Can you explain the difference between Dry Adhesive (DA) and Pressure Sensitive (PS)?
The simple answer is that Pressure Sensitive is sticky and dry adhesive is not. The actual differences are a little more complicated. Click Here to go to the “Adhesives” page for a full description. Dry adhesive is clearer, stronger and easier to “one man” install but it takes several days to really bond to the glass. PS or pressure sensitive sticks quickly but remains soft for its entire life. Soft is good in security films to add a little “give” and on curved auto windows when it must stick right now but DA will outlast PS 2 to 1.
What if I have an alternative installation technique?
This industry is very fast moving when it comes to innovation in both film production and installation, we know there is always room for improvement. If you feel you have a better way, we want to hear it. Email your technique to email@example.com, if we think it's good we will add it to our instructional pages, giving you credit for the idea. If you could include pictures to help with your explanation that would be even better.
Can I apply auto film on a home or building?
NO! The reason is simple; it just does not work and can actually make the inside hotter than before. It has to do with the difference in how auto films work versus how flat glass films work. Auto films absorb energy and as the car drives down the road, the wind pulls heat from the glass.
If the car does not move the windows get very hot and become heat radiators heating the inside of the building. Flat glass films that reflect energy keep the energy form being absorbed (actually reduces it) and therefore the windows do not heat up as much.
Can I apply flat glass film on a car?
Unfortunately, the answer is NO again. This time it is because flat glass films are generally too reflective. Auto laws generally require film to be below 20% reflectivity to be legally installed on a vehicle but anything over 15% usually is considered too reflective.
How do I make a "one-way" mirror effect?
Nothing is a perfect one way system but a pretty good one can be created if you keep the following in mind:
There must be more light on the side you want to see and less light on the side you are looking from.
There must be a mirrored surface on the mirror side and less reflectivity on the “view from” side.
Try Solar Silver 20 on the outside and darker non-reflective film on the inside. Alternately flat glass films such as NS15 or NS 25 are pretty good right out of the box.
For more privacy, cover the inside with a layer of RN35. Film on top of films is not warranted but if it is an interior office window who cares. No sun, no problem. Any darker and no one will see anything.
See #1 again. It is the most important.
Can I put a link to the Johnson Window Films website on my site?
Yes, but we have a few rules. Most importantly, you may not pull (or copy) parts of our site into your site. This is a copyright infringement of which we are very touchy and we will take steps to have you remove it. If you refuse, we will prosecute. Second, you may not infer that our site is yours or that we somehow authorize you. Other than that, you may link to our site as a reference for more information.
What are the benefits of your Anti-Graffiti window film over the competition?
Our Defendor products are both 2 ply products, this leads to positive results in performance, installation and when necessary, removal. The layer of film closest to the hard coat protects the underlying layer, this also allowed for the introduction of an additional UV inhibitor within the laminating adhesive, offering even more protection to the glass bonding layer. The introduction of the UV inhibitor stops the underlying layer from breaking down, making eventual removal easier.
Can I install window film on plastic surface?
Once lexan, polycarbonate or Plexiglas is exposed to any kind of heat they slowly release chemicals and absorbed moisture from the original manufacturing process referred to as out-gassing. The installation of window film traps the gas, which causes bubbles in the adhesive between the plastic and the window film. Johnson has three products that are made with a specially formulated adhesive to allow the gases to dissipate after installation.

Since the major cause of interior fading is UV light and window film rejects 99% of UV then it stops interior fading by 99%
This is not true there are 4 causes of fading, as explained by the AIMCAL is 40% UV Light, 25% Visible Light, 25% Heat and 10% misc. The reduction in UV light of 99% from the installation of window film results in 39.6% reduction in this single cause of fading. Therefore window films slows but does not stop all interior fadingt.
