3 Preface Preface for Australian Installation These guidelines are to be used in conjunction with the following standards: a. AS/NZS2455.1:2007 Textile floor coverings - Installation practice: Part 1 - General b. AS/NZS2455.2:2007 Textile floor coverings - Installation practice: Part 2 - Carpet Tiles c. CRI Carpet Installation Standard 2011, First Edition d. BS 5325 Installation of Textile floor coverings - Code of practice Carpet Tiles Acoufelt carpet tiles are a flexible floor covering perfect for modern living and working environments. They are hard-wearing, practical and versatile while providing an essential basic function in buildings with enriched decorative qualities. With easy installation and cleaning as well as long life usage, you have the perfect solution for carpeting all types, shapes and sizes of rooms. Floor Requirements Acoufelt carpet tiles are intended for internal installations on dry floors and stairs. The product is not suitable for installation on walls or wet surfaces. Before installation, the surface must be clean, dry and free of dust. The floors must be properly cured, level and smooth. The installer must measure the area to be carpeted and plan the layout, keeping in mind expected patterns (a quarter-turn, stair step, straight or other pattern) and placement of tile for best appearance and maximum wear. Additionally, when installing carpet tiles, we suggest only pressure sensitive adhesive is used. Using the recommended adhesive (see page 6) to install the carpet tiles, prevents loose lay carpet tiles from moving under traffic conditions, but enables them to be replaced easily when required. High performance, solvent free adhesives are designed for installation over wood and concrete subfloors. Using the recommended adhesives can also reduce the cost of future removals without disturbance to the subfloor. 2

4 Tile Installation Step 1 Find the centre line in the installation area by using crossed diagonals. The installation process will begin with the centre of the room. Find out the side of the longer wall and mark out a line parallel to the longer wall running through the centre C (AB). Now mark a line (DE) and (AB) passing through centre (C). Step 2 Use a V1 notched trowel (1.6mm deep x 1.6mm wide) to spread the adhesive evenly. Allow the pressure sensitive adhesive to dry clear (dry tack) first before laying the carpet tile. A stronger bond, if required, can be achieved by laying the tile into the adhesive film prior to it drying completely. This will cause transfer of the adhesive film onto the back of the tile. A C D B NB. The adhesive is to be spread to all floor areas to be covered by the tile, including the very perimeter of the floor adjacent to the walls. Failure to place adhesive on the floor at the junction of the wall and floor may result in cut pieces constantly coming loose and becoming unsightly. E Wet (Green) Slab * Installations Full Spread - As per the above instructions when using an approved adhesive specially formulated for wet (green) slabs (refer to page 8). Picture Frame - Adhesive application (grid installation method) if non-wet slab adhesives are used. Minimum width for adhesive lines must be 30cm. The lines must be centred under tile joins with a minimum of 10cm either side of the tile joins. * Concrete or sub-floor relative humidity (RH) up to 99% (as measured by ASTM F Standard Test Measure for Determining Relative Humidity in Concrete Floor Slabs Using In-Situ Probes) for no longer than 6 months from date of installations. 50cm minimum 30cm minimum 10cm 3

5 Step 3 Directional arrows are on the backing of each tile. Determine the arrow direction before the carpet is installed. This arrow allows for one-directional or multi-directional installation. Some styles may be linear in design and require quarter turning. For the recommended installation method of your particular Acoufelt carpet tiles please refer to the product specification document on the required carpet range. Step 4 Use of the Pyramid method of installation is strongly recommended for the best installation result. Begin by laying tiles from the room s centre and work toward the walls, creating a stepped pyramid. Accurately lay the tiles and have them butted together by hand, continue this process until you reach the walls. NB. Do not use mechanical methods to push the tiles together (eg kneekicker). This will only create tension in the tiles and result in peaking at the joins. The tiles are dimensionally stable and should not be squeezed. Monolithic Quarter Turn Vertical Stair Step Vertical Brick Random Horizontal Stair Step Horizontal 1/2 Brick Some Useful Measurements Acoufelt backed carpet tiles are engineered to be dimensionally stable in commercial flooring environments and conditions. As such, they will not change shape. Therefore it may be useful during the installation to intermittently measure the results of your installation. Typically there will be a very small gap between the backing of each tile (approx.0.5mm), a result from the butting together of the carpet pile. So from the surface it will appear as a smooth join, but at the level of the sub-floor, there will be a very small gap. Running a tape measure over 11 tiles (10 joins), the distance should be the width of the tiles + 0.5mm (approximately) x 10 = 5005mm. If the measurement is less than this, then the installation may be too tight and peaking may occur. To correct, you would need to uplift and re-lay, so a habit of regularly checking the measurement may save much time and cost later. If the measurement is greater than this, the tiles may be too loose and gaps may visually start to appear - this may also lead to ragged edges on individual tiles. To correct, you would need to uplift and re-lay - napping of ragged edges may also be required. Stairs Installation Stairs Installation Acoufelt tiles can be installed on stairs. It is highly recommended that separate pieces be cut and applied to the step & riser, the junction being covered with an appropriate Nosing for both aesthetics and safety. Size of cuts and types of Nosing will depend on the style of stairway and the type of environment 4

