SITE CONDITIONS SITE CONDITIONS It is essential that site conditions are suitable for the installation of the Profloor Dynamic Batten system and laying should not commence until the correct conditions are achieved.
SUB-FLOOR The sub-floor must be hard, dry and swept clean. The surface should be such that the Profloor Dynamic Battens can be laid flat.
SUB-FLOOR LEVELS Timber frame sub decks, timber floors, screeded floors and in-situ concrete floors finished with a fine tamped surface, are suitable for the installation of the Profloor Dynamic Batten System provided that they are generally level. Precast pre-stressed concrete floors are designed with a camber. On spans up to 5 metres, the use of the Profloor Dynamic Batten System has proved satisfactory but this is dependent on the installation of the pre-cast concrete slab. The unique two layer fully bonded foam system allows the soft foam element to take up some unevenness and contours of the sub-floor. For uneven floors Profloor Levelling System may be considered.
COMMENCEMENT OF LAYING The floor system should be programmed to be laid as late as possible. All windows should be installed and glazed, wet trades completed and sufficient time allowed for thorough drying out.
CARE OF MATERIALS Profloor Dynamic Battens should not be delivered to site until dry storage is available, preferably in the area where it is to be laid. As a general recommendation, we would advise that a moisture resistant type of flooring is used in conjunction with Profloor Dynamic Batten system.

Laying on Timber • Platform floor with absorbent material • Ribbed joisted floor with absorbent material • Ribbed joisted floor with heavy pugging • Ribbed joisted floor with Independent ceiling • Robust Detail E-FT1, E-FT-2
1 LAYING PROCEDURE The Profloor Dynamic Batten System should be laid in accordance with BS 8201:1987. Copies of the laying procedures are available to every site. Relevant trades must follow these carefully to ensure a satisfactory installation. (See figure 1 and 1b) for general layout.
2 PERIMETER BATTENS Concrete sub-floor: Single row of Profloor Support Battens around floor perimeter; maintain 50mm gap between wall and batten. Timber sub-floor: Single row of Profloor Dynamic Battens around floor perimeter; maintain 50mm gap between wall and batten. (See figure 2.)
3 SPACING OF BATTENS Batten spacing to be in accordance with flooring manufacturer's recommendations - Commonly: 400mm centres (450mm max) for 18mm chipboard and 600mm centres (max) for 22mm chipboard. (See figure 3.)
4 BATTEN STAGGER Batten joints in adjacent rows should be staggered by a minimum of 600mm.
05
INSTALLATION DETAILS 5 PACKING STRIPS Packing strips may be placed under the batten to stabilise the floor where necessary. On pre-cast concrete sub-floors, with spans in excess of 5 metres, a common method to minimise the effect of any camber, is to divide the floor area by mounting the partitions off the sub-floor, on an individual room basis. (See figure 4.) Consult the manufacturer where individual floor areas exceed 150m2 or the camber is greater than 20mm. Consider Profloor Levelling System. Advice from The A. Proctor Group Tech Desk is available.
6 MOUNTING PARTITIONS Where non-loadbearing partitions are to be mounted on the finished floor, install a double row of Profloor Dynamic Battens along the line of the partition. (See figure 5.) Particular care must be taken in the batten layout. Alternatively, use short lengths of Profloor Dynamic Battens as noggins between adjacent battens, at centres to suit flooring board thickness, to create a 'ladder' under the partition line. (See figure 5c.)
7 FIXING FLOORING The specified flooring boards should be placed lengthways across the battens ensuring board ends are supported by a batten. Ensure the ends of the boards in adjacent rows are a minimum of 400mm apart. Concrete sub-floor: Apply a line of Profloor Adhesive to the top of Profloor Dynamic Battens prior to installing the flooring boards. Apply Profloor Adhesive to the tongued joints of all flooring boards before
06
INSTALLATION DETAILS butting them together (See figure 7.) and fix in the normal manner*, preferably using screws (or annular ringed shank nails). (See figure 6.) It is important that the fixings do not penetrate the batten and foam to the sub-floor. Remove any surplus adhesive from the surface, before it dries, with a damp cloth. Adequate gluing will help reduce potential squeaks. Timber sub-floor: Apply a line of Profloor Adhesive to the top of Profloor Dynamic Battens prior to installing plasterboard plank (or similar gypsum based board). Spot bond the flooring boards using Profloor Adhesive to the plasterboard plank. Offset all joints of the flooring boards from the joints of the plasterboard plank. Apply Profloor Adhesive to the tongue and groove joints of all flooring boards before fitting them together. (See figure 7.) No further fixings are necessary, but if required, preferably screws (or annular ringed shank nails) may be used in the normal manner*. It is important that the fixings do not penetrate the batten and foam to the sub-floor. Remove any surplus adhesive from the surface, before it dries, with a damp cloth. Adequate gluing will help reduce potential squeaks. *Seek the advice of the flooring board manufacturer for details of fixings.
