How to Achieve H1 Compliance with GreenStuf

Meeting compliance for the new H1 Energy Efficiency standards in commercial spaces requires access to quality insulation materials. The newest additions to the GreenStuf range are perfectly suited to helping you achieve this. These four new products have been designed to provide wall and ceiling thermal efficiency, helping to create healthier commercial spaces around New Zealand.

The new products include:

Thermal Wall Pads:

GreenStuf R3.2 140mm Pads
GreenStuf R3.6 140mm Pads

These wall products exceed the minimum H1 requirements for across climate zones 1 – 6.

Thermal Ceiling Insulation:

GreenStuf R3.4 140mm Roll
GreenStuf R3.6 140mm Blanket

A double layer of these ceiling products will achieve R-values compliant across all climate zones. When a single layer of these products is used in a suspended ceiling system, you are able to achieve compliance for zone 1 and 2.

Need some help with H1 compliance? The GreenStuf team can complete freeH1 Calculation reports for you while also being able to provide Masterspec writing support. Feel free to reach out and discuss your next project with their team.

The GreenStuf range is manufactured using a minimum of 50% previously recycled polyester fibre and is recyclable at the end of its life. Their view is that waste is a resource with potential, not something to be disposed of. With this in mind they operate a zero-waste production line; all product trimmings and offcuts are reused, and all waste material is reintegrated back into production.
