Terra Lana Insulation
Terra Lana insulation is a premium New Zealand-made solution, blending natural wool with recycled fibres for comfort, performance, and sustainability. From 1 July 2025, government agencies must consider wool-based products in construction—further validating wool insulation as a smart, future-proof choice aligned with national sustainability goals.
Key Features and Benefits
-
Natural Moisture Management
Terra Lana insulation is hygroscopic—its wool fibres absorb and release moisture without losing thermal performance. This helps regulate internal humidity levels, reducing the risk of condensation, mould, and rot in building cavities.
-
Red List Free and Non-Toxic
Certified as Red List Free and GREENGUARD Gold, Terra Lana contains no harmful chemicals or VOCs. It's safe for installers and occupants, supporting high indoor air quality and compatibility with Living Building Challenge standards.
-
NZ Wool, NZ Made
Made in New Zealand using locally sourced wool and recycled polyester, Terra Lana supports the local economy and sustainable agriculture. Its short supply chain reduces emissions and ensures reliable quality control.
-
Naturally Fire Resistant
Thanks to its high wool content, Terra Lana insulation is naturally fire-retardant without the need for chemical additives. Wool chars rather than melts or emits toxic fumes, providing added safety in fire scenarios.
-
Designed for a Circular Future
At the end of its life, Terra Lana insulation can be fully recycled—its wool and polyester components are mechanically separated and reused. This circular design approach reduces landfill waste and supports low-impact building practices.
