Frequently Asked Questions

What is window film?

Window film is an abrasion-resistant, transparent layer(s) of selective wavelength polyester that is applied to, and trimmed to fit, your existing windows. Most films are applied to the interior surface of a glass window in a home, commercial building, or car. When installed by a certified professional, there is no noticeable change to the color of your glass unless a heavily tinted or highly reflective film has been selected.

Window films vary in color (from clear to silver) and reflectivity (from no reflectivity to high reflectivity). And there is no purpling, bubbling, seal failure, or glass breakage.

By applying window film, you can do the following:

  • Reduce heating and air-conditioning expenses
  • Increase tenant and resident comfort
  • Reduce fabric and furniture fade
  • Reduce glare
  • Increase personal safety from flying glass shards
  • Deter smash and grab crime
  • Create privacy for glass-walled rooms and offices
  • Reduce graffiti abatement expenses
  • Replicate the look of frosted glass or etched patterns with decorative film

Window films are maintenance-free and can be applied to regular and tinted / Low-E glass.

What are the benefits of window film?

Window films have many benefits depending on your choice of film.

Safety films can hold shattered glass in place to offer protection from threats like:

  • Burglary attempts
  • Graffiti
  • Wind-born debris
  • Natural disasters
  • Bomb blasts

Tinted window films, also called solar control films, can do the following:

  • Significantly reduce solar heat gain and temperature inside a building
  • Reduce air conditioning costs
  • Extend life of HVAC systems by reducing maintenance and strain on the system
  • Decrease a building's environmental emissions
  • Increase occupant comfort
  • Reduce glare to improve visibility inside, especially for computer and TV screens
  • Provide daytime privacy
  • Block up to 99% of UV radiation
  • Offer significant fade protection for furniture, carpets, woodwork, and other interior furnishings
  • Improve building aesthetics and accent windows
How do I clean my Window Films?

After thirty (30) days, you may clean window films using normal household cleaning solutions, including ammonia based products: e.g., Windex, and a soft, lint-free cloth or towel. You may also use a squeegee to clean the films. Abrasive products which would scratch or damage the film should not be used.

How long does Window Film last?

Window Films are made to last for many years. The exact length of time depends upon the type of film applied, window orientation, type of glass it is applied to and the particular climate in which it is applied. Most applications last well beyond the warranty length.

What is the warranty for Window Film?

Window Films are warranted to maintain their solar properties without bubbling, peeling, cracking, or crazing. Many films are warranted against discoloration, too. (Those which do not use dyed polyesters). Contact your dealer for factory warranties, as they vary.

Do Window Films cause glass to break?

The application of Window Films will increase the temperature of your sunlit glass which will increase the stress on the glass edges. The quality of those glass edges and several other factors (external shading, interior shading, glass history, type of film, size/shape of glass, indoor/outdoor temperature) all contribute to the potential risk of glass breakage. Our years of experience with applying Window Films to different types of glass enables us to make proper film/glass recommendations and minimize the potential for glass breakage.

How do Security Window Films work?

Security Window Films are designed to make glass shatter-resistant by holding the glass pieces together when broken.

Compared to Sun Control Window Films, Security Window Films are made with thicker polyester and a much thicker, more aggressive adhesive. Security Window Films are unique in the industry; they are built using a special micro-layered polyester technology which increases the films' tear resistance significantly. The impact and tear resistance of these films outperform all other films of similar thickness.

Is Security Window Films hurricane-proof? Bullet-proof? Burglar-proof?

No, Security Window Films are not hurricane-proof, earthquake-proof, bullet-proof, bomb-proof, nor burglar-proof. Again, they are designed to make the window glass more shatter-resistant.

Although, in the event of a natural disaster, these films may have significant safety and security value. They can reduce the risk of injury from flying shards of broken glass, and possibly help prevent debris and water penetration through the window depending on the severity of the storm (and the type of glass, framing system, size and velocity of objects, and more).

Security Window Films were originally developed to address international concerns and needs for improved safety against terrorist acts of bombings. These films can significantly reduce the risk of serious injury from flying shards of glass due to blasts. However, these films are not designed to stop bullets.

Security Window Films are a low profile, high performance measure of security in the battle against 'smash and grab' crime. The tough, shatter-resistant qualities of the film can hold the window glass together even if a brick (or similar object) were actually to pass through the glass. The thief must now make a choice; continue to attack this window, try another window, or move on. Time is short, and often they move on. However, if they are determined to gain entry, they will get in. It is generally recommended that the property have proper alarm systems in addition to Security Window Film.

Do clear window films provide the same benefits as darker films?

Yes ,window film doesn't have to be dark to provide benefits like heat reduction, energy savings and ultraviolet (UV) protection. In fact, some darker films are dyed polyester that simply provide greater privacy. We offer a wide range of window film shades for architectural and automotive applications, giving you options that best suit your needs.

Will my window film bubble or turn purple?

No. Purple, bubbling film is a sign of a very low-grade window film whose mounting adhesive and dye components have broken down. The films used by ASI are warranted against this, they use more stable and advanced dye chemistries and/or permanent metal layers that do not discolor over time.

How Much Do The Films Cost?

The cost of automotive, decorative, solar or security films will vary with the thickness, type of material, and size of the area to be covered. ASI will provide you with an estimate at no charge. Please call for an appointment. 1-800-516-0105

How is window film installed?

Window films are installed by professional window film installers. The installation process starts with the installer thoroughly cleaning your windows to remove even the smallest pieces of dirt. A piece of film is cut roughly to the size of your window, its release liner is removed, and an application solution is sprayed on the film's adhesive to activate it. The application solution is also sprayed on the window. Then the film is installed on the glass, and the installer squeegees all the application solution out from between the glass and film. The installer will also do some final edge trimming to ensure the film fits perfectly.

How long does the film take to fully cure?

When the dealer squeegees out the application solution during installation, it is nearly impossible to get every drop of solution out. Thus there is a drying time (cure time) for the film, during which the remaining application solution between the film and glass evaporates. During this time, the film is still performing to its full solar control and safety capabilities. However it is common to see bubbles, haze, streaks, and other visual defects in the film as it cures. This is completely normal, and these will disappear as the film dries out.

The amount of time for the film to fully cure can vary drastically. If it is a dark solar control film on a south or west facing window in a hot climate in summer, the film can be completely cured within a few days. However if it is a heavy gauge safety film installed on a north facing window in wintertime, it's not uncommon for the curing process to last over a month. Remember though that the film will perform as designed during the drying time, the bubbles and streaks are purely cosmetic.

Exterior vs Interior?

All films except for extremely rare circumstances are applied on the interior surface of the glass. Exterior films are applied for three reasons:

  • If for any reason a window is not accessible from the inside, an exterior window film would then be your only option unless the glass is pulled out from the frame
  • You are applying graffiti film. Graffiti films are thick clear films applied on the exterior surface of glass, mirrors and even elevator doors designed to protect the surface from accidental and (or) malicious behavior. This saves you from having to replace the damaged surface
  • If your glass is laminated. Most films cannot be applied to the interior side of laminated glass although exterior films can be used
