Answer

I consider that specifically providing for Structural Insulated Panel systems (SIPs) with a CodeMark certificate in Schedule 1A of the Building Act 2004 does not present any substantial additional risk to those under the current requirements. A CodeMark certificate provides independent assurance that a building product or method meets the building code.
