A screen-block image can begin a design conversation, but it cannot identify a product or approve a wall. This page preserves seven references published by LOPO on 11 July 2023. The archive does not name their projects, designers, locations, dates, photographers, block manufacturers, materials, dimensions or construction systems.
Use the images as an unattributed external reference set. Turn the visual intent into a controlled brief for product identity, module and open area, pattern and orientation, edges and corners, support and restraint, guard/falling-object risk, fire and weather interfaces, maintenance, mock-ups and evidence. Do not call a visible perforated unit LOPO, terracotta or a Jali SKU without a traceable match.

Write the screen-block design brief before selecting a pattern
Start with the screen’s job, context and measurable acceptance criteria. A pattern that looks open in a photograph may behave differently after its depth, rotation, joints, framing, view angle and surrounding construction are defined.
| Field | Define before selection | Evidence/record | Do not infer from a photo |
|---|---|---|---|
| Purpose and location | Interior divider, sheltered screen, balcony/corridor edge, facade layer or freestanding feature; occupied sides, height, access and exposure. | Plans, elevations, sections, risk register and responsible designers. | Interior/exterior approval, privacy, ventilation, shading or guard function. |
| Exact product | Manufacturer, plant, family/code, current status, material/body, forming/firing/finish route, intended use and revision. | Controlled data sheet, drawings, labelled sample and quotation. | LOPO/Jali identity, terracotta/clay, colour name, SKU or current availability. |
| Module and open area | Block work size/depth, joint width, repeat module, gross panel dimensions, orientation and framed boundaries. | Dimensioned unit and panel drawings; declared/calculated open-area method and value. | Dimensions, scale, net free area, airflow or daylight from perspective pixels. |
| Pattern and views | Rotation, repeat, alignment, permitted variants, direct/oblique sightlines, privacy targets, sun/view direction and night lighting. | Pattern map, sun/view studies and full-size visual mock-up. | Universal privacy, glare control, passive cooling or a “glowing lantern” result. |
| Support and movement | Self-weight path, base/supports, lateral restraint, frame/ties/anchors, joints, tolerances, deflection and differential movement. | Named engineer’s calculations/drawings and verified component/assembly evidence. | Load-bearing capacity, permissible height/span or a mortar/adhesive-only solution. |
| Edges and interfaces | Corners, ends, heads, sills, bases, openings, parapets, movement joints, adjacent walls/glazing and replaceable access. | Large-scale details, prototypes, sequence and inspection hold points. | Cutability, corner pieces, concealed framing, edge strength or a clean termination. |
| Safety and guard | Occupant contact, climbing/openings, impact, falling pieces, overhead/escape-route exposure and whether a separate guard is required. | Project risk assessment, applicable code criteria and complete-system calculation/test. | Guard compliance, child safety, impact resistance or falling-object control. |
| Fire and weather | Fire strategy, joints/frame/anchors, cavity/interface continuity, rain entry, drainage, freeze/thaw/salts where relevant and corrosion compatibility. | Scoped product/assembly documents, fire/water details, exposure evidence and maintenance plan. | Fire separation, smoke control, waterproofing, weatherability or environmental benefit. |
Coordinate module, opening and boundary together
Gross module versus clear opening
Record unit size, depth and joint; solid/open face areas; any angled or tapered passage; and the framed panel. State whether “open area” is geometric face area, minimum throat or another defined method.
Effective airflow is separate
Open-area percentage alone does not establish air change, pressure drop, thermal comfort or cooling. Those depend on weather, openings, room/building flow paths and a project-specific analysis or test.
Daylight, shade and privacy differ
Set view/sun angles, times, seasons and observer positions. Depth and orientation can block one direction while remaining open in another; one attractive shadow photograph is not acceptance evidence.
Repeat and tolerances accumulate
Dimension full panels, not just a nominal block. Coordinate joints, frame zones, rotations, colour/pattern changes, cut avoidance, movement and accumulated dimensional variation.
