Benefits/Advantages

GreenStuf is completely safe and user-friendly and no protective clothing is required to handle or install the products.

GreenStuf is formaldehyde-free and does not contain any chemical binders/additives - providing safer indoor air quality.

GreenStuf will not slump or settle over time (50+ year durability rating). GreenStuf is not affected by moisture, mould or mildew, and is naturally resistant to insect and vermin attack.

GreenStuf is manufactured under strict ISO 9001 quality control systems, and is BRANZ Appraised (Certificate 380 (2000))

GreenStuf is manufactured using a high-percentage of recycled polyester fibre (from PET plastic) and is reusable/recyclable at end of life.

Composition

GreenStuf is made from 100% polyester fibres including a high percentage of recycled polyester fibre (from PET plastic), and remain fully recyclable at end of life.

GreenStuf is thermally bonded (ie. the fibres a fused together by heat) to form the structure of the insulation material. There are no chemical additives/binders (such as phenol-formaldehyde commonly used in fibre-glass insulation materials).

GreenStuf is naturally fire resistant and self-extinguishing. GreenStuf is also naturally resistant to vermin and insect attack and does not contain chemical retardants.

Technical Properties

NZBC Compliance: GreenStuf is BRANZ Appraised and will meet or contribute to the following provisions;
B2 Durability
E3 Internal Moisture
F2 Hazardous Building Materials
H1 Energy Efficiency

Fire Reaction: GreenStuf is self-extinguishing and meets all NZBC requirements.
Spread of Flame (0-10) - 0
Smoke Developed (0-10) - 3

Moisture: GreenStuf is not affected by moisture. Exposure to an atmosphere of 50ºC at 90% relative humidity for four days showed moisture absorption by weight of less than 0.03%.

Acoustic Performance: GreenStuf will assist sound reduction by reducing the resonating noise inside construction cavities. Typical improvement STC 5-6 in walls.

Installation and Maintenance Summary

Autex Insulation recommends that all thermal and acoustic insulation be installed in accordance with the manufacturers instructions (included in each bale of GreenStuf) and NZS 4246 Energy Efficiency - Installing Insulation in Residential Buildings.

Green Star NZ Credit Approval
Please note the information below provides an indication of 'potential points' under Green Star Office Design V.1. Green Star NZ points are weighted by the environmental significance of the category they are in. Each point contributes to the total overall score of the project but are not absolute. For further understanding of the Green Star rating tools, Greenbuild strongly recommends that users attend an 'Introduction to Green Star' seminar. More information is available at the New Zealand Green Building Council website.
Greenbuild has reviewed this product and confirms its potential contribution to points under the following credit categories:
Mat-11	One point is awarded where it can be demonstrated that 90% or more of the thermal insulation used are independently certified as having lower environmental impact than thermal insulation, as verified through a materials certification body recognised by the NZGBC (e.g., NZ Environmental Choice).
