Automotive Window Films

Automotive Window Films: Why Does Auto Tint Fail?

We’ve all seen that car driving down the road. You know, the one where the windows are purple, and not because the driver is paying homage to a sunglasses trend from the early 2000s. No, this car has a rear window covered in waves and bubbles. Without question, that person got a bad auto tinting job.

Just as good automotive window films add flair and class to a vehicle, there are few things that knock down the aesthetic value of your car like a bad tint job. The same is true for peeling clear-coat on the surface of your car, which often goes hand-in-hand with failing tint.

We at Tint Tech understand all too well the dangers of a bad automotive window film application.  We understand that your car is your pride and joy, and we want to make sure that every automotive window film application enhances – not detracts – from the good looks, lines, and contours of your car. That is why Tint Tech, Calgary’s top automotive window film shop, does a marvelous auto window tint job the first time, every time.  Call us for more information at 1-403-968-8468, or be sure to fill out our online contact form.

Now, let’s answer that important question – What causes automotive window film to go bad?

Cause #1 – The Sun

The radiation from sunlight is the primary reason that tint will bubble, crack, peel or turn purple.  Auto tint’s number one job on your vehicle is to block rays from the sun, in the form of radiation you can see (visible light) and radiation you cannot (ultraviolet and infrared).  Like everything else that blocks light, it does so in one of two ways:  (i) by absorbing light, or (ii) by reflecting light.  Unless you have a reflective metallic tint, it is more likely that your automotive window films are going to absorb the radiation as the method of keeping it out of your car.

Over time, the UV radiation starts to break down the adhesives in the auto tint film.  That includes both the adhesives used to apply it to the windows directly, and any bonding materials between the layers of the film itself.

For that reason, automotive window film will peel away from the glass (also known as “delamination”), and you will also see bubbles inside the film itself.  Even if you could somehow re-attach the film back to the window, those bubbles remain.  Notably, those same UV rays can also be blamed for the delamination of the clear coat on the exterior of the vehicle.

Cause #2 – Old or Low Quality Film

The older your car is, the more likely that an out-of-date film was used to tint the windows. Those films typically incorporate dyes between a few layers of plastic film and were never intended to last for the lifetime of the vehicle. The sun’s rays break down those dyes the longer the film is subjected to the heating and cooling cycles of day and night.  The film typically turns purple, blue, or a faded gray, after prolonged exposure to the sun.  That can take only a few years in some cases.

Many modern, high quality films typically incorporate either carbon or ceramic particles. Because those films have no dyes in them, they are more resistant to fading than the classic films. Ceramic tints are the most expensive that you can buy. So, it is worth discussing with your tint installer the potential benefits of a carbon film versus a ceramic film.  If your car is out in the sun most of the time because you do not have access to covered parking, that may make ceramic a better option. Yet, do your research on the different films and don’t allow yourself to be talked into a higher-ticket item if you do not need it.

Cause #3 – Poor Installation

If the tint was not applied properly in the first place, your vehicle is at a higher risk of having the tint fail.  There are a number of sites on the car where the tint is at risk for delamination due to improper installation or care instruction. The top three are (i) the defrost bars on the back window, (ii) the dot matrix at the edges of windows, and (iii) the film on moveable windows.

The defrost bars on the back window are wires that supply heat to clear up condensation and melt ice.  For that reason, they represent a three-dimensional (3D) structure around which the tint film must be applied.  Because those are large areas where the film needs to be pressed down, they are at the highest risk for peeling or bubbling, and often the reason long waves or bubbles show up on the rear window of the car more often than any other area.

Likewise, the dot matrix is a 3D structure, but rather than produce the large parallel bubbles like those around the defrost bars, the tint here is more likely to come away in a zigzag pattern if the shop did not either sand down the dots a little prior to the install, or did not use extra adhesive in the areas covered by the dot matrix.

The film on the inside of the windows can fail if the windows are rolled down prematurely following the install.  It takes three to five days for the film to adequately bond to the glass. Using the windows during this time period can introduce lifting, which causes more problems down the line.

