WRS82301 Lightweight Fireproof Brick: Archive Guide clarifies a LOPO page published in 2013. The old title described a light-weight terracotta fireproof clay brick, while the record listed a slender brick family. Lightweight and fireproof are historical marketing terms only. They do not establish current unit mass, assembly weight, reaction-to-fire classification, fire resistance or suitability for a particular building.
Read the 2013 WRS82301 record
The archive identified WRS82301 and listed a 240 × 60 × 11 mm field brick with two corner formats. It also carried full-body wording, about 4% water absorption, generic functions, uses, packing, 20-foot-container capacity, minimum order, sample timing and order lead-time fields. These details are not a current data sheet or quotation.
| Archive item | WRS82301 |
|---|---|
| Archived field format | 240 × 60 × 11 mm |
| Archived corner formats | (174 + 50) × 60 × 11 mm or (60 + 60) × 240 × 11 mm |
| Archived material field | Full-body wording; about 4% absorption |
| Archived title terms | Light weight and fireproof; current mass and fire evidence unverified |
The page’s only original image remains for recognition. It is not a current sample, mass record, fire-test specimen or evidence of production.
Limit the lightweight description
The old page does not provide a dependable current unit mass, area basis, comparison product or assembly definition. A nominal 11 mm thickness does not prove low weight, easier handling or reduced demand on a building. Product mass and complete wall mass are also different scopes.
Ask for current dimensions, tolerances and mass data for the exact candidate, with a clear measurement basis. Qualified project professionals should evaluate the product within the actual wall proposal. Do not turn the legacy adjective into a comparative claim, and do not infer structural implications from the archived format.
Keep fireproof wording historical
“Fireproof” gives no test method, specimen, classification, assembly, orientation, date, market or field of application. It cannot support a current fire strategy. The old heat-resistant and firebrick function terms are likewise insufficient to establish fire behaviour or a maximum service temperature.
If fire performance matters, the project team should define the applicable requirement and review dated evidence for the exact current product or assembly. Product-level information must not be represented as whole-wall evidence. A title, photograph, code or nominal thickness can never substitute for an applicable fire classification or assessment.
Use archived formats as tracing clues
The narrow field format can guide early course and orientation studies. The two corner notations may identify former return units, but they do not confirm present geometry, tolerance, compatibility, colour matching or availability. Request dated drawings and labelled samples for every current field and corner piece.
Qualified professionals must coordinate project-specific substrate, movement, moisture and interfaces using confirmed system information. This archive provides no generic loads, spans, support spacing, anchors or installation instructions. If a successor differs from WRS82301, update elevations, quantities, samples, approvals and commercial records together.
Apply the complete archive boundary
Archive boundary: WRS82301, full-body material wording, all field and corner dimensions, about 4% absorption, acid, heat, non-slip, wear and firebrick functions, uses, packing, 20-foot-container capacity, MOQ, samples and order lead time belong only to 2013.
Request current reports and declarations that identify the exact product, specimen, method, result, scope and market. Reconfirm colour, surface, formats, corners, mass basis, quantity, packaging, minimum order, sample status, production window, delivery and payment in writing. Keep all samples, drawings, evidence and quotation linked to the same candidate.
Separate appearance approval, product mass review, fire review and commercial acceptance in the decision register. Each has different evidence and responsible reviewers. Superseded samples or documents should remain clearly marked so they cannot overwrite the approved current proposal.

Request a current WRS82301 review
Share the project location, wall area, elevations, desired appearance, corner conditions, required mass information, fire requirement if applicable, approximate quantity and programme. Cite WRS82301 and the archived formats so LOPO can trace the former family.
Email roger@lopoterracotta.com or use the contact form. Request current identification, labelled samples, dated drawings, applicable evidence and project-specific commercial information.
Before selection, verify that sample codes match every drawing, report and quotation. Record open questions in a dated log and update it when product identity, mass basis, fire-document scope or supply status changes. This retains the archive’s tracing value without presenting light weight or fireproof as current facts.
For appearance review, classify every piece as inspiration, a representative range sample or a proposed production benchmark. Note viewing light, distance, adjacent finishes and date. Record whether colour or texture variation is expected, and keep the approved set connected to the exact current product and drawing. If LOPO proposes a successor, retire WRS82301 from active schedules while retaining it in the archive cross-reference.
For evidence review, create separate fields for unit mass, measurement basis, product fire documents, complete-wall documents and reviewer status. Record the issuer, date and scope rather than simply marking a claim approved. When the product, requirement or document changes, update elevations, quantities, approvals and commercial records together. Recheck this register before technical acceptance and purchase so decisions do not combine an archived adjective, a sample from one brick and reports for another.
