This Microsoft Excel (.xlxs) 25MB download of BRANZ House Insulation Guide 6th edition is for PC users.

Updates:

• A new 'Summary' sheet has been added to the tool
• An error has been repaired where the R-value for plain slab floors was higher than it should have been when adding floor topper insulation
• Improvements to the 'Correction for reduced perimeter insulation' section of the 'Roof spaces' sheet

The guide is now in two parts:

• The tables of construction R-values for common construction options for compliance under H1/AS1 and H1/VM1 5th edition
• The accompanying House Insulation Guide text [PDF] for guidance on insulation to meet or exceed H1 AS/1 and H1/VM1 5th edition.

This BRANZ webinar, in partnership with the Window and Glass Association of New Zealand (WGANZ), brings together experts from BRANZ, WGANZ and MBIE to explain the compliance requirements in H1/AS1 5th edition amendment 1.
