Introduction to The A. Proctor Group The A Proctor Group has more than twenty years experience in providing acoustic flooring solutions to the industry. This, in addition to research conducted in our own acoustic laboratory, has enabled our acoustic flooring range to keep pace with ever more exacting standards through continued innovation and development. The increasing expectations of householders along with the Government’s targets for higher population densities has placed further emphasis on good acoustic design. The A. Proctor Group is committed to assisting the industry in meeting these challenges.
Profloor Activ Deck 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.
System Benefits • Improved impact and airborne sound performance • High compressive resistance • Excellent resilience • Ease and speed of installation • User friendly • Provided with full APG technical back-up

Skirting Board Potential Expansion Gap 10mm Flanking/Support Strip returned 50mm under Activ Deck
Profloor Activ Deck panels must be supported at all perimeters. The support at room perimeters must be fitted on site using Profloor Flanking/Support Strip. This strip combines perimeter support and isolation of the flooring system from the adjacent structure. Remove a 50mm wide strip of fibre from the edges of the Profloor Activ Deck panels which abut the room perimeter. Profloor Flanking/Support Strip should be attached to the floor around the perimeter to support the exposed area of the panel. (See figure 1.) When laying in a refurbishment situation with door facings in position, the application is simplified by cutting 40mm off the bottom of the facings. This allows the Profloor Flanking/ Support Strip and board to slip underneath. Profloor Flanking/Support Strip is supplied, normally 150mm wide, and can be supplied with or without 50mm double sided tape.
Figure 1
Commence laying Profloor Activ Deck panels in the corner furthest from the point of access. Apply the Profloor Flanking/ Support Strip and ensure it is positioned between the perimeter structure and the Profloor Activ Deck panel. Lay the Profloor Activ Deck panels, along the full length of the room, ensuring the exposed edge is properly aligned to allow a straight joint for the next line of panels. Profloor Activ Deck panels, in adjacent rows, should be staggered by a minimum of 400mm. The offcut from the previous row should be used at the start of the next row, provided that it is not less than 400mm. (See figure 2.) Figure 2
Allow for the possible expansion of the Profloor Activ Deck panel by leaving a gap between the free edge of the panel and the perimeter wall or other abutment. This gap should be calculated as 1mm per linear metre of flooring and in no circumstances should be less than 10mm. (See figure1.) Mechanical fixings must not be used to fix main flooring panels. Apply Profloor Adhesive to the T&G joints of all Profloor Activ Deck panels before butting them together. (See figure 3.) Remove any surplus adhesive, before it dries, from the surface, with a damp cloth.

It is imperative that all services are in place prior to laying the Profloor Activ Deck panels. Services cannot be accommodated between Profloor Activ Deck and the sub-floor. Where access is required to services below the subfloor, the Profloor Activ Deck panel can be cut to suit. Where Profloor Activ Deck panels are butted together, without the tongue and groove, ie. in doorways, a Profloor Support Strip must be attached to the end of each board. This is the only situation where mechanical fixings may be used. (See figure 4.) At the perimeter, fold the Profloor Flanking/Support Strip over, onto the Profloor Activ Deck, apply weight to compress the system (the Tradesman’s weight is normally sufficient) and fix the skirting so that it rests on the Profloor Flanking Strip. Trim the edge of the Profloor Flanking Strip flush with the skirting.

To prevent damage by following trades, the finished floor should be covered with a protective layer immediately after installation.
