🪟 Energy Savings, Warmer Homes: Why Double Glazing is a Smart Move for Kiwi Homes
Sick of waking up to wet windows, freezing mornings, and energy bills that keep creeping up?
If your home still has single-glazed windows, you’re likely losing a huge amount of heat—and money—every winter. The good news? You can now upgrade to double glazing with the help of low-interest green loans from major New Zealand banks.
At KiwiCraft Construction, we install double glazing that not only saves energy, but creates a warmer, drier, and more comfortable home year-round.
🔧 Why Double Glazing Matters (From a Builder’s POV)
A lot of Kiwi homes still have old single-glazed aluminium joinery. From a builder’s perspective, that’s like trying to heat your home with the windows half open.
Here’s what proper double glazing offers:
✅ Reduces heat loss by up to 50%
✅ Cuts condensation and moisture buildup
✅ Improves indoor air quality
✅ Adds long-term value to your property
✅ Creates a quieter, more peaceful home
“We’ve retrofitted plenty of homes in Waikato with double glazing. The feedback is always the same — warmer, drier, and way more comfortable.”
Jayson, Licensed Builder @ KiwiCraft Construction
