K11 RIGID SHEET FLOORING/SHEATHING/DECKING/SARKING/LININGS/CASINGS

295 FLOATING FLOOR SYSTEM:

H & H Floating Floor Systems.
A range of high performance acoustic overlay flooring products designed to reduce impact noise passing through floors with minimum loss in room height.
If the floor is to be used as a deck for smooth floor finishes, minor sanding of the joints may be necessary before applying the floor finish - fully flexible materials to BS: 3261 A should be used. Where a good quality, smooth finish is required, it may be necessary to fix 6 mm hardboard or plywood on to of the floating floor, using a contact adhesive.
When laying laminate floors, loose lay a 2-2.5 mm P.E. foam material between the laminate and the floating floor.
Smooth floor finishes such as ceramic tiles, marble, limestone and other specialist floor products may be laid over the floating floors - discuss requirements with H & H technical Department and the floor finish manufacturer.

Apply Reduc Joint Adhesive to the joint, using one litre/25 m² of floor area laid. Push the second board into the joint to form a tight fit with the first board and repeat along the length of the wall. Cut the last board to fit.
Stagger joints on the second and subsequent rows, applying Reduc Joint Adhesive to each tongue. Ensure all boards fit tightly together to avoid gaps and sound leakage from flanking transmission and fill any other airgaps with FlexiSeal.
Provision for services:
Cut boards around sanitary fittings, pipes etc., ensuring the boards do not come into direct contact with the fittings. Fill gaps with FlexiSeal. Alternatively, fix the sanitary ware on a 35 mm wooden plinth and cut the Reduc Strata to butt up against the plinth, filling any gaps with FlexiSeal. If access to ducts and services is required, cut an access trap by setting a power saw at 45° and at a depth to suit the boards. Replace the trap by laying a bead of FlexiSeal.
Finishing:
Allow up to 48 hours for the adhesive to cure before walking on the floor.
Fix skirting boards, if required, allowing a 2 mm gap between the bottom of the skirting and the top of the Reduc Strata. Sand down the board joints before laying smooth, flexible floor finishes.

Reduc Strata Extra.
A high performance acoustic overlay flooring product designed to reduce impact noise passing through new and existing timber and concrete floors.
The top layer of moisture-resistant, medium density fibreboard is isolated from a layer of dense cement particle board by visco-elastic sound damping strips. The underside facing incorporates a resilient layer of acoustic felt, which provides mechanical isolation from the existing floor structure. The moisture-resistant upper surface allows the overlay to be used throughout the building, including kitchens and bathrooms, and the acoustic felt will contour over minor irregularities in the surface of the concrete floor being treated. Do not construct either load bearing or non-load bearing partitions off the Reduc Strata Extra floating floor system.
Additionally Reduc Strata Extra can be specified in conjunction with 100mm Sound Slab Insulation Boards. The insulation material is required to be fitted between the timber joists of the floor. This can be achieved by removal of existing ceiling finish and fitting from below, or by removing existing floorboards (two in every six). The floorboards must be replaced prior to installation of Reduc Strata Extra.
Characteristics:
Dimensions: 1175 x 575 mm.
Thickness: 35 mm.
Weight: 27.9 kg/m².
Operating temperature: Designed for use at normal building temperatures.
Fire performance: Will not add significantly to any existing fire hazard when properly installed. When used in conjunction with FireFloor 25 mm gauge wire mesh and SoundSlab one hour fire resistance will be achieved with lath and plaster ceilings and 12.7 mm plasterboard ceilings when tested in accordance with BS 476: Part 8: 1972 - a copy of the fire certificate (FR 907) is available on request.
Acoustic performance: See technical literature for typical floor constructions.
Reduc Strata Extra acoustic flooring overlay products have been awarded British Board of Agrément Certificate No. 92/2826.
H & H can provide technical support with all aspects of acoustic performance requirements and can prepare specifications and effective installation instructions to ensure optimum acoustic performance is achieved. Pre- and post-installation testing for airborne and impact sound insulation can also be carried out if required. Contact H & H for further details.

Substrate: Concrete floor / Timber floor.

Accessories/Other requirements:
Acclimatise Reduc Strata Extra boards in the area of use for 24 hours prior to installation. When cutting boards, wear a suitable facemask to avoid the inhalation of dust. Remove existing skirting boards, as necessary.
Previous to installation:
Remove existing skirting boards, as necessary.
Optional if SoundSlab Insulation is to be included:
Take up the existing timber floor as necessary and fit 100 mm thick SoundSlab insulation between timber floor joists, covering the whole of the ceiling area, including any gaps between the end joists and the wall. Replace existing timber floor, renewing boards as necessary.
Or:
Remove existing ceiling and fit 100 mm thick SoundSlab insulation between timber floor joists, covering the whole of the ceiling area, including any gaps between the end joists and the wall. Support the insulation with FireFloor Wire Mesh nailed to the sides of the floor joists, before installing new ceiling boards.
Ensure the existing floor is structurally sound and free of creaks. Remove any protruding nails or carpet tacks so that the floor is flat and level. On concrete floors, ensure the floors are flat and dry and apply a suitable smoothing compound or levelling screed if necessary, in accordance with the manufacturer's instructions. Ensure that any smoothing compound or screed is dry and the surface of the base of the perimeter walls is smooth, flat and free from dust or loose particles.
Fix 37 mm Reduc Isolation Tape around the bottom vertical face of all perimeter walls. If the surface of the wall is uneven, apply a 5 mm bead of FlexiSeal at the joint between the floor and the wall.
Installation:
Remove the tongue from the long and short edge of the first board to be laid. Starting at the opposite corner from the door opening, lay the first board felt side down against the Reduc Isolation Tape or FlexiSeal bead, ensuring the board does not come into direct contact with the perimeter walls.
