Terracotta panel curtain wall applications cannot be selected from appearance alone. “Curtain wall” is used differently across markets and contracts: it may describe a complete non-loadbearing exterior wall, an opaque rainscreen in front of a backing wall, a secondary skin, or simply the visible cladding. Define the assembly and responsibility boundary before choosing panels, supports or evidence.
Define what “curtain wall” means on this project
Write a one-sentence system definition and illustrate it with a wall section. State whether terracotta is the outer screen, an infill within a framed wall, a freestanding screen, a louver field, an interior finish or part of a double-skin composition. Identify which construction provides air, water, thermal and fire control.
Use the terminology of the governing code and contract, not a supplier headline. A terracotta rainscreen may be non-loadbearing yet still sit outside a separate backing wall. A glazed curtain wall with terracotta elements has different drainage, movement and trade interfaces. If the term remains ambiguous, bids will include different scopes and cannot be compared fairly.
Match the application route to its real function
| Application route | Primary design role | Key questions before selection |
|---|---|---|
| Opaque ventilated rainscreen | Weathering screen and architectural finish outside a drained cavity | What is the backing wall, load path, cavity strategy and joint arrangement? |
| Terracotta on a glazed wall | External shading, pattern, depth or privacy in front of glass | Who designs attachments, glass interfaces, access, movement and replacement? |
| Baguette or louver screen | Linear composition with project-defined view, shade or screening objectives | What orientation, spacing, support, safety and performance evidence are required? |
| Interior wall application | Durable visual finish or screen within conditioned space | What substrate, impact, fire, acoustic, cleaning and occupant-safety criteria apply? |
Do not transfer a fixing detail or test result from one route to another. Orientation, exposure, access and consequence of failure change the design basis. Confirm that the proposed product is intended for the exact use and that its installation method is accepted by the relevant design professionals and authority.
Map use zones instead of specifying one typical panel
Divide elevations by height, wind zone, corner and edge exposure, seismic demand where applicable, impact risk, access and unusual orientation. Identify entrances, bases, parapets, soffits, screens, plant areas, set-backs and transitions to other materials. A field panel and a suspended soffit unit may look related while requiring different retention and inspection.
Give each zone a code tied to panel types, supports, design actions and evidence. Record whether the design permits site cutting, special shapes or handed units. Zone schedules make quantities clearer, expose exceptional pieces early and prevent a generic detail from being repeated where it does not apply.
Write performance criteria for the complete assembly
Structure
Self-weight, wind, seismic action, impact, building movement, panel engagement, subframe and substrate.
Moisture
Rain shedding, cavity drainage, flashings, openings, penetrations and continuity of the water-control layer.
Fire and heat
Material and assembly requirements, cavity barriers, insulation interfaces and thermal-bridge review.
Use and upkeep
Appearance range, safe access, cleaning, inspection, individual replacement and spare-unit strategy.
State the jurisdiction, standard editions, design actions and acceptance criteria. Require calculations and complete reports for the actual panel profile, span, orientation and support. The current WBDG enclosure principles emphasize coordinated control functions and interfaces; a product attribute cannot substitute for whole-wall design.
Coordinate every edge and interface
Draw the base, parapet, corners, window heads, jambs and sills, expansion joints, soffits, penetrations and transitions to glazing or another cladding. Trace drainage and movement through each detail. Confirm substrate tolerances, bracket adjustment and installation sequence with the responsible trades.
Where terracotta sits in front of glass, study reflected heat, cleaning access, bird and debris risks, replacement paths and how supports appear from inside. For interior applications, address touch, impact, protrusions, air quality documentation where required, and compatibility with partitions or backing construction. The application determines the questions.
Assign scope and evidence before tender
Issue a matrix for panels, special shapes, clips, rails, brackets, anchors, secondary steel, membranes, insulation, cavity barriers, flashings, sealants, calculations, tests, mock-ups, access, installation and spares. For each item, name the designer, supplier, installer, reviewer and approval route. “By others” should identify the actual package and required information exchange.
Hold coordinated reviews at concept and pre-tender with the architect, enclosure specialist, structural engineer, fire adviser, services team and installer input. Record unresolved interfaces, their owners and due dates before they become assumptions in supplier prices.
Require bidders to respond to the same panel schedule and evidence register. Price exclusions, qualifications and project tests before award. Before production, approve current product data, colour-range samples, calculations, reports, shop drawings and a representative mock-up. At handover, retain as-builts, product codes, inspections, maintenance guidance and replacement stock.
Close the 2014 claims and select by current evidence
The archived page dated 10 September 2014 described exterior, composite and interior “curtain wall” uses while making broad environmental, acoustic, comfort, energy and market-adoption claims. Those statements did not define assemblies or supporting reports. They are historical marketing context, not current performance or demand evidence.
Start with current terracotta rainscreen information, review linear options on the terracotta baguette page, and compare relevant work in the project gallery. Then request product and system documents for the chosen application.