Protecting Your Investment in Your Automotive Window Film – Tint Tech Can Help

There are steps you can take to help prevent your tint from fading.  Though most modern films come with a warranty somewhere between three years and a lifetime for the durability and colorfastness of the tint, you can minimize the possibility of damage by doing the following:

  • Keep your car out of the sun as much as possible. If you needed an incentive to clear out your garage, then park your vehicle where it will not be exposed to UV radiation to reduce the amount of light the tint is exposed to, and to extend the life of the product.  A carport or awning will help serve the same purpose and is better than nothing at protecting the tint film.
  • Do not use harsh or abrasive cleaners on the insides of your windows. Chemical or mechanical surfactants will shorten the life of your tint considerably. Some compounds will even hasten the fading or color change of the tint by directly breaking down the plastic of the film.
  • Review your warranty.  If your tint comes with a warranty from the manufacturer or installer, keep the paperwork in a safe place so that if you do start to notice fading, peeling, purpling, or other signs that your tint is starting to fail, you can make use of the guarantees offered to you at the time of purchase.

So, there you have it.  A list of reasons why tint fails, and a good set of to-do items to make sure that your tint job won’t be the proverbial car driving on the road with the peeling, purple, bubbling window tint.  For the best results, call the professionals at Tint Tech.  You can reach us at 1-403-968-8468, or if you fill out our online contact form.

Car Glass Tinting: What to Look for In the Finished Job

So, you decided to get the windows tinted on your car.  You looked into all the local vendors, learned more than you probably wanted to about visible light transmission, researched what areas of your car your state will allow you to tint, and decided how far you wanted to follow the rules.

Perhaps you went to Calgary’s premier car glass tinting shopTint Tech – to get the windows tinted.  Now you ask yourself – “how do I know that I got my money’s worth from the shop?”  While we at Tint Tech guarantee all our work, you still want to make sure the auto tint was done right the first time – no matter where you get your car glass tinting done.

Here is a helpful checklist to make sure that your car glass tinting is top notch.

Step 1 – Check the Heat Transmission

Open the car door and stand so you have one hand in the direct sunlight, and the other in the shadow of the window.  Many modern, high quality films are designed to block UV and infrared rays from the sun, and you should feel that the hand behind the window is significantly cooler than the one in the sunshine.  This is the biggest return you will get on your investment in window tinting. A good quality tint will protect the fabric and plastic that make up your interior from breaking down as quickly (old car smell, anyone?).  It will also provide you with a more comfortable environment in the summer so your air conditioner won’t have to work as hard to cool the car.

Most people elect by personal choice or state regulations to tint the rear windows and rear windshield more heavily than the front side windows. Check the heat transmission on whichever window has the lightest tint and allows the most visible light through.  It is important to remember that the ability to block these invisible rays from the sun is not necessarily tied to how dark the tint is.  You don’t need to look like you’re driving in a limousine, and you can have a film on the front side windows light enough to allow 70% of visible light penetration and still have the benefit of this protection.

Step 2 – Check Overall Visibility

Sit in the car and check your field of view.  Move your head back and forth as you look out your driver side window, passenger window, and rear window from the point of view of the driver. Are there any obvious ripples in the tint?  Climb into the back seat and repeat with the back doors and rear windows. Make sure there is no distortion when looking through the tinted glass at various angles because this could pose a safety hazard on the road.

Step 3 – Inspect the Defrost Bars

Check for any gapping or bubbling around the wires on your rear window that provide the defrosting action.  Because these present a raised surface, a hasty install may not adequately adhere the film to the window, and provide the seed for separation between the film and the glass that will only get worse over time and distort your field of view.

Even without signs of obvious gapping, with the edge of a credit card or a fingernail, gently press on the film near the wires in several spots.  Check to see if there is visible flexibility in the film, or if you can hear it sticking to the window briefly before pulling away again.  If either of those are the case, ask questions of the installer.  Did they use extra adhesive to fill in areas covered by the dot matrix?  Are they willing to go over those areas again to make sure they are secured to the window properly?

Step 4 – Inspect the Film Near Window Edges

There is a caveat associated with this advice.  You should not roll down your windows for 3-5 days after the film is applied.  This waiting period ensures the sheet has bonded fully to the window glass, otherwise you risk introducing lifting or scratches to the film.

While at the shop, you can check the visible edges where the film terminates near the sides of the rear window, and by the frame and weather-stripping on the doors.  You are looking for a clean, even line that follows the edge of the window without wavering or fading.  Faded spots may indicate that a section of film was stretched or put under other stress during installation and presents a possible point of failure.

Once the cautionary period has passed, roll each window down slightly and check the edges of the film at the top edge of the window. Like the other edges, the tint should terminate in a sharp, clean line that follows the contour of the window edge without wavering.

