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...

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 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...

PERFORMANCE REQUIREMENTS 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. One of the biggest impacts in the Approved Document is that of...

ROBUST DETAILS There are 5 Floating Floor Treatments (FFTs) that can be used depending on the base. FFT 1 - Resilient composite deep batten system APG Solution: Profloor Deep Dynamic Batten, Profloor Resilient Batten, Profloor Activ Batten FFT 2 - Resilient cradle and batten system APG Solution: Profloor Levelling System FFT 3 - Resilient composite standard batten system APG Solution: Profloor Dynamic Batten, Profloor Activ Batten, Profloor Resilient Batten FFT 4 - Resilient overlay platform floor system Equal to or greater than 16kg/m2 FFT 5 - Resilient overlay shallow platform floor...

PROFLOOR DYNAMIC BATTEN (55mm - 81mm) Having been used for nearly 20 years on a wide range of timber and concrete floors, the Profloor Dynamic Batten provides excellent levels of impact and airborne sound insulation. The unique dual foam not only provides the performance characteristics but enables minor irregularities in the surface of the sub-floor to be taken up. Standard Sizes 55mm x 3600mm x 45mm wide 67mm x 3600mm x 45mm wide 81mm x 3600mm x 45mm wide Support Batten 50mm x 3600mm x 45mm wide 62mm x 3600mm x 45mm wide 76mm x 3600mm x 45mm wide Flanking Strip 100mm wide x 5mm thick (10m...

PROFLOOR DYNAMIC STRIP (28mm) 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...

PROFLOOR REFURB DECK (26mm) Profloor Refurb Deck System provides the high degree of isolation necessary to give significant improvements in impact sound insulation. Profloor Refurb Deck System utilises the dynamic properties of dual foam technology and a patented edge support strip which prevents fracture of the tongue and grooved joint. Standard - for normal domestic loadings (up to 1.5kN/m2) Hi-load - for floors with higher loadings (up to 4.0kN/m2) Standard Sizes 2400mm x 600mm x 26mm thick Flanking / Support Strip 150mm wide x 7mm thick (10m rolls) An acoustic insulation deck for both...

PROFLOOR ACTIV DECK (31mm) Profloor Activ Deck is a shallow profile overlay board, comprising a resilient layer bonded to flooring grade tongue and groove chipboard. Utilising a uniquely constructed & thermally bonded non-woven material with innovative vertically oriented fibres (VOF), this resilient layer provides enhanced acoustic performance over typical non-wovens. This combined with a minimal impact on floor to ceiling height makes Profloor Activ Deck ideally suited to refurbishment or conversion projects. Standard Sizes 2400mm x 600mm x 31mm thick Flanking/Support Strip 125mm wide x...

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 base Levelling 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...

RECENT PROJECTS ST PAUL’S WAY, LONDON A. Proctor Group recently supplied Profloor Levelling System to Countryside Properties’ recent development of 300 flats at St Paul’s Way, London, E3. Profloor Levelling System was developed in order that a level, finished floor could be laid on a cambered, stepped or uneven sub-floor. The Levelling System is used on typical structural concrete floors where differences in level are too great for a finished floor. The floor is levelled by inserting packers in each Levelling Base to adjust the level of the timber battens and thus create a level finished...
