Why use NZ Double Glazing instead of Googling it yourself

Doing the research yourself means phoning around, chasing quotes, and comparing apples to pears. We do it in one form.

Licensed installers

Every installer we refer is GBI-registered and works to WANZ-certified standards. Your joinery is backed by a manufacturer warranty, not a hope.

Retrofit or new joinery

Keep your existing timber frames (retrofit) or swap the whole window (new joinery). Installers quote both so you can weigh cost vs. finish.

H1-compliant specs

Quotes include U-values, spacer type, gas fill, and low-E coating — the details that determine whether your renovation actually meets code.

Noise + condensation

If warmth isn't the priority, quotes call out acoustic glass options (e.g. airport flight paths) and anti-condensation warm-edge spacers.