Step 5 – Double-Check Your Paperwork

While you’re waiting for the tint to be applied, look over the documents you signed and see if the shop or the tint manufacturer offers a warranty on the tint.  Tint Tech does offer certain warranties, so check with the installer if Tint Tech is installing the car glass tinting for you.

If your installer does provide warranties, verify what is covered with regard to the materials and labor cost, and how long it is valid.  If there is a warranty period, perform the same checks at regular intervals of 3-6 months for the duration of the warranty to make sure there is no delamination of the film, cracking, bubbling, or other failure.

Make sure you keep the warranty paperwork in a safe place, but not so safe that you forget where it is.  Window tint is an investment in your car far beyond the aesthetic benefit, and it is worth protecting.

Finally, Protecting Your Tint

Professional car wash establishments should know how to care for tint when cleaning and detailing the interior of your vehicle.  If you like to be more hands on about your maintenance and wash your own car, remember not to use anything abrasive on the interior glass to maintain the integrity of the tint film. A microfiber cloth and a mild cleanser will be more than enough to clean the windows and keep from scratching the tint so you can continue to enjoy it for years to come.

Today’s article is going to change all that.  Today we will focus on the “Silent Bob” of the window tinting world – office tinting.  In fact, after reviewing this blog, you will come to realize that office tinting is the best kept secret in the window tinting world.  It is a marvelous product with amazing benefits.

What Makes Office Tinting So Amazing?

Office tinting has a host of benefits for office management and employees alike.  This blog will touch upon just a few of the reasons why you should look into investing in office tinting for the windows in your building.

First and foremost, once you go through the benefits of office tinting, you will see that there is virtually no downside.  There are few products that can boast such a claim.  But with office tinting, you are looking at all positives that will help your environment, and the bottom line.

Benefit #1 – Aesthetics

What do building owners and property managers do?  They trim the trees and hedges, maintain the grass, power wash the sidewalks, and generally make the property look as good as possible.  That is because it is important for the business and the area to have an attractive place to work.

Well, why not add a real boost to the look of your office building?  Office window film is just the thing to enhance the aesthetic beauty of an office building or office complex.  Indeed, adding reflective or slightly darkened window tint to your office building will give the building that upgraded look, without the massive cost of renovations.

Benefit #2 – Improved Security

Window film, whether it is reflective or darkened in whatever color you wish, brings added security to the office building.  Why?  Because would be burglars cannot see through the windows – particularly those on the first floor.  While computers and other expensive office equipment would normally be in view if someone looked through an office window, darkened or mirror window film would make it impossible for someone with nefarious motives to see if there is anything to steal.  That creates a huge disincentive for a would-be burglar, because a person will not typically take the risk of illegally entering a building if there is no way of knowing that there would be something worth stealing once inside.

Benefit #3 – Privacy Makes Perfect

Employees do better when they are not working in a fishbowl. Office tint will allow your office’s windows to be darkened to maintain privacy, but still let employees see out to enjoy the view.  That added privacy for your employees is just the type of benefit that improves the overall workplace, and just for the price of office tinting film.

Benefit #4 – Go Green

There are, without question, marvelous energy efficiency benefits to office tint on your windows.  Office window film has multiple impacts – it keeps UV rays and the hot sun from coming in, thereby giving your air conditioning system relief from having to work hard against the heat from the mid-day sun; and it insulates the windows to keep more of the air-conditioned air in, again ensuring that your air conditioning system does not need to work as hard.  Taking the added pressure off of your heating and air-conditioning system will result in immediate energy savings, and saved money as well.

Benefit #5 – Glare Mitigation

We all know that there are times during the day when direct sunlight will hit your computer screen.  Having that unvarnished natural light can be pleasant, but not if you cannot see the information on the computer screen in front of you.  Office tint takes away that problem by significantly reducing glare.  That way your employees can be more productive throughout the day.

Benefit #6 – Added Safety

It is a somewhat tangential benefit, but window film also protects the integrity of your office windows.  Many buildings are surrounded by trees, which could do harm to a building during a storm. Office tint film, however, is instrumental in keeping a window together if an object hits it.  Keeping glass from shattering will make it safer for those employees who work right next to a window.

Busting the Myths on Window Tint

  • Can you actually see the Great Wall of China from space?  Of course not.
  • Does adding salt to water make it boil faster?  Nope.
  • Will cracking your knuckles mean you are destined for a life of arthritis?  Not a chance.
  • Will dropping a penny from the Empire State Building kill someone?  No murder here.
  • Are bats blind?  No, they see fine but prefer to use echolocation in dark caves.
  • Will you get sick if you swim right after you eat?  No way, no how.
  • Do Twinkies have no expiration date?  Only in our dreams.

