All products supplied by First Windows & Doors meet or exceed the requirements of the New Zealand Building Code and New Zealand Standards; NZS4211, Performance of Windows, and NZS4223, Glazing in Buildings - Parts 1-4 incl.


This means our windows and doors have been designed and successfully tested to perform in New Zealand’s most diverse conditions, and will:


  • satisfy the strength and deflection requirements of the standards
  • deliver the desired levels of weathertightness appropriate to the prescribed wind zones
  • meet the air leakage requirements necessary to provide comfort and efficiency
  • include glazing of appropriate weight, strength and safety to satisfy not only the expected wind load but also accidental human impact.


In accordance with the TERMS AND CONDITIONS OF WARRANTY, a warranty for all First Windows & Doors products is provided, under normal conditions of use, against failure of materials and/or workmanship for a period of 5 years from the date of practical completion.


The surface finishing of the aluminium extrusion is covered by a separate Performance Warranty which is dependent on the actual finish selected.


A window and door hardware/component warranty protects against defects in manufacturing, functionality and surface finish for a period of 5 years, provided care and maintenance guidelines have been followed. Plated (soft) finishes are excluded from the warranty.