6 Product Warranty Acoufelt provides a limited warranty from the date of installation against undue loss of condition due specifically to faulty materials and workmanship in carpet manufacturing. Our warranty covers the following: Installation Environment This product is designed for indoor use in typical commercial office type environments. Use in areas that significantly vary from this type of environmental condition may result in a performance that falls outside of this warranty. Specifications The product will conform to the established specification subject to normal manufacturing tolerances. Wear Warranty The product is warranted against excessive surface wear and backing tear under normal use. Excessive surface wear means loss of more than 10% by weight of face fibre within 15 years. De-lamination The product will not delaminate for its carpet life. Acoufelt recommends chair pads for optimum surface appearance retention performance. Dimensional Stability The product will retain its stability and any dimensional changes due to normal atmospheric conditions will be within international tolerance as measured under test method BS EN986:20 for the life of the carpet. Static Control The product will, for the life of the carpet, remain shock-proof and will generate static below 3.5 KV when tested under AATCC 134 standard. Resistance Against Water/Liquid The product will not lose its usability with effect from liquids excluding corrosive liquids for usual activities. Zippering The product will not zipper or create yarn running effects for the life of the carpet. Wet (Green) Concrete Slabs Current building practices may result in the need to install Acoufelt cushion backed carpet tiles over a so-called wet slab. Due to the ability of moisture to evaporate through cushion backed carpet tiles at normal room conditions (60% RH and 20 degrees C), high ph or moisture levels are unlikely to exist for extended periods at the concrete surface. Provided the approved alkaline resistant adhesive (see Installation Instructions) is used per the adhesive manufacturers instructions, and the carpet tile is installed per our installation instruction, odours (2-ethylhexanol) resulting from the interaction of high ph and Acoufelt cushion backed carpet tiles will not occur. 5

7 This warranty excludes any consequence of faulty or improper installation or faulty maintenance and is subject to the following conditions and exclusions: 1. Installation must be in accordance with the current Acoufelt Installation Guide. 2. The product is subjected to normal wear and tear. 3. Shading is the result of pile reversal where areas of the carpet may appear to have changed colours. This is a feature of fine carpets. It is not a manufacturing fault nor does it have an effect on durability. 4. Local spillage must be attended to as and when it occurs. 5. Mould, fungal or bacterial growth resulting from damp being retained for any reason within the carpet system or structure is excluded. 6. A full maintenance program is agreed and carried out throughout the life of the product. Please refer to the Acoufelt Carpet Cleaning and Maintenance Guide. 7. It is imperative that all internal carpets are well protected from outside soiling and moisture by the use of barrier matting. 8. If a product fails to perform as warranted, Acoufelt will correct the affected area either by repair or (at its option) replacing the defective part of the carpet tile/s with an Acoufelt product of equal quality, or (at its option) pay for the cost of replacement of the defective part of the product. 9. Should replacement of any Acoufelt products be required, Acoufelt will not be responsible for the movement of electrical wiring or outlets or costs and expenses associated with construction or removal of furniture, partitions, temporary walls or any other fixtures, fittings, plant or equipment whatsoever which are located on, above or around the area in which the product is installed. 10.
