An architectural terracotta project starts with a product and system brief—not with a generic promise that every fired-clay panel performs the same way.
This guide replaces a 2019 “terracotta panels age” promotion with a practical decision map. It separates panels, baguettes and other openwork units; defines the complete facade layers and responsibilities; and identifies the samples, calculations, tests and handover records needed before a project is released.
Identify the architectural terracotta unit first
“Terracotta panel” is often used broadly, but the design route changes with unit shape, mass, cavity, edge, orientation and intended use. A flat or shaped rainscreen panel, a hollow baguette, a perforated screen and an interior facing do not share one load path or one set of details. Record the exact manufacturer, item, body, surface, work size, tolerance, mass and declared application before comparing options.
Rainscreen panel
An outer cladding unit attached to a project-designed support/enclosure assembly. Confirm orientation, rear profile, edge zones, rails/clips and replacement route.
Baguette or louver
A linear or shaped unit used for screening, visual rhythm or shading concepts. Its spans, end conditions, supports and falling-object safeguards are project-specific.
Openwork or screen unit
Open patterns affect views, airflow, rain entry and access but do not prove ventilation, shading or weather performance without geometry and analysis.
Interior facing
Interior use changes substrate, impact, fire, cleaning and attachment questions. Exterior evidence cannot simply be transferred, and vice versa.
Turn the design intent into a controlled project brief
| Brief section | Define | Do not assume |
|---|---|---|
| Building and exposure | Use, height, location, elevations, orientation, environmental actions and access | A past photograph proves suitability for another climate or building |
| Product schedule | Item, body, profile, surface, colour range, work size, tolerances, mass and quantities | A web colour or generic family name is a specification |
| System route | Substrate, brackets/rails/clips/anchors, cavity, insulation, membranes and interfaces | The face unit alone is a complete curtain wall |
| Design actions | Self-weight, wind, seismic/impact where applicable, movement, tolerances and redundancy | “Lightweight,” “strong” or easy replacement establishes capacity |
| Evidence | Applicable standards, declarations, exact-product tests, calculations, mock-up and inspections | Marketing claims transfer across items, thicknesses or systems |
| Delivery and closeout | Packing, sequence, spares, replacement access, cleaning, maintenance and as-builts | Installation speed or recyclability is automatic |
Design the complete facade, not only its skin
The outer unit is one component in a load-bearing and weather-managing assembly. Assign responsibility for support brackets, rails, clips, anchors, backing wall, insulation, membranes, cavity, fire barriers, flashings, seals and interfaces. Coordinate gravity and lateral loads, substrate capacity, building movement, tolerances, corrosion compatibility and safe replacement with the responsible designers and engineers.
Open joints may be part of a drained and ventilated rainscreen concept, but they are not waterproofing. The project must establish rain entry, drainage, ventilation where designed, pressure moderation, membranes, openings, bases, parapets and transitions. Fire, thermal and acoustic performance also belongs to the complete assembly and building—not to an image of fired clay.
Control colour, surface, geometry and replacements with samples
Fired-clay colour and texture must be defined with representative physical samples, not screen images. Establish the accepted range, reference batch, viewing distance and light, distribution/mixing plan, joint colour and depth, orientation and special pieces. Retain signed control samples and a coded elevation schedule so procurement, installation and later replacement use the same reference.
Build a representative mock-up containing the actual unit, support route, joints, corners, openings, interfaces and workmanship. Agree acceptance criteria before the trial. A visual mock-up approves appearance and constructability only to its recorded scope; structural, fire, water, thermal, acoustic and durability claims require the relevant project evidence.
Release procurement and installation through documented gates
- approved product schedule, current availability, dimensions/tolerances, colour range, quantities and spares;
- coordinated elevations, corners, openings, terminations, movement joints and adjoining-material details;
- complete support/enclosure design, calculations, anchors, corrosion compatibility, water/fire interfaces and replacement access;
- applicable standards, authority requirements, exact-product/system test evidence and delegated-design boundaries;
- representative mock-up, control samples, installer competence, inspection/test plan and nonconformance process;
- packing, transport, storage, sequencing, protection, safe handling and building-access plan; and
- as-built drawings, product/batch records, inspections, cleaning instructions, maintenance plan and spare-stock log.
Change control matters after approval. Record any revised clay body, surface, dimensions, profile, manufacturer, support component, anchor, substrate or production batch; assess the affected calculations, tests, samples and interfaces before accepting substitution.
Use current product and evidence resources

Prepare an architectural terracotta project brief
Share the building and elevations, intended panel/baguette type, module and finish, substrate/support concept, interfaces, quantities, exposure, evidence requirements, standards, mock-up plan, programme and delivery constraints. Final selection, engineering, enclosure design, installation and compliance remain project-specific.
