Coastal South Island Windows and the Cost of Getting Corrosion Wrong

Salt does not forgive mistakes.

Coastal South Island environments accelerate failure when coatings are wrong or detailing is poor. Most corrosion issues are not material failures. They are specification failures.

Common causes include:

• Incorrect coating class.

• Incompatible fixings.

• Poor drainage at junctions.

Steel and aluminium both perform when specified correctly. Both fail when shortcuts are taken. Maintenance plans matter. So does access.

The cheapest window is often the most expensive over time.
