Is Your Privacy Film Private Enough? A Room-by-Room Handover Checklist

Check presence, outlines, identity and readability before sign-off

How do you know whether privacy film provides enough privacy?

Privacy film provides enough privacy when it meets the room’s agreed requirements from the places where people can actually look in, under the lighting and operating conditions in which the room is used. Check separately whether an observer can detect someone’s presence, distinguish a body outline, recognise their identity or read information.

Agree which outcomes matter before installation. Check the completed treatment against those requirements and record any limitations.

A meeting room may allow visible movement while requiring presentation content to remain unreadable. A changing room may require body outlines to be concealed as well. Neither room should be assessed simply by asking whether the glass “looks frosted”.

This checklist is a practical assessment of visual privacy under recorded conditions. It is not a recognised certification or a guarantee of confidentiality.

What should you agree before choosing privacy film?

Agree what must remain concealed, from which viewpoints and under which conditions. The word “privacy” alone does not describe a clear installation requirement.

Use four separate questions:

Privacy outcome	Question to answer	Decision to record
Presence	Can someone tell that a person is inside?	Is visible occupancy acceptable?
Outline	Can someone distinguish a body shape or movement?	Are silhouettes acceptable?
Identity	Can someone recognise the person from their face, clothing or other details?	Must identity remain concealed?
Information	Can someone read text or recognise sensitive screen content?	What information must remain concealed?

These outcomes are related, but one does not establish another. An obscured face may still leave a distinctive uniform visible. A treatment may conceal an occupant while an untreated strip exposes a monitor.

Write the required outcomes down before approving the sample and coverage design. Include any conditions the result depends on, such as furniture position, closed doors or a particular switchable-film setting.

Does a high privacy rating guarantee privacy in your room?

No. A manufacturer’s privacy rating is a comparison guide with stated conditions. It does not establish the result for every room, viewing distance or lighting arrangement.

LLumar’s decorative-film data sheet uses a relative privacy scale from 0 to 10. Its stated basis places both the observer and the object at least two feet, approximately 610 mm, from the filmed pane. LLumar identifies the rating as a guide. A rating of 9 therefore does not mean “90% private”.

If the observer or the person or object being assessed is closer than approximately 610 mm to the glass, that arrangement falls outside the distance basis stated for the rating. It does not automatically mean the film will fail; it means the published rating alone does not establish the result.

Use product information to shortlist suitable films, then assess a representative sample or mock-up against the intended layout.

What should you check in each room?

Start with the room’s activity and the consequences of overlooking. The following checks are suggested starting points. The customer and installer should agree the actual acceptance requirements for each room.

Room or area	Agree before installation	Check at handover
Meeting room	Whether occupancy and faces may remain visible; which presentation content must be concealed	Seated attendees, standing presenter, screen in use and corridor views
HR or interview room	Whether the visitor’s identity or presence must remain concealed	Visitor seating, nearby waiting areas, door glazing and clear borders
Consultation or treatment room	Whether identity, body outlines and displayed information must be concealed	Intended occupant positions, task lighting and accessible external viewpoints
Bathroom or changing room	Whether any recognisable silhouette is acceptable	A fully clothed demonstration at normal and closest intended positions
Home study	Which documents and screen content must remain unreadable	Actual desk position, screen brightness, document size and outside sightlines
Corridor-facing living room	Whether reduced overlooking is sufficient or stronger concealment is needed	Seated and standing occupants under daytime and evening arrangements
Reception partition	Whether partial screening meets the purpose	Queuing positions, decorative cut-outs, clear bands and adjoining glazing

For Singapore homes and workplaces, corridor-facing windows and partitions beside circulation routes deserve particular attention because an observer may have close access to the glass.

Assess the actual access and layout. Do not assume that every corridor, bathroom window or office partition presents the same viewing conditions.

Where should the observer stand?

Check all relevant accessible viewpoints, including the nearest position, normal walking routes and angled approaches. The nearest viewpoint is important, but a different angle through a clear strip may reveal more.

Mark the positions so the assessment can be repeated. Record the observer’s distance from the glass and viewing height.

Include seated and standing viewpoints where relevant, together with wheelchair-height viewpoints if they form part of the room’s surroundings. Ask the person inside to occupy the positions the room is designed for.

A privacy band should be checked against the actual furniture layout. For gradient film, identify which part of the design crosses each sightline. LLumar’s published data distinguishes privacy characteristics across different areas of some gradient products.

