Wool Insulation NZ: Why We Choose Terra Lana for Warmer, Healthier Homes
If you’ve ever been through a South Island winter in a cold house, you’ll know what matters most: a home that feels warm, dry, and comfortable — without huge power bills.
That’s why insulation is one of the biggest choices you’ll make when building.
At Whio Homes, we use Terra Lana wool insulation (made in Christchurch from local farmers) because it delivers the everyday benefits people actually care about — and it fits naturally with our Foreverbreathe™ approach to building warmer, healthier, lower-toxin homes.
Warmth you can feel (and bills that stay sensible)
Sheep thrive in both freezing winters and hot summers thanks to their wool. That same natural design makes wool insulation one of the best-performing options for NZ homes.
It has Excellent thermal performance keeping your home warmer in winter and cooler in summer. It reduces heat loss and helps keep indoor temperatures more even, so your heater doesn’t have to work as hard or as often.
Quieter, Calmer Living
Terra Lana wool insulation doesn’t just trap heat — it also helps with soundproofing. Wool absorbs sound waves, reducing noise transfer between rooms and from outside. The result is a quieter, calmer home environment.
