1 OUSTI FLOORING SYSTEMS 30, K30, 40 & 60 The versatile cradle and systems with unique, patented, recycled, rubber crumb cradles comply with Robust Detail FFT2. Widely used where Pre-ompletion Testing is required and in conversion/refurbishment and new build projects, these systems can be levelled on site to eliminate variations in the structural floor surface and can accommodate services.

The cradle base packers may be used in multiples to achieve the desired finished floor height. Deeper s are generally used in larger projects and where a consistent high void is required.

4 INSTLLTION INSTRUTIONS FOR OUSTI FLOORING SYSTEMS 30, K30, 40 & 60 The following instructions are issued as an aid to the correct installation procedures. Individual site conditions may necessitate variances to these standard instructions. Such cases should be referred to the Instaoustic Technical Department for approval. ll installation and working practices should be in accordance with relevant odes of Practice, current ritish Standards and HSE Regulations applicable to the construction industry. 1 2 DMP PROOF MEMRNE (OPTIONL) damp proof membrane is recommended on ground floor slabs and new concrete bases above ground level. (See Points to Note and Site Preparation) TTEN ENTRES Start, usually at the point furthest from the doorway (wall ), by measuring out the perimeter centres (Fig. 1). For example, for the 40 system, mark out every 400mm to give the centres. Mark out the perimeter centres on the opposite wall (wall ) and, using a chalk string line, ping or mark between the matching marked points (Fig. 2).

The cradle centres vary according to which is being used. For example, for the 40 system with a deep the cradles will be at 600mm centres. Using this example, measure 600mm along both and D perimeter chalk lines, starting from the same end (e.g. wall ) and mark or ping a chalk line between the corresponding points to create a grid (Fig. 3) RDLE POSITIONING Place the cradles around the perimeter on all the marked points, ensuring a gap is maintained between the wall and the cradle edge, and at each chalk line intersection (Fig. 4).

The cradle packers should be placed in line with the direction of the s. When packing under the join of two or three s make sure the packer is supporting all s. Packers can be used to a maximum of below the top of the cradle. dditional height can be achieved by using and 30mm cradle base packers. TTEN PLEMENT Insert the cradle s into the cradles. Start around the perimeter and then along the original marked ping lines. s should be laid in a staggered formation and all s must join within a cradle. (Fig. 6) OUSTI INSULTION (OPTIONL) If required, the acoustic insulation should be laid between the cradle s.

Edges on the short side of the boards must join on a. The boards are screwed down using countersunk wood screws as in the screw fixing pattern, Fig. D below. Perimeter fixings on the long edge of the boards should not exceed 600mm. Fixing centres along the cradle s should be at 300mm and 150mm from the long edge perimeter. Where boards join on the short edges they should be screwed down in two places both sides of the join. RESILIENT FLNKING STRIP gap between the edge of the chipboard and the perimeter wall must be maintained. fter the chipboard has been laid throughout the room insert the Resilient Flanking Strip into the gap. Ensure that this flanking strip is continuous around the perimeter.

Tongue & Groove of boards glued and boards glued to timber s Points to note MEMRNE (IF REQUIRED) membrane, such as 1200 gauge polythene sheeting, should be installed over all ground floor slabs and new concrete bases above ground level. Joints shall be lapped a minimum of 150mm, and should be taped and sealed with waterproof adhesive tape, with edges upturned to the same height as the tongue & grooved overlay boards at all perimeter walls. SERVIES If there is insufficient room to run services beneath the s, services may be accommodated by cutting the s, and passing the services between the cut s (See Fig. on page.29). Support the cut, leaving - 1 clearance from the service, with additional cradles supporting the cut s. Never notch the s. Services running at the perimeter of the room must be a minimum of 150mm from the perimeter, and should not be grouped any wider than the available space between the s. OUSTI INSULTION coustic insulation is recommended with concrete planks and beam and block floors and will give an improved airborne noise performance from the system. It will also take account of any inadequacies in the sealing and grouting of the sub-floor. INTERMEDITE ORD SUPPORT When the short ends of the boards do not join on a, they should be supported with intermediate cradles and s, (see Fig. ). Where boards join without being tongued and grooved, such as in doorways, support the join with intermediate cradles and s. Screw and glue the boards to the with a gap between the edges of the boards to avoid squeaking. atten spacing may be adjusted to suit room sizes to minimise waste provided the maximum spacing is not exceeded. NORML LODING If the cradle and system is to be subjected to abnormal loading, it may require the use of hard and/or additional cradles. In such cases please refer to the Instaoustic Technical Department for advice. EXPNSION JOINTS Expansion joints may be required in long corridors, please refer to the Instaoustic Technical Department for assistance.
