9.1 GENERAL
This Section provides specific requirements for insulation that incorporates an IR reflective metallic surface in the form of either a rolled metallic foil or a metallic deposit. Sections 1 to 3 apply in addition to this Section. In addition, insulation materials or assemblies that include bulk insulation components shall conform with the requirements of Sections 4 to 8, as applicable.
9.2 PRODUCT GROUPS
IR reflective insulation falls into one of the following product groups:
(a) Group 1 Pliable building membranes that have at least one IR reflective surface. If the products within this group are installed facing an appropriate airspace, they can provide thermal insulation.
NOTE: These products are often intended to have a prime function as a sarking or vapour control membrane. For this application, test methods, performance classifications and installation requirements are covered by AS/NZS 4200.1 and AS 4200.2.
(b) Group 2 Single sheet segmented IR reflective pliable membranes for installation between structural members (e.g. folded single sheet foil laminate).
(c) Group 3 Multiple layers of segmented IR reflective pliable membranes formed and assembled to give multiple IR reflective airspaces for installation between and over structural members.
(d) Group 4 IR reflective material bonded directly or via a substrate to a rigid insulation or support to provide a product in sheet form for application to structural members.
(e) Group 5 IR reflective material bonded directly or via a substrate to a pliable non-IR reflective insulating material for installation between or over structural members or in a continuous length.
(f) Group 6 IR reflective material bonded directly or via a substrate to the inside of individual wall cladding sheets (metal or plastic), weatherboard type.
(g) Group 7 IR reflective material bonded directly, or via a substrate, to the underside of a metal roof or wall sheet.
9.3.2 Dry delamination
All products shall pass the requirements of AS/NZS 4201.1, with the following modifications:
(a) Group 3 Sample size, full product width; number of samples, 4.
(b) Group 7 Test temperature 90 2.5°C.
(c) Group 1 products shall be exempt from this requirement, provided they are in accordance with AS/NZS 4200.1.
