Installation Procedures

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

General Installation Guidelines

  • To ensure a high standard of finish, it is essential that the supporting structure is accurately constructed. Warped, twisted or poor quality timber, or badly erected steelwork will reflect in the finished surface and can cause damage to the product.
    The structure must be checked and adjusted as necessary to ensure that there is no bowing or distortion which could affect the true plane of the final application.
  • For maximum spacings between supports for Nutec flat sheets, refer Table 1 and Fig. 9 for guidelines.
    Sheets should not be fixed directly onto a masonry wall, but on timber or steel battens forming a framework to which the fascia boards or sheets can be fixed.
  • Holes for fixing must be set out evenly and must be drilled and not punched.
    An ordinary hand drill and steel drill bits specially sharpened to a 20° angle are recommended.
    The drill bit must be 2 mm larger than the diameter of the fixing bolt or screw.
  • When the sheets are fixed into a framed structure allowance must be made for thermal movements in the sheet and the supporting structure.
    The allowance for movement will depend on the size of the sheet, but an average can be accepted as ± 2 mm per metre in both directions. For facade jointing, use recommended jointing details.