What do all of the above have in common?  They are all really popular myths – or as we used to say “old wives tales” – that really do not bear out under real scrutiny.

Indeed, no man-made structure can be seen from space.  There has never been a study conclusively connecting cracking knuckles to increased risk of arthritis.  A penny was actually dropped from the Empire State Building on the popular television snow Mythbusters.  The penny dropped at about 64 miles per hour, but only did minimal damage to its ballistics dummy target.  And finally, Twinkies actually only stay fresh for about 25 days.  So much for having sweet snacks in your bunker when you are waiting out nuclear winter.

What does all this have to do with car window tint, or the best car window tint shop in Calgary – Tint Tech?  The answer is that there are a number of really interesting myths about car window tint that we think it is high time to debunk.

Accordingly, this article will be like our very own private mythbusters where we at Tint Tech look at the top car window tint myths and give you the real deal.

Once you enjoy learning the fascinating misnomers in the car window tinting world from this article, take the next step and give us a call to see what we at Tint Tech – Calgary’s best car window tint shop – can do for you.  There are so many marvelous choices to add the extra something to your favorite ride.  Let us at Tint Tech help you out.  Call us at 1-403-968-8468, or fill out our online contact form.

Myth #1 – Car Window Tint Film Does Not Last Long

We have said it before in previous blogs, and we’ll say it again.  Gone are the days of the old-style car window tint that looked faded, greenish or purpleish, cracked, bubbly, uneven, and peeling.  Those window tints were the car window tints of old.

The technology now used to create car window tint, and residential/commercial window tint for that matter, is amazing.  Incredibly sophisticated processes are employed to make sure that window tint lasts a long time, has UV-protection qualities, and won’t crack or peel for the life of the car.

In fact, many window film products have warranties of up to 15 years!  So, when anyone tells you that car or residential window tint will fade, crack, peel, or look bad after a short period of time, tell them about that Twinkie expiration date – it will blow their minds.

Myth #2 – All Types of Window Tint Have No Benefit in a Storm

Au contraire!  Window tint, particularly residential window tint, brings a host of storm protection benefits that are legitimate and tangible.  Here are a few:

  • It can hold glass in windows together to prevent shattering if something hits a window in a storm.
  • It can help prevent physical harm to passengers of a car, or people inside the house.
  • It can help prevent high winds from entering a home.
  • It is a good front line of defense if there is not enough time to install shutters before the storm.

That said, don’t get cocky.  Window tint cannot do it all.  Here are some things that it might not be able to do in a storm:

Window film can’t keep glass from breaking

It shouldn’t be relied on as the sole source of storm protection.

Window film does not entitle you to a “hurricane mitigation discount” on your homeowner’s insurance policy.

Myth #3 – An Intruder Can Get Right Through Window Film

Many skeptics look askance at the notion that window film – that very thin layer of poly-urethane film over a window’s surface – can do anything to stop an intruder from breaking into your car or home to steal stuff.  Not so!

Safety window film alone will normally not stop an intruder cold from making an illegal entry through your car or home window.  Yet, safety film is designed to hold together and stop a window from shattering into fragments.

The ability to keep the window from shattering and/or breaking through has a distinct potential to delay an intruder’s entrance – maybe long enough for a triggered alarm to get the cops there before the intruder can complete his or her plan.  Further, a savvy intruder may avoid a window with safety film altogether, knowing the problems it could cause for his or her criminal designs.

Myth #4 – Any Energy Savings from Window Film is Minimal

In fact, the energy savings achieved by using window film in a home or office can lead to up to a 70% return on investment.  That is a substantial savings and is right in line with the kind of energy savings tools we need to help the planet overall.   Imagine for a moment if every home in the world was treated with window film so the use of energy drops significantly in the aggregate.

Tint Tech – The Best Car Window Tint Shop in Calgary Is Ready to Help You with Both Auto And Residential Window Film. 

It is fun to bust some myths.  And, in fact, knowing the truth about window film will only make the car and residential window film products Tint Tech provides that much more desirable.  With energy savings, security, and UV protection elements, car and residential window film is the way to go.  We welcome you to call us to learn more at 1-403-968-8468, or fill out our online contact form.

