About EnviroWool Ltd

A new generation of insulation Envirowool® is pure, loose wool and brings a wealth of unique benefits only this natural fibre can. As well as its great insulation and sound proofing qualities, Envirowool® is free of formaldehyde; it's also non-allergenic and naturally flame-resistant.

Wool has been synonymous with optimum warmth for centuries, yet when people think "home insulation", man-made, synthetic products still jump to mind. That's all changing, and we're among those leading the charge with Envirowool®, one of the very few, pure wool insulation products around.

For existing homes and buildings where insulation removal's needed, we use a powerful, purpose-built extraction system to safely and cleanly "suck out" old insulation. Then, we put our custom-designed installation machine into action, blowing wool into the roof space.

Envirowool® is a premium product, and we only use the best for installation. All jobs are scoped and overseen by a tradesperson to ensure great results every time. Insulating a ceiling cavity that has existing problems, like rotting wood, exposed wiring or insect infestation, with any product is fraught - that's why an important part of our initial assessment process includes a pre-installation inspection.

Simply put, insulation provides a barrier by reducing the transfer of heat. When it comes to uninsulated or poorly-insulated homes and buildings, most of the heat disappears through the ceiling - Envirowool® alone can stem up to 40% of a homes heat loss, producing a difference you'll actually feel: snugglier, healthier and drier.

Benefits of insulating include:

  • A warmer, healthier home or building
  • Better health and fewer sick days
  • Greater comfort
  • Reduced damp and condensation
  • Cools in summer, warms in winter
  • Lower energy bills
  • Better re-sale on your property
  • Lower greenhouse gas emissions

We service the whole of Southland & Otago. Please visit our website for more information, then give us a call or complete our online enquiry form to discuss all your insulation requirements today.
