Choosing a film

Which way does the glass face, and when does it bother you?

Aspect does more work than any other single factor, and in Melbourne it has a particular character.

West is the hard one. Low afternoon sun, straight in, at the end of a day when the room has already been warming for hours. West facing glazing is where most heat complaints come from and where film makes the most dramatic difference.

North gives a long, even exposure through the middle of the day. Less brutal than west, but it goes on for hours and it is the aspect most likely to be doing quiet damage to timber and textiles.

East is a sharp morning event. Rooms that are perfect by lunchtime can be unusable at nine. East facing offices often have a serious glare problem and almost no heat problem.

South rarely needs solar control at all. If a south facing room is the reason you are calling, the issue is usually privacy, appearance or safety rather than sun, and we will specify accordingly.

Then the question underneath it: at what hours does this actually trouble you? A room that is difficult for one hour in the morning needs something different from a room that is difficult from three o'clock until sunset.

What are you actually trying to fix?

Most people arrive with one of five problems, and it is worth naming yours before any film is discussed.

Heat that builds through the afternoon. Glare that makes screens or pages unreadable. Colour fading out of floors, rugs and furniture. Privacy, whether during the day, after dark, or both. Glass that needs to hold together if something hits it.

Several of these often apply at once, and sometimes they pull in different directions. The film that preserves your daylight is not the film that kills glare. The film that gives you daytime privacy does nothing in the evening. We would rather have that conversation out loud and choose with our eyes open than quietly optimise for the wrong one.

What is the glass?

This is the question that most often changes the answer, and it is the one that genuinely cannot be settled from a website.

Single glazing, sealed double glazed units, laminated panes, toughened glass, glass that is already tinted and glass that spends half the day in shade all behave differently under film. Some combinations of film and glass carry a real risk of thermal stress, and that risk is a physical one rather than a theoretical caution written to cover somebody.

So we confirm what your glass is and what is appropriate for it before anything is quoted. When we are unsure, we say we are unsure and find out, rather than specifying hopefully.

How do you want the room to feel?

This is the part people are often surprised to be asked, and it is frequently what separates two technically valid options.

Do you want the room to keep feeling bright, or would you be happy for it to be a little more subdued if that made it more comfortable? Is the view something you look at deliberately, or is the window mostly a source of light? Does the glass carry the character of the room, or is it simply there?

There is no wrong answer. But a film chosen purely on performance, with no regard for how the room reads afterwards, is how you end up technically satisfied and quietly disappointed.

How should the building look from outside?

Reflectivity is a specification choice that runs from barely noticeable to distinctly mirrored, and it is yours to make.

On a house, most people want the glazing to look much as it does now, perhaps a shade deeper, with no mirror effect from the street. On a commercial building, a consistent appearance across every elevation often matters more than the performance of any single pane, because mismatched glazing on a facade is visible from the other side of the road.

Tell us how you want it to read and we will specify to that.

Is anybody else involved in the decision?

Worth checking early, because it occasionally changes what is possible.

Owners corporations and bodies corporate sometimes have rules about the appearance of glazing from outside. Heritage overlays can too. If you lease the building, the owner or the managing agent may have their own requirements, and it is far easier to ask before work is booked than afterwards. Film is applied to the surface of the pane and can be removed later, which is usually the point that settles those conversations.

What a good specification looks like

By the time you are reading a quotation from us, it should name the film, the glass it is going on, and what it will and will not do. If it does not, you are being asked to buy a label rather than a decision.

You should also be told plainly where a film is a compromise. Almost every job has one: a little less daylight in exchange for usable desks, daytime privacy with a blind still needed at night, heat solved on the west elevation while the north gets something different. Knowing the compromise in advance is the difference between a trade you accepted and a surprise you were handed.

And sometimes the answer is no film

If the real problem is a draught, a cold room in winter, poor ventilation or a dark roof, film will not fix it, and we will tell you that rather than sell you something that cannot work.

It costs us a job occasionally. It is still the right call, and it is the only basis on which the rest of what we tell you is worth anything.
