Terracotta / Ceramic Facade Panel
Technical product reference for terracotta and ceramic rainscreen facade panels — fired-clay, inherently non-combustible, UV-stable and colour-stable cladding for NCC 2022 compliant facade remediation. Products include Shildan, NBK Terreal, and Laminam large-format ceramic panels used in open-joint and closed-joint rainscreen configurations.
What are terracotta and ceramic facade panels?
Terracotta and ceramic facade panels represent the premium tier of non-combustible rainscreen cladding — fully inorganic materials that are inherently Group 1 under NCC 2022 and require no maintenance over a design life exceeding 50 years. They are the preferred replacement for ACP on high-rise residential where long-term performance, aesthetics, and fire compliance must all be satisfied simultaneously.

System Description
Moeding Alphaton terracotta panels are extruded from natural clay and fired at high temperature, producing a fully inorganic, non-combustible product classified Group 1 under NCC 2022. The open back-ventilated rainscreen configuration uses aluminium horizontal rails to carry slip-fit terracotta laths, allowing thermal movement without sealants. The material is inherently UV-stable, frost-resistant, and requires no painting or sealing over a 50+ year service life — ideal for high-rise remediation where future maintenance access is constrained.
Technical Properties
- Group 1 non-combustible — AS 1530.1
- Panel thickness: 25–40 mm extruded
- Panel width: 300–600 mm standard lath
Limitations
- Higher unit cost than FC or HPL systems
- Specialist installer required — slip-fit rail system
- Limited colour range (natural clay tones)
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Description
Shildan Argeton is a German-engineered extruded terracotta cladding system with a comprehensive Australian distribution network. Panels clip onto horizontal aluminium rails with no visible fixings — the slip-fit joint allows individual panel removal for maintenance or replacement without disturbing adjacent units. The system has been tested to Australian wind pressure requirements and fire tested to AS 1530.1 Group 1. Available in a range of Australian-specific colours and textures, with technical support from Shildan for facade engineering.
Technical Properties
- Group 1 non-combustible — AS 1530.1
- Panel thickness: 25–30 mm
- Lath widths: 225, 300, 450 mm
Limitations
- Specialist installer required — Shildan trained
- Lead times: 12–20 weeks ex-Germany
- Limited to horizontal lath configuration
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Description
Steni Colour panels are manufactured from glass fibre reinforced polyester (GRP) with a mineralised surface, classified non-combustible Group 1 under NCC 2022. The panels offer essentially unlimited colour specification including custom RAL matching, making them suitable for facade remediation where colour-matching to existing building elements is critical. The mineral surface is UV-stable, salt-resistant, and self-cleaning in rain. Installed on a concealed secret-fix rail system, Steni panels are lightweight (8–10 kg/m²) — significantly reducing structural loads compared to terracotta or porcelain alternatives.
Technical Properties
- Group 1 non-combustible
- Panel thickness: 8–10 mm
- Panel width: up to 1,200 mm
Limitations
- Not a traditional ceramic — specify correctly for heritage projects
- GRP substrate (not clay) — aesthetically different from terracotta
- Specialist importer — longer lead times in Australia
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Description
Laminam sintered stone panels are manufactured from natural minerals fired at extreme temperature to produce a dense, non-porous ceramic slab with zero water absorption. At 3–12 mm thickness with panels up to 3.6 × 1.6 m, Laminam offers the largest ceramic format available in Australia — reducing joint lines and delivering a monolithic facade appearance. The surface replicates stone, concrete, or metal aesthetics at lower weight than natural stone. Suitable for back-ventilated rainscreen facades with concealed mechanical fixings; the fired ceramic surface requires no sealing, coating, or maintenance.
Technical Properties
- Group 1 non-combustible — AS 1530.1
- Panel thickness: 3, 5.6, 12 mm
- Max panel: 3,600 × 1,600 mm
Limitations
- Brittle — specialist handling and cutting required on site
- Large panels require engineered mechanical fixing system
- Specialist importer — Laminam AU — lead times 10–16 weeks
PROCUREMENT SOURCES

Do not confuse terracotta / ceramic facade panels with:
- Terracotta roof tiles — fired clay roof tiles designed for pitched roof installation with mortar bedding or mechanical fixing systems; not the same product as a rainscreen facade panel with a back-ventilated clip or groove-and-slip fixing system
- Ceramic floor tiles — standard rectified tiles for horizontal floor loading; not rated for external vertical facade rainscreen applications, wind suction loads, or thermal cycling in an open-joint system
- Unglazed terracotta pavers — heavy-duty floor pavers; different density, thickness, and fixing system from facade cladding panels — not suitable for vertical rainscreen installation
- Brick veneer / face brick — a masonry construction system bonded to the structure with ties; terracotta facade panels are a rainscreen cladding product fixed to a subframe with clips — completely different structural system and specification
Disclaimer
Information is general only. Terracotta and ceramic panel cladding requires facade engineering including subframe design, thermal movement, and clip fixing specification. Engage a facade engineer before specification. Panel self-weight requires structural assessment of supporting framing.
