Installation Guidelines:

  • Suitable for installation onto existing builder’s upstands or with a supplied Brett Martin insulated kerb.
  • Ensure the upstand is correctly dimensioned, insulated, and weathered prior to installation.
  • Glazing must be correctly orientated, with the UV-resistant layer facing upwards (as marked).
  • When using direct-fix (sloping) method, refer to installation guide for appropriate fixings and sealing procedures.
