Product Performance...

All Bradnam's products comply with the 15 year durability requirement of the Building Act 1991 B2.


Product Testing

Altus has its own IANZ Accredited testing laboratory to ensure designs meet local and overseas standards.

The development process for all Bradnam's products begins with excellent, well-researched window and door designs, which undergo stringent tests for strength, air infiltration, diflection, operation of opening sashes, dimensional accuracy and water leakage to meet New Zealand Standards. All Bradnam's products meet or exceed the wind loading ratings set down by the New Zealand Building Code.
