5 Window Film Myths

A clear understanding about window film and recognizing what they can and cannot do is vital to making your installation decision. Read below about a few of the myths, and many of the real-world benefits of window films below. You might be surprised by what you find.

Looking into the Past

Window film was initially invented for use in space. This out-of-this-world fact actually makes sense when you consider the selective heat rejection properties of window film. In space, craft are subject to temperatures ranging from -240C to over 200C. Reflective tint was developed to help spacecraft tolerate these astronomical temperatures.

Commercial building applications of this type of window film began in 1966. Tint before ’66 had little heat reduction properties, and therefore couldn’t contribute meaningfully to energy savings. Tint was improved again in 1976 by the addition of reflective coatings.

Modern window film can provide nearly 80% heat gain reduction, and therefore significantly reduces energy costs. To skip the myths and get straight to the info, check out this page.

Utilities are usually the single largest source of energy consumption in a household both in the summer and the winter months, and installing window film can greatly reduce this financial burden, no matter what season you are in.

Window Film Myths

Building managers and business owners often have concerns about window film that are not founded in fact, or are completely outdated. Here are a few common myths about window film, so we can all get on the same page.


Myth: Window film will cause seal failure in insulated units.

Fact: For more than 40 years window film has been applied to millions of square feet of insulated glass and has never been demonstrated to cause seal failure. Federal specifications require that windows be able to tolerate a minimum of 3.30 psi, and window films will only cause a pressure increase of around 0.55 psi – that is a sixth of what the window can comfortably tolerate. Many manufacturers offer warranties against seal failure.

Myth: Window film will cause thermal glass breakage.

Fact: Window film can only contribute to thermal glass breakage if the glass was not manufactured or installed to industry standards in the first place. Many manufacturers and installers offer warranties to protect against thermal breakage.

Myth: Window film is a short-term solution to a long-term problem.

Fact: Modern high-quality films have abrasive resistant coatings and advanced adhesion technology that ensures high performance for more than 20 years. After a few decades, the film can easily be removed and replaced.

Myth: Window film quickly discolour.

Fact: High-quality window films use ultraviolet inhibitors to protect against discolouring. The notion that window film will quickly discolour is extremely outdated, and only applied to poor quality film.

Myth: Reflective films inhibit viewing out of windows at night or during low light conditions.

Fact: Newer products allow perfectly clear viewing during night time and low light conditions, in addition to enhanced solar protection. Our heat reflective films won’t obscure your ability to see out your windows – the only thing they block is solar radiation.
