooms for residential purposes. DnTw + Ctr measurement uses a spectrum adaptation to give greater emphasis to lower frequencies. This highlights a structure’s strength or weakness at insulating against typically intrusive low frequency noise. 'Robust Details provide an alternative to precompletion testing for new build houses and apartments. These comprise a set of details of construction for timber, concrete and steel wall and floor systems. The A. Proctor Group has been closely involved with this process from its inception, and several of the Profloor Systems meet the requirements as Floating Floor Treatments for use in Robust Details (see page 7 for details).

THE BENEFITS • For both new build and conversions. • Significantly reduces impact and airborne noise pollution in multi level dwellings. • Versatile, suitable for most domestic flooring applications. • Easy and fast to install to wooden joisted or concrete floors (pre-cast or in situ) with no ‘wet trades’ involved. • Use of floors immediately after installation. • Warmer floor surface. • Will 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 Dynamic Batten and access gained by siting a hatch. Profloor Systems comply with: Building Regulations 2003 - Approved Document E Building (Scotland) Regulations 2005 - Section 5 Building Regulations (Northern Ireland) 1990 - part G Building Regulations (Ireland) 1991 - Document E Regulation Requirements (BS 5821 - 3: 1984, ISO 717 - 3: 1982)

DYNAMIC BATTEN Profloor Dynamic Batten System is specified and detailed similarly to a standard batten, for the purpose of supporting the chosen floor finish, but has the advantage of providing effective isolation of the floor finish from the structure. Significant improvement in Impact Sound Insulation can be obtained when using Profloor Dynamic Batten System in timber and concrete construction. Profloor Dynamic Batten System, a market leader in the manufacture of floating floors for both new build and refurbishment projects, utilises advanced foam technology to provide an impact isolation superior to that achieved using fibre quilt.

RECOMMENDATIONS Mechanical fixings must not penetrate through the timber batten into the foam systems. We recommend that tongued and grooved flooring is bonded using Profloor PVA Woodworking Adhesive. It is intended that under normal domestic load the double foam system will compress by up to 8mm.

The use of Profloor Support Batten is recommended around the perimeter of all rooms and in areas such as bathrooms and kitchens where the load could exceed 1.5kN/m2. Support Batten may not be required when used on timber floors with 19mm plank. If closer centres are required please contact APG Techline. The 3rd element of the Dynamic Batten System is the use of a 5mm Profloor Flanking Strip to isolate the acoustic floor from the wall and skirting board. o

Proprietary Acoustic Systems Manufacturers Association statementThe New Approved Document E 2003 introduces a new unit of measurement for airborne sound which places more emphasis on low frequency performance. Due to the inherent difficulties of measuring low frequency noise a significant tolerance on the accuracy of
airborne sound test results should be expected . In practical tests PASM have witnessed relatively large variations in airborne sound results by different measurement contractors on the same floor. Site conditions and workmanship can also limit reproducible results, therefore previous results should be viewed as indicative performance only.
