3M Sun Control Window Films are designed to reduce the amount of solar heat transmission through window glass by increasing the solar reflection (not necessarily visible reflection) and solar absorption through the glass.
Typical colored or dyed films work primarily through increased absorption. The color absorbs the solar energy at the glass, thus reducing the direct transmission into the room. These films are not as effective as reflective films for reducing heat.
Reflective films are films that have been precision coated with metals. These metallized films are designed to increase the solar energy reflection of the glass. 3M Reflective Films range from moderate to excellent in solar performance (heat gain reduction).
All 3M Sun Control Window Films are made to be transparent and optically clear. The ultraviolet protection in the adhesive system is there to protect the adhesive, the metals, the polyester film, and the abrasion resistant coating from UV degradation. This UV protection will also help protect home and office furnishings.
Most 3M Sun Control Window Films are protected with our patented abrasion resistant coating that provides long-term durability and maintained appearance.
Simple paybacks will vary depending upon the amount of sunlit glass exposure, the type of film, the type of glass, cost of fuel, cost of application, and other variables. However, we have seen paybacks often range in the 2-5 year period, with some reported to be even less than 6 months. Please contact 3M Sales Engineer to analyze the potential energy savings in your commercial property.
3M Sun Control Films are professionally applied by skilled, well-trained authorized 3M Applicators. Most of our films are designed to be applied to the inside of your glass.
The first step is to prepare the window area for the application; placing drop cloths on the floor protecting and/or moving furniture where necessary.
Next, the window glass is cleaned using simple cleaning solutions (often water and ammonia) and razor blade scrapers. Then the film is sprayed with a slip solution (detergent and water) for proper positioning, and applied to the window glass. Using a professional grade squeegee and following proper techniques, the application is completed by removing excess water, trimming the edges, and a final squeegee technique to dry the edges.
We suggest allowing thirty days for the film to fully dry and cure. During this curing process, it is normal to have small water bubbles and/or a hazy appearance. These will disappear as the film dries; depending upon the film type and weather conditions, drying may take as much as 30 (or even 45) days, or as little as a few days. Once dried, 3M Sun Control Films will look great and perform for many years to come.
No, 3M Window Films require professional application; our authorized 3M Window Film Dealer/Applicators are thoroughly trained and experienced in performing high quality work. In this way, our customers will enjoy the benefits of 3M Sun Control Window Films and have the comfort of the 3M warranty.
After thirty (30) days, you may clean 3M 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.
3M Window Films are warranted to maintain their solar properties without bubbling, peeling, cracking, or crazing. Should the product proved to be defective, 3M and the 3M authorized applicator will replace the film and provide the reapplication labor free of charge.
No, 3M Sun Control Window Films do not cause seal failure. We've been applying 3M Sun Control Window Films to insulated windows for over 40 years with several millions of square feet of film applied to date.
When recommended films are applied to the inside pane of an insulated glass unit, there will be some absorption (except with clear safety films) of the sun's energy, which will increase the temperature of the glass pane. Some of this heat will transmit to the airspace, slightly raising the airspace temperature. However, even a 20 F degree increase (unusual for most films) will result in a less than 3% change in air pressure, whereas properly made units are designed and tested to withstand 22% changes in air pressure.
Risk of seal failure is greatly determined by the quality of workmanship and the quality of the materials that go into building the insulated glass units. The best guard against seal failure is to purchase well-made units from reputable window manufacturers that have solid experience and histories with insulated units.
Nothing completely stops fading. 3M Films are designed to help reduce the major causes of fading (ultra violet light, visible light, and solar heat), thus prolonging the life of your furnishings, perhaps as much as two to five times.
Keep in mind the article(s) to be protected; if they have a typical life of five (5) years then they may last ten (10) years to much longer depending on the performance of the film selected. However, if the typical life is only 2-3 weeks, then the expectation should be expressed in terms of months.
As a general rule of thumb, ultra violet (UV) is approximately 40% of the cause, visible light is about 25%, and heat about 25%. The remaining 10% can be attributed to humidity, pollutants, interior lights, dye stability, and more.
No, the ultra violet (UV) protection that we use in our proprietary adhesive system is indefinite. It does not loose its effectiveness over time. In fact, we tested an actual glass sample from The Dumbarton House, Washington,DC. This was a ten (10) year old application and the ultra violet transmission still measures <1%!
3M Safety and Security Window Films are designed to make glass shatter-resistant by holding the glass pieces together when broken.
Compared to 3M Sun Control films, 3M Safety & Security Window Films are made with thicker polyester and a much thicker, more aggressive adhesive, 3M Safety & Security Ultra Films are unique in the industry; they are built using a special micro-layered polyester technology which increases the films' tear resistance significantly. Pound for pound, the impact and tear resistance of Safety & Security Ultra films outperform all other films of similar thickness.
No, 3M Safety & Security Ultra 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.
In the event of a windstorm, 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).
In an earthquake, these films can reduce the risk of serious injury from flying shards of broken glass, and possible prevent glass from falling out of a home or building. Again, much may depend upon the severity of the quake (and the type of glass, framing system, and more, too).
Bullets: these films are not designed to stop bullets.
3M Safety & Security Films were originally developed to address international concerns and needs for improved safety and security against terrorist acts of bombings. These films can significantly reduce the risk of serious injury from flying shards of glass due to blasts, however, much depends upon the severity of the blast and the proximity of the window glass to the blast (and glass type, framing system, and more too).
3M Safety & Security Ultra 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 Safety & Security Ultra Window Film.
This is difficult to answer with any degree of certainty because it is difficult to test for this. Window glass varies in strength from piece to piece, and lot to lot. So, if a 3M Safety & Security protected window were impacted, yet, failed to break, it would be difficult to determine if the glass alone, the film alone, or the film and glass together resisted the breakage.
When glass breaks, 3M Safety & Security Ultra Film demonstrates it's best performance!
