Wool Is Warmer

Wool has a complex natural cellular structure that provides superior warmth in all climates, as it buffers temperature changes. Like wearing wool clothing, it improves the comfort of our homes and requires less energy to heat or cool them than synthetic insulations.

Wool is one of New Zealand’s greatest renewable resources. Our new wool is sourced from local Canterbury farms, and our recycled wool from carpet manufacturers’ pre-consumer waste. All Terra Lana offcuts can be returned and recycled in our low-carbon manufacturing plant.

Healthy & Safe

Builders love Terra Lana insulation because it can be handled without protective clothing. There are no nasty ingredients and it’s been tested to ensure negligible VOC emissions. Terra Lana wool insulation is the healthy choice for your family and the environment.

Moisture control

Wool is hygroscopic, which enables the absorption and release of water vapour. This natural phenomenon, together with its moisture-wicking properties, helps to reduce the risk of interstitial condensation and mould forming within buildings whilst still maintaining thermal performance.

Wool has a natural crimp to its structure, which provides excellent acoustic properties. Testing provided by Marshall Day Labs has proven Terra Lana insulation reduces noise transfer through walls, floors, and ceilings of residential and commercial buildings.

Our wool insulation comes with a 50-year warranty to meet the durability requirements of the New Zealand Building Code. The combination of New Zealand wool and thermal bonding technology using polyester creates a robust, structurally stable product that will never slump nor lose its loft over the lifetime of the building. You can be confident that just like wool, Terra Lana insulation will stand the test of time.

Return & Recycle


We operate on a Zero Waste policy here at Terra Lana using a 'closed-loop' manufacturing model.

No more insulation in landfills—Terra Lana wool insulation offcuts can be returned to our specialised factory where we recycle them back into acoustic insulation.
