The A. Proctor Group has a dedicated Technical Department which
can assist with installation details, view drawings for approval and give
specialist advice on the correct use of the A. Proctor Group products.
For Technical Advice on installation details and product applications
contact the A. Proctor Tecline:
The Profloor Excel 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.
For Timber Floor Installation:
Battens should be laid over a structural subfloor and perpendicular to the floor joists. 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. Batten joints in adjacent rows should be staggered by a minimum of 600mm. General
layout of battens is shown in figure 1.
For Concrete Floor Installation:
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. Batten joints in adjacent rows should be staggered by a minimum of 600mm. General
layout of battens is shown in figure 2.
Single row of Profloor Excel Battens to be laid around floor perimeter; maintain 50 mm gap
between wall and batten. See Figure 3 & 4.

PACKING STRIPS
Packing strips may be placed under the batten to stabilise the floor where necessary.
For Timber Floor Installation:
A common method to minimise the effect of any uneven-ness, is to divide the floor area by
mounting the partitions of the sub-floor, on an individual room basis. (See Section 3 – Mounting
Partitions). Consult the flooring manufacturer where individual floor areas exceed 150m2 or the
variation in levels is greater than 20mm. Advice from the A. Proctor Group Tech Desk is available.
For Concrete Floor Installation:
On pre-cast concrete sub-floors, with spans in excess of 5 meters, a common method to
minimise the effect of any camber is to divide the floor area by mounting the partitions of the
sub-floor, on an individual room basis. (See Section 3 – Mounting Partitions). Consult the flooring
manufacturer where individual floor areas exceed 150m2 or the camber is greater than 20mm.
Advice from the A. Proctor Group Tech Desk is available.

MOUNTING PARTITIONS
Load bearing partitions must always be mounted off the subfloor beneath the floating floor, see
figure 5 & 6. This detail may also be used to subdivide the floating floor surface as described in
section 2.
For Concrete Floor Installation:
Perimeter battens should be used where the flooring
abuts a partition.
Where non-load-bearing partitions are to be mounted on the finished floor, install a double row
of Profloor Excel Battens along the line of the partition. See figure 7 & 8. Particular care must
be taken in the batten layout. Alternatively, use short lengths of Profloor Excel Batten as noggins
between adjacent battens, at centres to suit flooring board thickness, to create a ‘ladder’ under
the partition line. See figure 9 & 10.

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.
For Timber Floor Installation:
Apply a line of Profloor Adhesive to the top of Profloor Excel 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 plasterboard plank. Apply Profloor Adhesive to the tongue and groove joints of all
flooring boards before fitting them together. No further fixings are necessary, but if required,
preferably screws (or annular ringed shank nails) may be used in the normal manner*.
Remove any surplus adhesive from the surface before it dries with a damp cloth. Adequate
gluing will help reduce potential squeaks. See figure 11.

For Concrete Floor Installation:
Apply a line of Profloor Adhesive to the top of Profloor Excel Battens prior to installing the
flooring boards. Apply Profloor Adhesive to the groove joints of all flooring boards before
butting them together and fix in the normal manner* preferably using screws (or annular
ringed shank nails). 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. See figure 12.
*Seek the advice of the flooring board manufacturer for details of fixings.
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. The rate of expansion / contraction will depend on the moisture content of
the boards, laying conditions and the length of run. Movement joints should be incorporated
in long turns e.g. long corridors check with manufacturers for advice. Boards should be
conditioned in the environment they will be used prior to installation.

EXPANSION OF FLOORING MATERIALS
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 13, 14 &15.
