Privacy film for an apartment facing another tower

When the building across the street looks straight into your living room, film on the glass can stop the view in and still let the daylight through. In a strata building, how that film looks from outside matters as much as how it works inside, so that is where we start.

Two apartment towers across a street. A line of sight from a window in the tower opposite reaches your living room glass and stops at a frosted band of film. Above the band the glass is clear, and daylight comes in. THE TOWER OPPOSITE YOUR UNIT LIGHT IN THE STREET BAND STOPS THE VIEW IN

Four privacy films, and how each looks from the street

Your committee and your neighbours see the outside of the glass, so each film here is described three ways: what the tower opposite sees by day, what it sees at night, and what the building looks like from the footpath.

The street face of an apartment building, four floors of four windows. On one floor the windows show the four films from outside: A has a pale band across the middle, B is pale all over, C is mirrored, D is slightly darker than the plain glass around it. ABCD YOUR FLOOR

What your strata committee will ask

The NSW Government's strata renovation rules sort work in a unit into three kinds. Cosmetic work needs no approval, but only when it does not affect the outside of the lot; blinds and curtains are among the examples. Minor renovations need approval from the owners corporation, and major renovations, which include changes to the outside, need a special resolution at a general meeting.

Film appears on none of those lists, and a scheme's by-laws can add items of their own. Privacy film is also the kind of film people can see from the street. So the answer for your building sits in your by-laws and with your committee, and we suggest putting the question to them before the install, not after.

Whether your film needs approval is the committee's call, and we will not guess it for you. What we can do is hand you everything they need to decide.

What we give you for the committee

  • The panes, by room and by side of the building
  • The 3M film named for each pane
  • How each film looks from outside, by day and at night
  • The band height, if you choose a band
  • Film on the inside face only, and removable
  • Who does the install, and the access it needs

The three kinds, NSW strata rules

Cosmetic workNo approval, if it does not touch the outside or the structure
Minor renovationMore than half the votes at a meeting, or the committee if a by-law hands it the decision
Major renovationA special resolution at a general meeting

Privacy by day and at night

Every privacy film that lets light in depends on which side of the glass is brighter. By day the street and the sky outshine your living room, so the tower opposite sees the film, not the room behind it.

After dark, with the lamps on, that flips. A frosted pane shows a glow and soft shapes near the glass. A reflective pane shows the room itself, and from inside it turns into a dark mirror. A blind or a curtain is still what covers a window at night.

What film changes is the daytime. The blind can stay open from morning to evening, and the room keeps its daylight while the building opposite loses its view in.

By day, seen from the tower opposite: a reflective pane reads as a mirror and the room behind it cannot be seen.

Where the tower opposite looks from

The right film, and the right band height, depend on whether the windows across the street are level with yours, above them or below. We stand where you sit and look back at the building before anything is chosen.

A window level with yours: the straight-across view meets the frosted band.

Level with you

A frosted band across the middle of the glass takes the straight-across view. Its height is set from where you sit and stand in the room, not from a standard line.

A window above yours: lines of sight pass down through the clear glass above and below the band, reaching the floor of the room.

Above you

From higher up they look down through the whole height of the glass, into the floor, the table and the sofa. A band at eye height misses most of that, so these panes often want frost higher up, or all over.

A window below yours: the line of sight rises into the lower part of your glass, where a lower band stops it.

Below you

From lower down the view in is mostly ceiling, and anyone standing close to the glass. The lower and middle glass matters, and the top can stay clear for the sky.

A unit on the schedule

A privacy job in a tower is rarely every window. It is usually the two or three panes the building opposite can see, with the rest left clear or given a light tint so the room still matches from outside.

The quote is written from this schedule, one pane at a time, with the film for each. The amount of glass, the film on it and getting to it are what move the price, and in a tower getting to it includes the lift booking and where the van can park.

Heat or glare in the same room? Heat and glare in a unit goes on the same schedule.

Unit privacy done badly

Reflective film for privacy

Reflective film chosen for privacy works until the lamps go on, then shows the room. It also changes how the building looks from the street.

The band at a stock height

Set without looking back at the building, the band hides a strip of glass the neighbours were never looking through.

Film first, committee second

If the film needed approval and never had it, the owner can end up paying to take it off.

Every pane frosted

The whole room turns milky when only the panes facing the tower needed it. The light stays and the view out goes.

Questions about privacy film in a unit

Will the people opposite see in at night?

With the lamps on, to some degree, yes, whichever film you choose, as long as it lets light through. Frost shows a glow and shapes; reflective film shows the room. Keep the blind for night, and let the film do the daytime.

Do I need strata approval for privacy film?

We cannot answer that for your building, and no general rule can either. Your by-laws may name window film or window coverings, and NSW lets each scheme add to its lists. Ask your strata manager or committee. We give you the panes, the film and how it looks from outside to take to them.

I rent the unit. Can I have privacy film put on?

Ask your landlord first. In a strata building it is the owner who goes to the owners corporation, so they will want the film details too. Film can be taken off later, and it is worth agreeing in writing who does that when the lease ends.

Can I still see out?

By day, through reflective film and a light tint, yes. Through frost, no: it lets the light in and stops the view both ways. A band keeps the view out above and below it.

Other units in our building already have film. Can ours match?

Tell us which units and which side of the building, and we note it on the schedule so the film is chosen to match. One look across the building is also one decision for the committee, not one per unit.

Tower suburbs we measure

In North Sydney, St Leonards, Chatswood and Hornsby most homes are flats or apartments, and in North Sydney new towers are still going up along Miller Street beside the older ones.

Privacy on a house instead: street-facing sidelights and bedrooms. For the committee in more detail: film in a North Shore apartment.
