Profloor Dynamic Batten

Details

Profloor Dynamic Batten System is specified and detailed similar 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 and Airborne Sound Insulation can be obtained when using Profloor Dynamic Batten System in timber or 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.

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 1.4KN.

A further element of the Profloor Dynamic Batten System is the use of a 5mm Profloor Flanking Strip to isolate the acoustic floor from the wall and skirting board.

Key Features

  • Designed to improve both airborne and impact sound transmission
  • Foam will not degrade through time unlike some fibrous materials
  • Can be used on timber or concrete floors
  • Moisture resistant impregnated battens are available
  • Provides cavity for running services
  • Non-load bearing partitions can be built off the finished floor level
  • Foams are resistant to biological attach
  • Kiln dried timber battens used with moisture content under 20%

Recommendations

Mechanical fixings must not penetrate through the timber batten into the foam.We recommend that tongued and grooved flooring is bonded using Profloor PVA adhesive.

It is intended that under normal domestic load the double foam system will compress by 6mm-8mm.

Installation details

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.

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.

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 centre (max) for 22mm chipboard. 

4. Batten Stagger

Batten joints in adjacent rows should be staggered by a minimum 
of 600mm.

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. Consult the manufacturer where individual floor areas exceed 150m2 or the camber is greater than 20mm. Consider Profloor Levelling System. Advice from A. Proctor Group Tech Desk is available.

6. Mounting Partitions

Where non-load bearing partitions are to be mounted on the finished floor, install a double row of Profloor Dynamic Battens along the line of the partition.  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.

7. Fixing Flooring

The specified flooring boards should be placed length ways 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-floors: 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 buttig 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. 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.  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.

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.

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 other services. Isolate all services coming through the floor using Profloor Flanking Strip. 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 the 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*1 directly 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 door frame 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. *1Use Profloor Dynamic Batten on Timber Sub-floors.

13. Skirting Boards

Fold the Profloor Flanking Strip onto the floor board, apply weight to compress the system (Tradesmans weight is normally sufficient) and fix the skirting strip so that it rests on the flanking strip. Trim the edge of the Profloor Flanking Strip flush with the skirting.

14. Kitchen/Bathroom

(areas of increased loadings) When a concentrated floor loading is in excess of 1.5kM/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.

Tiling onto Profloor Batten Systems

The floor finish (usually chipboard or plywood) must be rigid, stable and capable of supporting additional load without flexing, for this reason it is recommended that batten centres do not exceed 300mm. Sufficient ventilation below the flooring should also be provided. Follow the installation advice given in the User Guide with respect to board fixing. There are three basic alternative methods to follow: -

1. Overlay the floor finish with 6mm (minimum) dry exterior grade plywood, which has been fully sealed. Screw down the plywood at 300mm intervals, ensuring fixings do not penetrate the resilient layer or come into contact with the subfloor (alternatively, adhere using an appropriate adhesive). Ensure all junctions are supported. Use a category C2 (flexible) adhesive.

2. Overlay the floor finish with a proprietary decoupling membrane and use a category C2 (flexible) adhesive.

3. Overlay the floor finish with a proprietary tile backer board and install following the manufacturers’ instructions. Use a category C2 (flexible) adhesive.

A CG2 (flexible) grout is recommended with all of the above methods. There are many factors to consider when deciding which method is best suited for your particular circumstances, please consult the manufacturer of the tile, adhesive & grout for further recommendations.

Tiling should be installed in accordance with BS 5385. If in any doubt, seek professional advice.