Close every edge condition
Resolve corner, return, end, sill, head, base, opening and transition pieces. Confirm whether factory specials, whole units, cuts or cover profiles are used and how exposed edges are protected.
Approve a representative range
Use labelled current samples to define colour, surface, openings, edges, allowed marks and unacceptable extremes. A product chart or image search cannot approve production variation.
Treat the block, joints and supports as one screen system
A non-opaque unit is not a complete enclosure. The project team must define how units, joints, frames, ties/anchors, bases, heads and adjacent construction carry self-weight and lateral actions while accommodating tolerances and movement. Do not assume that the screen is load-bearing, self-supporting or suitable as a guard.
Structure and temporary state
Check panels during construction and service. Name responsibility for substrate/supports, frame, ties/anchors, joints, movement, erection sequence, temporary bracing, inspections and later replacement.
People and falling-object risk
Where occupants can lean, climb, strike or pass below, assess openings, impact, detachment and access. Provide a separate compliant guard where the screen itself has not been designed and evidenced for that duty.
Fire continuity
Openings may transmit flame, hot gases or smoke. Coordinate the block, joints, frame/anchors, cavity barriers, adjacent walls and penetrations with the project fire strategy; decorative screening is not automatic separation.
Rain, drainage and durability
For exposed work, plan wind-driven rain entry, drainage paths, bases/sills, wetting/drying, frost or salts where relevant, metal corrosion, staining and compatible sealants/cleaners.
Cleaning and replacement
Define safe access, dust and pollutant traps, cleaning trials, allowed chemicals/tools, inspection frequency, repair limits, removal sequence and labelled spare units. “Periodic wipe-down” is not a universal method.
Environmental evidence
Material identity, openings or passive-design intent do not prove lower energy or carbon. Model operational effects where claimed and request product/plant/method/boundary-specific environmental documents.
Use staged samples, mock-ups and an evidence register
Record the reference intent
Mark every archive image external/unattributed. State the desired pattern, colour, depth, openness, orientation, boundary, viewing/privacy and functional aims without assigning a product.
Select an exact current unit
Obtain manufacturer, plant, reference/code, dimensions, body/material, finish, intended use, current status, drawing, representative sample, quantity and quotation.
Build the panel geometry
Develop unit and panel drawings with joints, open-area calculation, repeat/rotation, corners, ends, openings, frame/support zones, movement and interfaces.
Prototype critical details
Use full-size prototypes for cuts/specials, edges, joints, anchors/ties, base/head, movement, tolerances, erection, cleaning, access and replacement.
Test representative performance
Where required, make the mock-up match the proposed units, joints, supports, size, boundaries, conditioning and exposure. Set actions, sequence, criteria, remedy and retest in the project documents.
Control production and handover
Trace drawings, samples, batches, inspections, substitutions, nonconformances and installed locations. Retain approved samples, as-builts, maintenance/access records and labelled spares.
- the 2023 image set does not identify a project, designer, material, product, dimension, supplier or installation system;
- LOPO’s current range labels are inquiry references, not guaranteed factory SKUs or proof that an archive pattern is currently producible;
- an exact block report does not approve joints, frame, anchors/ties, backing/support, guard duty, fire continuity, weathering or the complete panel;
- open area is not by itself ventilation, cooling, daylight, glare, privacy, fire or weather performance;
- mock-ups used for appearance, fabrication/detailing and performance have different purposes and acceptance records; and
- any product, factory, geometry, orientation, joint, support, anchor, finish or installation change requires a written comparison and evidence review.
- Terracotta Jali Blocks owns current range browsing, sample enquiries and exact product confirmation;
- Openwork Light and Shadow develops the visual light/shadow study;
- Openwork Screen Space and Safety focuses on thresholds, occupants and tall-screen safety coordination;
- Red Brick Application Patterns surveys screen, relief, openings and inside/outside pattern families; and
- Downloads and Contact provide current drawings, samples, technical records and project discussion.
