An Industry First Solution to Help You Achieve H1 Compliance

The second round of changes being made to the H1 energy efficiency clause are coming this May. One of the areas of particular focus is the increase for ceilings in residential buildings to now achieve a minimum R-value of 6.6. This has led to the need for alternative insulation solutions to achieve H1 compliance.

To meet these new requirements, GreenStuf has introduced the use of a double-layer system. When using a double layer of GreenStuf Thermal Ceiling Insulation R3.4, you can achieve an insulation R-value of R6.8, hence allowing you to meet the minimum R6.6 required in ceilings. This performance has been appraised by BRANZ and makes GreenStuf the first BRANZ-appraised double-layer polyester insulation system in the New Zealand market. 

They rigorously test their products to ensure they can meet the demands of the New Zealand building codes and requirements of such varied climate zones. While there has been some concern about double-layer systems not achieving a double R-value, they can prove that this is not the case. Their BRANZ appraisal documents are a clear indicator of this, showing the robust testing that they have gone through to meet these high standards.
