Autex Greenstuff is NZ's leading brand of polyester insulation made in New Zealand. This product is formaldehyde free and made with up to 70% recycled PET (eg. recycled coke bottles).

Polyester is very easy to install made from the same material as duvet inners (no respiratory and itchy side effects that some people experience with fibreglass) and staples up easily using standard staple gun. These can be installed using between the joist method or stapled to underside of joists as shown in photo to create a complete thermal envelope.

Full instructions provided. No experience necessary. Anyone can do it and results are instant.

Polyester underfloor insulation does not hold moisture (so timber can breath) or require electrical wiring to prewrapped (to prevent fire risk) like other underfloor products.

Also acts as a remarkable sound absorber even underfloor making your home quieter and more cozy feeling.