How do you check presence, silhouettes and identity?

Ask a consenting colleague to sit, stand and move through the intended occupied area while another person observes from the marked viewpoints. Include the closest position a user would reasonably take beside the glass.

Ask the observer to describe what they can distinguish before revealing who is inside. This helps reduce assumptions based on prior knowledge.
Record observations separately:

• Whether someone’s presence is detectable.
• Whether a body outline or movement is distinguishable.
• Whether facial details are recognisable.
• Whether clothing, a badge or another visible detail identifies the person.

Use precise descriptions. “No outline observed from viewpoint A under the recorded lighting” is more informative than “completely private”.

Can screens or documents be read through untreated areas?

Check the entire glazed opening, including clear borders, decorative cut-outs, spaces between bands and adjacent untreated panes. Privacy depends on the complete sightline into the room.

Use dummy documents and a sample presentation. Include the ordinary text, larger headings, numbers and graphics that the room’s users normally display.

Record the screen position, brightness and sample text size. Ask the observer to describe or read what is visible instead of simply asking whether the screen looks private.

Distinguish between seeing that a screen is switched on, recognising an image and reading its content. Each may have a different acceptance requirement.

Keep doors in the agreed privacy position during the check. Record any exposure caused by opening them as a separate operational limitation.

What should you check with the room lights on?

Repeat the assessment with the lighting arrangements used during occupancy, including a lit room and darker viewing area where that occurs. Do not infer evening privacy from a daytime inspection.
Record:

• Room and corridor lighting.
• Task lights and bright backgrounds.
• Screens in use.
• Blinds or curtains and their positions.
• Daylight conditions and the time of inspection.

If a light meter is used, record the position and direction of each measurement. A single room-wide lux figure does not describe every relevant sightline.

If an agreed lighting condition cannot be reproduced at handover, mark that check as pending and arrange a follow-up.

What must be checked for switchable privacy film?

Check visual privacy and system operation separately. A panel changing from clear to frosted confirms switching, but does not by itself establish that the room’s privacy requirement has been met.

Conventional PDLC film commonly becomes frosted when unpowered and clear when powered. Confirm the behaviour of the supplied product and controls rather than assuming that every system operates identically.

State or function	Handover check
Privacy state	Repeat the agreed checks for presence, outlines, identity and information
Clear state	Compare appearance and visibility with the agreed sample
Multiple panels	Confirm that every required panel changes state correctly
Switches and remotes	Check that each control operates the intended panels
Dimming, if supplied	Assess each setting intended for privacy use
Timers and automation	Check whether automatic actions can change the room to clear during occupancy
Power interruption	Have the installer safely demonstrate and record the resulting state
Power restoration	Record whether the system returns to its previous state or another default

Control options vary. Gauzy, for example, documents individual and grouped panel control, dimming and automation integration. Assess the functions actually supplied for the installation.

Agree who can change the settings, which overrides are available and what users must do before relying on the privacy state.

How should you record the handover result?

Use one record for each room, repeated for every required lighting condition and operating state. Record observations first, then compare them with the agreed acceptance requirements.

The table below is a blank template, not a set of demonstrated results.

Enter Yes, No, Uncertain or Not checked, with explanatory notes where needed.

A “Yes” is not automatically a failure. Visible occupancy may be acceptable even when identity and information must remain concealed.

Record the acceptance decision separately as Meets agreed requirement, Does not meet agreed requirement or Pending. A required condition that remains uncertain or unchecked should remain pending.
Keep the following with the record:

• Room identification, film product and coverage drawing.
• Agreed privacy outcomes.
• Date, time, lighting and operating state.
• Observer and target positions, heights and distances.
• Document or screen sample used.
• Observers’ names, outstanding actions and recheck date.

Photographs support the record but do not replace direct observation. For comparisons, keep camera positions and settings consistent and record any changes.

What if the film does not meet the agreed requirement?

Identify the condition that failed before choosing a remedy. The issue may involve the film, coverage, viewing angle, room layout, lighting or switchable controls.

Possible changes include revised coverage, a different treatment, repositioned sensitive content or a suitable blind. Check that the remedy allows the room to function as intended.

Repeat the affected assessments after correction and record the result. Do not silently lower the acceptance requirement to match the installation.

Recheck when furniture, lighting, screens, coverage or control settings change. These changes may alter the conditions on which the original acceptance was based.
