Developed with designers, builders, BCAs and manufacturers in mind, the document enables users to assess the expected thermal performance of various forms of light steel framing construction.

The House Insulation Guide comes as a result of significant research by Redco NZ's Graham Rundle, who authored the work on behalf of NASH.  It provides good/better/best methodologies to meet the requirements of clauses H1: Energy Efficiency and E3: Internal Moisture of the New Zealand Building Code, as well as comprehensive information on the thermal break requirements for different roof and wall types. The document is supported by detail drawings, graphs and data tables, allowing users to readily determine whether specific light steel-framed constructions will satisfy New Zealand Building Code provisions.

Launched at the NASH conference last month, the House Insulation Guide coincides with the BRANZ Steel Building Basics Book and New Zealand Steel's recently released AXXIS video tip on thermal breaks.

The House Insulation Guide is available for free download from the NASH website.
