Terracotta panel installation succeeds when survey data, engineered supports, interfaces, panel tolerances and inspection records all follow the same approved design. The work is best managed as a sequence of hold points, with each concealed layer checked before the next layer closes it.
1. Close the design and submittals first
Before site work, align architectural elevations, structural calculations, panel schedule, support drawings and interface details. Confirm design loads, substrates, anchors, bracket adjustment, rail spans, panel orientation, joint widths, cavity depth, drainage, ventilation, insulation and membrane continuity. Mark who designs and supplies each component; gaps between the panel package and backing-wall trades are a common source of late changes.
Review representative panels, colour range and critical details in a project mock-up. Include a corner, opening, base, top, fire barrier and a panel replacement where possible. Record the accepted appearance and build sequence. Inspection and test plans should identify hold points, tolerances, sample frequency, responsible parties and the documents required for release.
2. Survey and set out from agreed datums
Verify the handed-over grid and elevation datums against the actual structure. Survey slab edges, wall faces, openings, embeds and known interface zones; do not assume the substrate follows the design model. Plot deviations and confirm that bracket adjustment can absorb them without reducing edge distances, rail capacity, cavity clearances or panel engagement.
Transfer approved control lines to the work face and mark bracket and rail positions from coordinated shop drawings. Establish independent checks for vertical and horizontal control so error does not accumulate across floors. Protect datums throughout construction and recheck them after access systems or adjacent trades disturb the work area.
3. Install brackets and primary rails
Inspect substrate condition and confirm anchor locations before drilling or fixing. Each bracket must use the specified anchor, embedment, isolation material and adjustment method. Welding is suitable only where the engineered detail, materials, qualified procedure and site controls require it; many systems use bolted brackets. Repair damaged protective coatings by the approved method and keep records for concealed fixings.
Install primary rails in the approved sequence, maintaining verticality, plane and movement provisions. Do not lock adjustment points prematurely. Survey a representative area, then tighten or secure connections to the specified procedure. Check that dissimilar metals are isolated where required and that rail ends, splices and brackets do not obstruct cavity drainage.
4. Coordinate transoms and cavity layers
Set secondary rails or transoms to the panel module and approved clip geometry. Verify spacing, level, connection capacity and required clearances at splices. A small support error can appear later as stepped joints or incomplete clip engagement, so check the first bays before repeating the work across the elevation.
Install membranes, insulation, cavity barriers, flashings and fire stopping to their respective approved systems. Maintain continuity at brackets, slab edges, windows and service penetrations. Fire-resistant sealant and mineral wool are not interchangeable generic products: backing, compression, orientation, substrate and fixing must match the tested or assessed detail.
5. Install panels to the approved sequence
Check panel codes, dimensions, colour distribution and visible defects as crates are opened. Protect edges and keep units off contaminated surfaces. Start from the project’s established control point and use only the specified clips, pads, gaskets and restraints. The archived page mentioned at least two fasteners per panel and bottom-to-top installation; neither statement should override the engineered system layout.
At regular intervals, measure joint width, course level, elevation plane and clip engagement. Confirm required movement clearances and avoid forcing a brittle panel into position. Separate fixed and sliding points exactly as detailed. Corners, cut panels and top closures deserve specific checks because access and engagement can differ from typical field panels.
6. Clean, protect and replace correctly
Agree a cleaning trial on spare material before treating the elevation. Use the current manufacturer guidance for water quality, pressure, tools and cleaning agents; the old page’s high-pressure-water instruction is not appropriate for every surface or joint. Prevent runoff from staining adjacent work, and never use an unapproved acid, solvent or abrasive process.
Protect completed areas from impact, grinding dust, sealants and scaffold ties. If a panel is damaged, follow the documented removal and replacement sequence rather than levering against neighbouring clay edges. Recheck engagement and joints after replacement.
7. Build QA into handover
Installation records
Keep survey reports, anchor and connection checks, torque or weld records where applicable, photographs, nonconformance reports and approvals.
