Terracotta wall panels can give an exterior depth, rhythm and fired-clay character, but no material is automatically the “best solution.” The right outcome starts with a clear architectural brief and a coordinated wall system. Product geometry, supports, control layers, interfaces, current evidence, manufacturing and site responsibilities must all fit the building and procurement route.
Define what the exterior expression must achieve
Describe the intended character in practical terms: module, joint rhythm, depth, colour family, texture, gloss, variation, shadow and key viewing distances. Identify facade zones, entrances, corners, openings, parapets, bases and transitions. State which effects are essential and which may change during technical coordination.
Separate visual goals from measurable functions. A panel arrangement may influence shading or rain exposure, but solar, thermal, acoustic and water outcomes belong to a defined design and assembly. Record building use, climate, height, orientation, substrate, maintenance access, design actions, fire route and performance criteria before selecting the product.
Choose a module that works across the whole elevation
Test nominal width and height against structural grid, windows, doors, movement joints and dimensional tolerances. Map full units, cuts and specials. A clean typical bay can hide inefficient strips or numerous custom pieces at corners and openings, increasing tooling, handling and replacement complexity.
Request current feasible dimensions, section, orientation, mass, finish and fabrication for the proposed family. Review yield, support spacing, panel handling and replacement route together. Larger units may reduce joint length yet increase individual weight, bow sensitivity and consequences of damage. Freeze the module only after architectural, manufacturing and engineering reviews align.
Divide the elevation into rational product zones and create a coded unit schedule. Distinguish standard panels, edge pieces, corners, parapet units, base units and pieces around openings. This supports accurate quantity take-off, inspection, packing, installation sequence and future replacement without turning every position into a custom item.
Build the complete wall, not a panel-only detail
| Layer or interface | Decision to close | Named responsibility |
|---|---|---|
| Clay panel and clips | Geometry, engagement, restraint, movement and replacement | Product and system designer |
| Rails, brackets and anchors | Load path, adjustment, corrosion compatibility and substrate | Facade engineer and specialist |
| Cavity and control layers | Drainage, ventilation, air, vapour, thermal and fire continuity | Architect and enclosure/fire teams |
| Openings and transitions | Flashings, closures, movement, tolerances and trade sequence | Coordinating designer and contractor |
The current WBDG enclosure framework emphasizes strength, heat, air, moisture, durability, fire and continuity. Use it to test the build-up at boundaries, not as a generic approval. Project jurisdiction, exposure and professional design determine the actual requirements.
Coordinate attachments, movement and buildability
Trace self-weight and project actions through the panel, clip, rail, bracket, anchor and supporting construction. Calculations and tests should represent panel size, section, support spacing, orientation and proposed system. Address adjustment, tolerances, thermal and structural movement, vibration, corrosion isolation and fragment risk where relevant.
Survey the substrate before release. Draw rail joints, bracket locations, anchors, cavity depth, fire barriers and interfaces at large scale. Use an attachment trial and representative bay to check access, setting-out, replacement and trade sequence. Details that rely on ideal construction can fail when site tolerances meet inflexible components.
Control colour and finish from sample to production
Specify how appearance is made—body colour, firing, engobe, glaze, tooling, grooves or another documented treatment. Approve palette samples, then full-size panels, then a representative bay. Define a bounded colour and texture range rather than one perfect piece, and distinguish visual acceptance from dimensional or technical approval.
Retain labelled control samples at the factory and site with product code, finish, date and status. Agree production inspection frequency, viewing conditions and disposition of nonconforming units. Record approved changes. A digital rendering or small chip cannot show full-panel bow, joint shadow, directional texture or repeated variation.
Require current technical and environmental evidence
Product identity
Confirm family, section, dimensions, finish, mass, factory, date and the exact item represented by each report.
System evidence
Match engineering, testing and interface review to the proposed supports, wall build-up and project conditions.
Environmental scope
Check declared unit, modules, plant, geography, validity, verification and scenarios where reporting is required.
Exceptions
List gaps, assumptions, deviations and documents still due rather than treating silence as compliance.
The current ISO 14025:2026 sets requirements for environmental declaration programmes. An EPD reports defined information; it does not prove a product is universally preferable. Energy, recycling, waste-content and pollution claims need current product, factory, system boundary and reporting-period evidence.
Release procurement with scope and handover clarity
Close the product schedule, drawings, calculations, reports, samples, representative bay, quality plan, quantities, overage, unit codes, production slot, packing sequence, delivery, storage and installation method. Compare landed scope, not panel price alone. Identify engineering, supports, anchors, tests, freight, access, breakage and site services included or excluded.
Handover should include approved as-builts, inspection records, cleaning methods, access requirements, spares and a panel-replacement procedure. Agree who stores extra units and how their codes relate to the elevation. A maintainable facade is a planned owner outcome, not an inherent promise attached to the clay.
