|Something that Aotearoa has an endless supply of is sheep. That is why this insulation material – essentially a by-product of one of our biggest exports – is not only a sustainable material option, but a regenerative one.|
And it works, really well! The complex design of wool fibre has beneficial properties and advantages you won’t find in other insulation.
Wool is renowned for its natural ability to regulate temperature and its exceptional thermal properties. The insulating fibre also provides superior noise control and enduring value.
How does it work?
The following text is derived from Terra Lana:
Wool breathes. The material is very effective at blocking the transfer of heat by trapping air within and between the fibres.
The cellular structure also enables the absorption and release of water vapour – known as ‘breathing’- which drives moisture away from insulated spaces making them drier, easier to heat and more comfortable.
The ‘breathing’ process can also help to moderate internal temperature, as energy in the form of heat is released from moisture vapour transfer.
Wool can uniquely maintain its insulative performance even when it’s damp (even with up to 30% of its weight in moisture, it still won’t stop keeping you cosy.)
You’ll have a warmer, drier home through winter, cooler during summer.
Wool is a very durable material that resists biodegrading until composted. Some suppliers even stamp their products with a 50-year warranty!
Brands such as Terra Lana use a blend of NZ wool for supreme performance, combined with polyester to add rigidity, so it stays in place, keeps its loft and continues performing to spec.
- Environmentally friendly
- Safe & healthy
- Natural & non-toxic
- Absorbs building toxins
- Superior acoustic performance
- Enduring value
- Saves on energy
- Local (to the kiwi market at least 😊)
Wool’s ability to regenerate itself – on sheep – and return to the earth safely after its use period keeps it rooted to our environment. It’s our responsibility to reduce our impact on the environment, so let’s keep it local and add wool insulation to your next project!
