Certificate number: CM40365-I01-R01 This certificate is only valid when reproduced in its entirety. Page 6 of 8 Condensation Management To support compliance with NCC 2022 Volume Two – Performance Requirement H4P7 (Condensation and water vapour management), hygrothermal modelling has been undertaken in accordance with Verification Method H4V5, using AIRAH DA07 acceptance criteria (mould index not exceeding 3 over a 10-year assessment period). The assessment models DeltaCool EPS & TPC wall panels comprising 0.4 mm steel / 50 mm EPS-FR or TPC / 0.4 mm steel, for NCC Climate Zones 1–3. In all cases, for both insulation cores and in Climate Zones 1, 2 and 3, the acceptance criteria set forth in Section 6 of AIRAH DA07 (NCC 2022 Vol 1 - F8V1 Condensation management) has been met, where the mould index of 3 is not met or exceeded over 10 years under worst-case conditions. The steel exterior acts as a vapour barrier. Condensation risk would only occur if this barrier were deliberately penetrated, which falls outside the scope of this certification.

Material Group Numbers Group Numbers have been determined in accordance with testing conducted to ISO 9705 and assessment against AS 5637.1:2015. Construction requirements for Group 1 for the EPS-FR & TPC cores are shown below. EPS-FR Core Group 1: Panel thickness up to 250mm • Insulating sandwich panel, nominal thickness 250mm or less. • Panel core of Class SL (to AS 1366.3) expanded EPS. • Clad both sides with “Colorbond” steel, thickness 0.4mm or greater. • Panel to panel junctions require steel angles fixed to the steel skins at not more than 300mm centre, with steel rivets. Ceiling panel to panels joins require steel (stitch) rivet connecting the metal skins at not more than 1200mm centres. Smoke Growth Rate Index SMOGRARC < 100 m2/s2. TPC Core Group 1: Panel thickness 100mm only. • The interlocking joints to be filled with a fire-resistant sealant secured with 4.8 x 12mm 304 grade stainless steel rivets at 1200mm centres. • The internal mitred corners in the walls and the stepped wall to ceiling junctions to be filled with a fire-resistant sealant and covered with 40 x 40 x 1.2mm pre-painted steel angle secured with 4.8 x 12mm 304 grade stainless steel rivets at 200mm centres. • Panel comprising 0.6mm steel skins with a 100mm thick Phenolic composite (TPC) core. Smoke Growth Rate Index SMOGRARC < 100 m2/s2. Source: BRANZ, Report FAR2489 – Issue 3 dated 23/02/2023 & BRANZ, Report FI6323-01-2 dated 25/05/2023.
