A French or Juliet-style balcony may look like a normal balcony in a front photograph, but its usable geometry is different. The exterior guard can sit immediately outside a door or window, leaving little depth for a person, tools, edge treatment, or later inspection. The opening can move inward or outward, the guard may be separate from the building structure, and the top and side reveals may be shallow. A useful quotation therefore needs an elevation, depth section, moving-element map, material notes, access plan, and installer confirmation rather than one width and height.
Confirm What Kind of Boundary Exists
Start with photographs from inside and, only from a permitted safe location, views that explain the exterior guard and facade. Record whether the primary opening is a door, full-height window, paired leaves, tilt-and-turn unit, or another configuration. Mark which parts move and where handles, locks, restrictors, sills and drainage paths sit.
Never treat the guard as an automatic fixing structure. Identify visible materials and connections, then mark unknown substrates for installer verification. Building management and local requirements control whether and where work is permitted.
Draw an Elevation and a Depth Section
Use the broader cat net measurement guide for width, height, diagonal and photo records, but add a side section showing the distance from the inner frame or wall plane to the guard. Record reveal depth at top, both sides and sill because it may vary.
Name the possible net plane rather than assuming it. Show the opening plane, guard plane, facade returns and any space between them. A supplier can then ask whether a boundary is reachable and continuous without guessing from perspective.
Map Every Moving Path
Open doors or windows only under normal safe use and record the complete path, handle projection and any cleaning or maintenance position. Check whether the proposed boundary would interfere with opening, locking, ventilation mode, curtains, blinds or authorized emergency use.
The drawing should distinguish required daily movement from rare service access. If the only installation path is through the opening, show the clear dimensions and how access would be managed by a qualified installer.
Record the Guard Without Relying on It
Measure visible guard width, height, post positions, rail profile, offsets and gaps as context. Photograph brackets and connections without making structural judgments. The net boundary may relate to the facade, reveal, guard or a separate approved system, but that decision belongs to the installer and building authority.
Avoid placing a tape, body weight or equipment outside the protected interior merely to obtain a dimension. When a critical exterior measurement cannot be reached safely, label it for site verification.
| Survey Plane | Record | Why It Matters |
|---|---|---|
| Opening elevation | Widths, heights, diagonals, moving leaves | Defines visible geometry |
| Depth section | Frame-to-guard and reveal offsets | Shows the shallow working zone |
| Exterior guard | Posts, rails, gaps, material notes | Explains interfaces, not fixing approval |
| Proposed boundary | Top, bottom, sides and interruptions | Tests continuity |
| Access route | Reach, equipment, permission and timing | Supports installer planning |
Choose Material Only After the Boundary Is Understood
MaxCatNet's current product scope includes transparent nylon cat net and stainless-steel-wire-reinforced cat net. The material decision should consider visibility, expected cat behavior, handling, edge design, environment, installer method and buyer requirements without claiming absolute escape prevention.
Never select material to compensate for an unresolved edge or inaccessible fixing line. A strong product description cannot make an incomplete boundary suitable.
Plan Installation and Future Inspection Access
Ask how the installer will reach the top, sides and lower boundary; protect occupants and public areas; move through the opening; control tools; and confirm completed edges. Also ask how the installed net, edge and fixing points can be viewed later without unsafe leaning or removal of building elements.
If access equipment, facade work or external permission is needed, record it as a project gate. Product cutting should not begin while a critical boundary remains inaccessible or unverified.
Issue a Quotation Pack With Open Questions
Provide the plan, elevation, depth section, dimension table, numbered photos, opening sequence, guard context, visible substrates, preferred material, access restrictions, building permission status and unknowns. Ask the supplier and installer to return the proposed panel and boundary logic on a marked drawing.
The final site check should confirm critical dimensions, actual substrate, fixing method, movement clearance and access. Keep revisions dated so a facade or door change does not leave production using an obsolete survey.
Use a Remote Survey Only as a Defined Preliminary Stage
A French balcony is often difficult to access from outside, so buyers may begin with resident photos and interior measurements. Define that stage as preliminary. Provide a photo guide showing safe interior viewpoints, required opening positions, guard and reveal views, tape endpoints, depth-section references and an guidance not to lean outside or bypass a restrictor. The resident should be allowed to mark a field unavailable rather than attempt a risky measurement.
The supplier can use the preliminary pack to identify likely panel geometry, material questions, access needs and critical unknowns. Label all quotation dimensions as client reported until the project procedure verifies them. If a photo hides the top edge, exterior face or guard connection, list that gap openly.
Before production, a responsible installer should confirm the actual opening, boundary plane, substrates, movement path and access method. Compare verified values with the preliminary record and issue a revision. This two-stage method preserves the convenience of remote planning without pretending that perspective photographs or an untrained exterior measurement are a final installation survey.
Release the Survey Through the Installer
The installer should sign the verified opening, proposed boundary plane, access method, substrate review and moving-element clearance before the supplier cuts the panel. Building permission and unresolved exterior details remain explicit gates. Keep the resident's preliminary pack as context, then archive the installer revision as the controlling site record. This preserves convenience without confusing remote measurements with final approval.
Record Cleaning and Window-Maintenance Interfaces
Ask how residents or building contractors currently clean glass, inspect seals, service handles and reach the exterior guard. Mark panels, openings or access routes that those tasks use. The net proposal should not silently remove required maintenance access or encourage unsafe leaning. Where access must change, the building manager and installer should define an approved method and explain it at handover. Record the responsible party for later facade or window work so the net is reviewed before contractors remove, loosen or work around its boundary.
Buyer Checklist
- Identify the opening type and every moving element.
- Draw both an elevation and a depth section.
- Measure reveal and guard offsets at named locations.
- Record guard details as context, not automatic fixing approval.
- Mark inaccessible dimensions for qualified site verification.
- Choose net material only after boundary and access review.
- Obtain installer and building confirmation before production.
Frequently Asked Questions
Is a French balcony measured like a normal balcony?
It needs the usual opening dimensions plus shallow-depth, guard-interface, movement, and installation-access records.
Can the exterior guard be used for fixing?
Only after the responsible installer and building authority confirm the actual structure and permitted method.
Can photos replace an exterior measurement?
Photos provide context, but critical geometry that affects fit or access must be safely verified.
