There's a sensible way to fund warmer windows. Here are the reduced-rate bank loans that cover double glazing, why the spend pays you back, and how to phase the work over time.
Bank energy loans
Several New Zealand banks now offer reduced-rate or interest-free loans for energy-efficient home improvements, and double glazing qualifies. Here are the main programmes worth asking about. Each sits below a standard personal-loan rate and is written to cover work like window upgrades, and your own bank likely offers something similar.
Your investment
Quality windows are one of the smarter things to spend on at home, because the gain keeps coming back. Low-E double glazing in thermally broken frames can cut heat loss through the window by up to 73%* against single glazing in a standard frame, and a quality aluminium window is built to perform for 25 years or more. The upfront cost is offset by lower power bills and a warmer, drier, quieter home for decades.
Indicative figures only. They are derived from typical industry U-values rather than testing of a specific Lume unit, and describe heat loss through the window itself, not a total household energy saving. Actual performance depends on window size, glass configuration, frame type, install quality and your home's conditions. Certified performance data for your specified joinery is available on request.
Staging the work
Not ready to do the whole house at once? We can prioritise the rooms you live in, living spaces and bedrooms first, and phase the rest over time, so you feel the benefit where it matters most without committing to everything upfront.
