Innovation built on experience

Profloor Dynamic Strip


Significant improvement in Impact Sound Insulation can be obtained when using Profloor Dynamic Strip System under the chosen floor finish.

The use of Profloor Support Strip is recommended around the perimeter of all rooms and in areas such as bathrooms and kitchens where the load could exceed 1.4kN/m2.

The third element of the Dynamic Strip System is the use of a 5mm Profloor Flanking Strip to isolate the acoustic floor from the walls and skirting boards.

Key Features

  • Covered by BBA
  • Foams do not degrade over time
  • Lug fixing eliminates risk of nails penetrating foam when being fixed
  • Suitable for situations where battend epth would reduce ceiling-to-floor height
  • Foam resistant to biological attack
  • Improves impact sound primarily, but can also improve airborne sound
  • Fixing lugs reduce the risk of timber-to-timber squeak
  • Dynamic Strip and Support Strip are colour coded to avoid confusion
  • Foams will not delaminate if exposed to moisture


  • Ideal for both new build and refurbishment
  • Significantly reducesimpact and airborne noise pollution in multi-level buildings
  • Supremely versatile, making it suitable for most domestic flooring applications
  • Easy and fast to install to wooden joisted floors
  • No wet trades involved
  • Floors can be used immediately after installation
  • Warmer floor surface
  • Designed to last the lifetime of the floor
  • Non-load bearing partition walls can be erected on the finished acoustic floor where a double run has been positioned below.

Installation details

1. Sequence

It is normal practice to fix the ceiling before the floor.

2. Heavy Pugging Floor

In the ribbed floor with heavy pugging, a ceiling of two layers of plasterboard, with the joints staggered, to a total thickness of 25mm is fixed through the 6mm plywood to the timber joists.

A minimum of 80kg/m2 pugging is placed on top of the plywood. Advice on types of pugging material can be obtained from our Technical Department.

Further improvement on airborne transmitted sound insulation can be achieved by laying a 19mm plasterboard plank between the Profloor Dynamic Strip and the floor panels.

The floor finish can be chipboard or T&G flooring. The flooring should be isolated from the structure using Profloor Flanking Strip.

3. Absorbent Quilt Floor

The ribbed floor with 100mm absorbent material, is placed on top of a ceiling of plasterboard, with joints staggered, of a total thickness of 30mm.

Ensure that no gaps are left between the absorbent material.

The floor finish can be P5 chipboard or T&G flooring on 19mm plasterboard plank. The flooring should be isolated from the structure using Profloor Flanking Strip.

4. Fixing Dynamic Strip to joists

The Profloor Dynamic Strip is laid, foam side on the joists and fixed using the fixing lugs provided, with nails or staples.

5. Fixing Floor Finish

In a ribbed floor with quilt extra mass may be required. Apply Profloor Adhesive to the top surface of the Profloor Dynamic Strip.

Lay 19mm Plasterboard plank across Profloor Dynamic Strip, ensuring that all board ends rest centrally on a joist, and apply Profloor Adhesive to the surface before placing the final floor finish panels in position.

Care must be taken to avoid damaging the plasterboard plank prior to the application of the final floor finish.

6. Gluing Tongues

Profloor Adhesive should be applied to the tongues of all wood flooring panels before fitting them together. Any surplus adhesive should be removed from the surface before it dries.

7. Wood Flooring Panels

To ensure stability in the finished floor where the wood flooring panel is applied direct to the top of the Profloor Dynamic Strip, it is recommended that a timber support batten is used between joists where floor panels join mid span. Alternatively use a plywood glued to Profloor Dynamic Strip below floor finish.

Where access below the flooring system, is required the necessary hatch can be cut in the floor finish material. Additional strips should be placed round the perimeter of the hatch to support the main floor and the hatch cover. This may require additional timber noggins.

8. Skirting

Fold the Profloor Flanking Strip onto the floor board, 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. This operation will ensure that the integrity of the floating floor is not affected by flanking transmission.

9. Partitions

If new or additional partitions are required, advice must be sought, from the manufacturer, prior to laying if the design requires that these be taken off the finished floor.

10. Kitchen/Bathroom

When a concentrated floor loading is in excess of 1.4kN, ie. (under bath, WC, Kitchen unit or night storage heaters) a Profloor Support Strip can be supplied for use in small local areas. Additional noggin support may be required.

The Profloor Support Strip will give the same finished floor level, under the loaded floor, as the standard system under normal loading.

11. Fire Stops

Care should be taken at the design stage to ensure that the fire stops are fitted to the same standard as that required for the Fire Doors. Technical advice can be provided for individual projects.

12. Protection

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