F501876 is an archived LOPO reference for a red terracotta window plate intended to bring fired-clay character into an exterior window zone. The legacy record is useful as a design starting point, not as a current technical submittal. It identifies a nominal format and colour while leaving the project-specific profile, interfaces and present production status to be confirmed. This updated guide explains what the reference can communicate to architects and what must be checked before it enters a specification.
F501876 archive snapshot
The original listing described a natural-clay, red component associated with window detailing. It recorded a 300 × 600 × 18 mm size and said customised design was available. Those entries are historical catalogue data; they do not establish today’s tolerances, composition, finish, availability or suitability for a particular facade.

The retained photograph belongs to the historical page. Use it as a general visual reference only; a current sample and drawing should define the proposed F501876-derived component.
Why a window zone benefits from a shaped response
Windows interrupt the field of a facade. Their heads, jambs and sills bring ceramic surfaces into contact with frames, membranes, flashings and neighbouring cladding. A purpose-developed window plate can help carry the facade’s colour and module toward that opening, giving the elevation a more resolved edge than a generic cut piece might provide. The value is primarily architectural: continuity, shadow control and a deliberate transition between clay and glass.
“Window plate” is the wording preserved in the archive, but the exact intended location is not defined there. Project teams should identify the desired edge condition and use current coordinated drawings to establish what the term means for their building.
Red clay character around glass and metal
Red terracotta can create a warm frame against clear glass, dark mullions, pale stone or concrete. Its effect changes with daylight: direct sun strengthens the colour, while reveals and recessed edges deepen it. The 300 × 600 mm archived face proportion suggests an orderly rectangular rhythm, yet that record should not be treated as a promise that the same format is currently offered.
Colour decisions should be made with physical samples viewed beside the specified glazing and frame finish. Fired clay naturally reads through tone, surface and edge detail together. A project-approved sample establishes the intended range more reliably than a screen image or an old catalogue description.
What the old listing does—and does not—verify
The historical page also carried broad claims about facade performance, certifications, product ranges, delivery terms and factory capacity. Those generic statements are not repeated here as current facts. They may have referred to other panel families, earlier test configurations or documents that have since changed. F501876 should therefore be evaluated through current, model-specific information rather than inherited claims.
Ask the LOPO team which declarations, reports and certificates are presently applicable to the proposed product and destination market. Confirm the exact material description, geometry, colour range, surface, dimensional tolerances and edge quality. Performance evidence should match the proposed component and its intended use. The project facade consultant and system engineer remain responsible for the complete wall design and its interfaces.
A careful route from reference to specification
Begin with the architectural intent: mark the window locations, identify the visible faces, and provide elevations, sections and reference imagery. State whether the red element is meant to blend with a larger terracotta field or act as a contrasting frame. LOPO can then advise whether F501876 remains relevant, whether a current standard product is closer, or whether a revised custom profile needs development.
Before procurement, align the drawing revision, sample approval and written product description. Review representative colour and texture under project lighting, and coordinate the component with the selected facade system through the responsible design team. Packaging, quantity, programme, current commercial terms and applicable documents should all appear in the quotation or submittal rather than being copied from this archived page.

These resources provide context, but no precedent automatically validates F501876 for a new building. Each project requires its own current review.
Discuss a current red window-plate requirement
To assess a red terracotta window plate for your project, send the building location, application, drawings, visible dimensions, preferred red tone, surface direction, approximate quantity and delivery schedule. Mention archive item F501876 so the team can trace the reference, then ask for current drawings, samples, production confirmation and applicable documentation.
Email roger@lopoterracotta.com or contact LOPO Terracotta. A concise design brief will help the team respond with a relevant present-day option instead of relying on the legacy page.
An enquiry should also distinguish appearance goals from required evidence. A reference photograph can explain the desired tone and shadow, while the written brief should identify the governing project standards and approval route. If the component must coordinate with other terracotta panels, include their approved sample codes and current drawings. This gives colour, profile and documentation reviews a shared basis. Do not assume that an archived panel result transfers to a shaped window element; ask for information tied to the exact proposed configuration and production batch.
