Access and Security: What to Consider When Purchasing Glass Display Cases

/in /by

When investing in glass display cases—whether for museums, galleries, retail, or heritage environments—access and security should be considered together from the outset. A well‑designed case protects its contents from theft or damage while also ensuring safe, practical access for staff and long‑term usability of the space.

Below are the key considerations to address when specifying or purchasing glass display cases.

1. Attack Resistance and Case Construction

Security begins with the structure of the display case itself. Where valuable or sensitive objects are involved, attack‑resistant construction should be considered rather than standard glazing alone.

  • Framed display cases are generally preferred for higher‑security applications, as the frame protects vulnerable glass edges.
  • Laminated glass should be fully supported by the frame, with adequate edge coverage—often in the region of 25–30mm—to reduce the risk of forced entry.
  • Suppliers should be able to confirm whether their cases align with recognised national guidance on attack‑resistant display furniture.

Robust construction forms the foundation of effective display case security.

2. Shelving, Brackets, and Internal Access

Security is not limited to the external shell; internal components play a critical role.

  • Specify multiple shelf support and wall‑bracket options, particularly where object weights or layouts may change over time.
  • Shelves and fixings must be robust, tamper‑resistant, and suitable for the loads they are expected to carry.
  • Poorly designed internal fittings can become weak points in an otherwise secure display case.

3. Safe and Practical Opening Mechanisms

Controlled access for staff is essential for both safety and efficiency.

  • Display cases should be capable of being opened by one trained person, without excessive force or awkward handling.
  • Doors, lids, or sliding panels must operate smoothly, without creating pinch points or risks to people or objects.
  • Consider how access will work in confined spaces or public‑facing areas, particularly during maintenance or object rotation.

4. Plinths, Voids, and Hidden Compartments

Many display cases incorporate plinths or base cabinets for services, storage, or structural support.

  • Access panels or voids within plinths must be designed so they do not compromise the security of the display volume above.
  • Weak access points below the case can undermine even the strongest glazing and locking systems.

5. Locks and Locking Strategies

Locks are a critical component of display case security and should be clearly specified.

  • Allow for at least two locking points on each opening door or panel where appropriate.
  • Common lock types include cam locks, internal cam systems operated by Allen keys, claw locks, mortice locks, hook‑bolt mechanisms, and electronic locking systems.
  • Manufacturers should provide full specifications for locks and locking hardware so suitability can be assessed before installation.

6. Concealed Security Features

In many environments, visible security hardware can detract from the visual impact of a display.

  • Consider whether hinges, reinforcements, and locking devices should be concealed within the case design.
  • Experienced suppliers can integrate security discreetly without compromising structural strength or performance.

7. Alarms and Monitoring

For higher‑risk displays, physical security can be enhanced with electronic systems.

  • Opening panels can be fitted with contact alarms.
  • Case structures may support vibration or shock sensors to detect tampering or impact.
  • Ensure any alarm systems are compatible with the building’s existing security infrastructure.

8. Stability, Fixing, and Structural Loads

Large or freestanding display cases can present safety and security risks if not properly fixed.

  • Island cases or tall structures may require bolting to the floor.
  • Confirm that existing floors can safely support the combined weight of the case, glazing, and contents.
  • This is particularly important in historic buildings or upper‑floor installations.

9. Environmental and Maintenance Considerations

Security should be considered alongside long‑term care and maintenance.

  • Display cases positioned against external walls may require a rear clearance gap to allow for air circulation.
  • If clearance is required, ensure there is adequate access for cleaning and inspection behind the case.
  • Poor airflow or inaccessible areas can lead to long‑term conservation and maintenance issues.

In Summary

A secure display case is not defined by thick glass or strong locks alone. Effective security results from the integration of structure, access, safety, and environmental considerations. By asking the right questions early and working with experienced suppliers, institutions can achieve display solutions that protect objects, support staff, and enhance the overall visitor experience.
