        Installation & Maintenance-(1)

        Fecha:Jul 13,2011


        It is the responsibility of the ceiling contractor to ensure that materials delivered to the installation site are safeguarded from the time of purchase until the finished ceiling is handed
        over. However, it is usually the main contractor who is responsible for the conditions on site and so both parties must be aware of the requirements of suspended ceilings for flat, dry, clean and safe storage conditions.
        Armstrong packaging of ceiling tile and grid varies from material to material, but all is designed to withstand careful site handling. However, poor or rough handling, rolling or dropping of cartons
        on their corners or edges may cause damage to the product or the product to deteriorate, irrespective of the material. Long grid and trim cartons should not span between points as any load applied mid-span may cause product damage.
        Mineral fibre tiles are packed as cartons with a cardboard sleeve and then shrink-wrapped; however the shrink-wrapping is not waterproof. Grid sections, soft fibre tiles, wood veneer tiles and metal tiles are all packed in full cardboard cartons.
        Cartons of mineral fibre and soft fibre tiles should be stored and stacked with the tiles face up (horizontally) and without any other heavy objects on top of them.
        Cartons of wood veneer and metal tiles should be stored with the tiles standing on their sides (vertically).
        All cartons may be stacked on wooden pallets and secured with shrink-wrapping for transportation but when on the installation site they should never be stacked higher than when originally delivered to the site.
        Consideration should be given to the advice of the Health & Safety Executive (HSE) regarding the manual handling of heavy cartons. An assessment should be made of any associated risks and if
        necessary mechanical lifting equipment should be used.


        Installation of Armstrong ceiling tiles should be conducted in the appropriate site and environmental
        conditions as described above and as per Armstrong’s manufacturer’s recommendations (see pages 42-43). Due consideration should be given to the relevant British and European Standards, COSHH and health & safety regulations and the use of the correct personal protective equipment (PPE).
        Cartons should be opened carefully with the cardboard sleeve on mineral fibre cartons released to ensure that tiles can be removed without damaging the edges of the tiles.
        It is recommended that mineral fibre tiles are cut with a sharp knife.Unnecessary breakage of tiles should be avoided. Newtone, Madera wood products and Axiom aluminium extruded sections are best cut using a powered saw with the correct blade for the material.
        Metal tiles are painted with a highly durable polyester powder coat finish which provides a paint surface that does not readily chip, crack or flake as can be associated with ‘wet’ paint
        finish to metal tiles. Metal tiles will often need to be cut at room perimeters or junctions with columns and when this is necessary it is important that a flat clean cut edge results. This is best achieved using aviation snips, electric shears, or a high speed jig or bandsaw. The cut edge should then be masked by an appropriate perimeter section and held down using wedges or spring clips as necessary.
        Care is necessary when handling and installing tiles, especially metal and soft fibre tiles, to prevent finger marking of the surface from soiled or greasy hands, and where appropriate, clean
        cotton gloves should be worn.
        Ceilings that are required to provide structural fire protection must be installed in accordance with the relevant fire test report.
