Fire-Rated Windows and Doors. Where Projects Commonly Go Wrong.

Fire-rated joinery is a system, not a component.

Steel performs well under fire exposure. Slim profiles remain achievable with tested assemblies. Fire ratings apply to the complete build-up. Frame, glass, seals, and fixings must match test data.

Common mistakes include:

• Mixing untested components.

• Late fire separation changes.

• Treating fire joinery as standard windows.

In South Island apartments and mixed-use buildings, fire-rated windows often sit on critical paths. Early specification protects programme and budget.

Fire performance should be resolved before layout is locked.