8 EXPANSION OF FLOORING MATERIALS Allow for possible expansion of the flooring material by allowing a gap between the free edge of the floor board 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 figure 2 and 2b.)
9 GAP AT WALL OR DOOR FRAME Ensure that the floor boarding does not make contact with any part of the wall structure including door frames and the like. Use Profloor Flanking Strip at all perimeters and abutments to ensure this separation. (See figure 2 and 2b.)
07
INSTALLATION DETAILS 10 SERVICES WITHIN FLOORING SYSTEM Service runs should be parallel or perpendicular to batten direction and in banks of 200mm* maximum, with a minimum of 400mm separation between adjacent banks. Ensure a minimum of 150mm between services and any perimeter wall.** Do not notch battens, instead, cut battens through and install either side of service run ensuring the batten ends do not come into contact with the services. Isolate all services coming through the floor using Profloor Flanking Strip. (See figure 8.). Where access is required to services below the flooring system, the necessary hatch can be cut in the floor finish material. Additional battens should be placed around the perimeter of the hatch to support the main floor and the hatch cover. The floor finish is fixed to the battens in the normal manner. Ensure correct specification of batten depth to accommodate services allowing 12mm for compression of the foam. *in cases of Robust Detail constructions, the gap between batten ends where battens have been cut to accommodate perpendicular service runs, should be no more than 50mm. **other than radiator legs.
11 SUPPORTING NOGGINS Where ends of flooring boards fall between a line of battens, place a continuous length of batten for support with each board securely fixed to it following advice given in 7 Fixing Flooring.
12 DOORWAYS Continue the perimeter Support Batten (or Profloor Dynamic Battens on Timber sub-floors) past the door opening. Where butt joints are formed at thresholds, place a continuous length of Support Batten *1directly beneath the joint of adjacent boards with each board securely fixed to it. The joint must be glued and where deemed necessary for a secure fix, screws should be used to secure both edges of the butt joint to the same batten. Allow a gap between the batten, flooring and doorframe for the Profloor Flanking Strip. Care should be taken at the design stage to ensure that fire stops are fitted to the same standard as that required for the fire doors. Technical advice can be provided for individual projects. (See figure 10.) *1Use profloor Dynamic Batten on Timber Sub-floors.
08
INSTALLATION DETAILS 13 SKIRTING BOARDS Fold the Profloor Flanking Strip onto the flooring board, apply weight to compress the system (tradesman's weight is normally sufficient) and fix the skirting so that it rests on the flanking strip. Trim the edge of the Profloor Flanking Strip flush with the skirting (see figure 2.)
14 KITCHEN / BATHROOM (areas of increased loadings) When a concentrated floor loading is in excess of 1.5kN/m2, (i.e. kitchens, bathrooms, cupboards containing water heaters etc‌ it is necessary to modify the batten installation to provide additional support. It is also recommended that hallways, both internal and common, be treated in the same manner to accommodate the combination of high foot traffic and small floor areas. Concrete sub-floor: Profloor Support Battens should be used in lieu of Profloor Dynamic Battens, using the same method for installation. The support batten will give the same finished floor level, under the loaded floor, as the standard system under normal loading. Timber sub-floor: Profloor Dynamic Battens should be installed with spacing closed to 300mm centres. Alternatively, Profloor Support Battens may be used at the normal centres. Where night storage heaters are to be supported off the floating floor, additional battens should be installed to sufficiently support the increased load. Contact The A. Proctor Group Techdesk for further advice.
15 PROTECTION To prevent damage by following trades, the finished floor should be covered with a protective layer immediately after installation.
