Notes
Non-load-bearing decorative elements fixed to a prepared substrate.
B1 — mouldings are not relied on for structural support; fixings and adhesive transfer moulding dead load to the substrate. Relevant B1.3.3 conditions: (a) self-weight, (c) temperature (control joints accommodate differential expansion), (f) earthquake, (h) wind, (j) impact. Substrate design and fixing schedule remain the designer's/engineer's responsibility.
B2 — not less than 15 years under B2.3.1(b), consistent with the plaster cladding system the mouldings are integrated into; conditional on the BPIR maintenance programme.
F2 — no asbestos; CFC-free EPS; cement-based components are alkaline irritants in wet/powder state only (refer SDS).
E2 — NOT a weathertight cladding and no part of the weathertight line. The substrate must be independently weathertight before fixing; E2 compliance rests with the underlying cladding system and the designer.
C — no Group Number held or claimed for the EPS-cored systems.
Evidence
The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:
Compliance is demonstrated by the material standard for the EPS core, the installation methodology in Accumen's controlling documents, and the maintenance regime required to sustain performance.
CITED STANDARDS
AS 1366.3 Rigid cellular plastics for thermal insulation - rigid cellular polystyrene, moulded. EPS core is kiln-dried S-grade: nominal density 16 kg/m3; compressive stress at 10% deformation min. 85 kPa; cross-breaking strength min. 165 kPa. (B1)
AS 2498.3 Methods of testing rigid cellular plastics - compressive stress at 10% deformation.

Design requirements
Substrate: specify a substrate that is independently weathertight before the mouldings are fixed - typically a direct-fix or cavity-based plaster cladding system, masonry, ETICS or prepared brick veneer. Surface must be flat to within 3 mm and compatible with the adhesive.
System selection: DecraShape for standard profiles and volume work; fourPLUS where impact resistance or heritage replication is required; tenPLUS for portico build-ups and large projecting profiles; ShapeCrete at ground level, for impact-prone details and where a solid stone-like finish is required.
Detailing: control joints at 1.2-5.4 m must align with control joints in the underlying structure. Fixing centers 0.8-1.6 m. Battens and angle supports, where required by exposure or profile, are installed by the builder before fixing. Specify paint LRV per the cladding system - dark colours accelerate movement and degradation.
Confirm maximum profile size, weight and length with Accumen at design stage.
Installation requirements
Install only by competent tradespersons per the Accumen Installation Manual.
Preparation: substrate must be flat to within 3 mm, clean, dry and independently weathertight before fixing. Where required by exposure or profile, the builder installs the batten or angle support first.
Fixing: apply TidyUp adhesive plaster to the back of the moulding with a notched trowel at 3-5 mm. Mechanical fixings - stainless steel recommended; use a large washer, set below the surface and plastered over. Fixing centers 0.8-1.6 m per profile size and weight. ShapeCrete capitals must be fixed through the capital into the center post or soffit.
Joints: control joints between lengths at 1.2-5.4 m, aligned to control joints in the structure, using MS Polymer sealant with backing rod.
Cutting: concrete handsaw or mitre saw with masonry blade. Eye protection, dust mask and scaffolding required.
Finishing: fill gaps to the wall with MS Polymer sealant, then paint per the cladding system within LRV limits.
Maintenance requirements
Durability of not less than 15 years (B2.3.1(b)) is conditional on the following programme, from the Accumen Maintenance Guide.
Annual inspection (12 months): inspect joints, sealant, flashings and the moulding surface for damage and potential water ingress. Inspect the paint and repair paint-film damage promptly to maintain weathertightness. Engage a registered plasterer to remedy physical damage.
Cleaning (12-18 months): remove loose dirt and dust; wash with diluted house-washing liquid using a soft broom and rinse with clean water. Do NOT use strong solvent cleaners or harsh water-blasting. Avoid run-off into stormwater.
Repainting (7-10 years): repaint on the same cycle as the surrounding plaster cladding, by a professional painter. Darker colours (low LRV) may need earlier repainting. Paint LRV must comply with the cladding system specification.
The coating is integral: mouldings must remain painted or recoated in a purpose-designed plaster system at all times.