The Foundation of Window Film – PET

Every type of window film – whether it car, residential, or commercial – uses a base polyester film as its foundation.  Just to get a little technical for a moment, the polyester film is produced from a polymer called polyethylene terephthalate, which is commonly referred to as “PET.”  Ultimately, PET, which is initially derived from petroleum, is your window film foundation.

The form of the PET is quite fascinating.  The PET starts in pellet form.  The pellets are then melted to start the window film manufacturing process.

Why Use PET?

The benefit of PET has to do with all the uses for window film.  PET has excellent optical clarity and is exceptionally strong.

With regard to optical clarity, you want a window film that is perfectly clear, but for the dyes you wish to add to darken the windows.  Yet, you want to make sure there are no imperfections that would get in the way of seeing through a window.  Moreover, when you are dealing with a clear window film, which is used mostly for residential and commercial windows, PET’s clarity is vital.  Nothing about a window film should result in a window appearing less than clear.

With regard to strength, PET is perfect for the longevity of a window film product.  Gone are the days of the purple-looking, fading, bubbling, or cracked auto window tinting films of the past.  Today’s window films are high-performing, durable, and are the result of years of research and development.  PET, therefore, is the base material you want to ensure that your window film will last a very long time.

What, Then, Is the Window Film Manufacturing Process?
Step 1 – Melting and Creating Film Sheets

Starting with the PET pellets, those pellets are melted down into a material that can be stretched into sheets. Accordingly, the melted PET is stretched width- and length-wise to create a uniformly sized sheet, usually with the help of a roller.

Step 2 – Adding UV Protection Materials

During the initial stretching process, UV blockers are typically added at this point.  As you may know, blocking out ultraviolet (UV) light is one of the best features of any type of window film, given that a regular glass pane will not keep out UV rays.  It is this step that gives window film the UV protection qualities.

Step 3 – Adding Dyes or Metals

Here is where the process begins to differ depending upon whether you are manufacturing automotive or residential/commercial window film. The performance dictates the process.

For automotive film, the goal is typically to absorb heat.  Windows tinted with window film will often make a car hotter in the sun. Therefore, you want the window tinting film to absorb as much heat as possible to keep it out of the interior of the car.  Dyes are phenomenal at absorbing heat.  Thus, you will generally use a dyed window film for an automotive application.

By contrast, metallized films work in the opposite way.  Metallized films reject heat. You want your windows to reject as much heat as possible for most residential and commercial applications because you want to keep your home or office as energy-efficient as possible.  Therefore, you would normally use metallized films for home and commercial applications.

–   Dyeing

To add dye to a window film, the polyester sheet is simply coated with the liquid dye. Then the treated sheet is cured in a heated oven. The oven-heating process has the effect of impregnating the film with the dye.  The dye color become a permanent part of the window film.  It will not wash off.

–  Metallizing

There are actually three different processes for metallizing a polyester film:  (1) Evaporative Coating; (2) Electron Beam Coating; and (3) Sputtering.

Evaporative coating is the process whereby the metal is heated in a crucible to a temperature so hot that the metal melts into a gas cloud.  The metal-gas is then deposited onto the film and immediately, permanently bonds with it.  Aluminum is typically the metal of choice for evaporative coating because it melts at a lower temperature than other metals.

Electron beam coating is similar to evaporative coating.  The only difference is that the metal is heated with a beam of high-energy electrons, that transform the metal into a gas cloud.

Finally, sputtering is the process by which an electrically charged gas, like argon, bombards the metal, which in turn frees the molecules.  The molecules are then placed upon the film, layered side by side, to result in a very thin, precise coating.  In fact, the coating is so air tight that the water used in the process is unable to evaporate away from the film.  So, the film has a hazy look for two or three weeks during the curing process, until the water finally evaporates away.

Step 4 –  Applying the Scratch-resistant Coating & Adhesive

Specifically for residential window films, a scratch-resistant coating is applied to the side of the film that will face the interior of the home.  It is a fine protective barrier to ensure the film lasts and protects the film from dust and debris.

Adhesive is then added to the side that will, as you might expect, stick to the window.  Usually, pressure-sensitive (glue-like) adhesive is used for car window film, and a clear dry adhesive that activates with water is used for residential and commercial films.

Step 5 – Adding the Adhesive Liner

The final step is to apply a covering to the adhesive to protect it in transit.  Like the liner for band-aids, it is the material you peel away when you are about to apply the window film.
