This web site is huge, how do I know where to go and how to get around?
This site is large, over 200 pages with more being added regularly. While it is large, it is relatively simple. There are 4 primary parts. First there are descriptions of our products from a dealers point of view (i.e. why carry a film). Second there are thorough step by step installation instructions for Auto, Flat and Security. Third, there are education sections for solar energy, glass, film manufacturing and specific safety film topics. Lastly there is a marketing section which has ideas that may help you grow your business. The links on the left expand to show you all the pages underneath each heading. If you have questions please post them in our discussion board. You can also type in a keyword in the Search field on the upper-left.

Why is there only an online store for dealers in the US and EU?
Simply, since we do the distributing here we could do what we want and manage it. Both of these systems (US and EU) tie right into our accounting system so dealers can check purchases, place orders, see account history, and take advantage of web specials. Sadly, our other areas will still have to call their orders in by phone for now.

What is 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.

Why are the installation instructions for automotive broken up into sections?
The auto install process has several distinct processes and we think it is a good idea to think of them separately. Cleaning the window needs to be done right and thoroughly. It is so important we think it should be talked about and practiced separately from cutting a pattern or hanging the film. Heat shrinking is its own beast and it needs to be learned and mastered separately. The same goes for pattern cutting etc. etc. We know that some of you prefer seeing it all in one but if you concentrate on one at a time you will learn them better.

What if I think your installation methods are not the best techniques?
We do not think we are all that smart. If you have a better way we want to hear it. Please post it on the discussion board and if it is good we will add it to the instructional pages. We will even give you credit for the idea.

Can I apply auto film on a home or building?
NO! The reason is simple; it just doesn’t 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 doesn’t 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 don’t heat up as much. If you can figure out how to get a house to drive down the road you can consider auto film for it but until then take a look at these pages Click here to see the different way heat is transferred (radiation, convection, and conduction). Cars use convection to remove heat and building use reflection of radiation.

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% reflection to be put on a car but anything over 15% usually is considered too reflective.

How do I remove old film?

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.
1. There must be more light on the side you want to see and less light on the side you are looking from.
2. There must be a mirrored surface on the mirror side and less reflectivity on the “view from” side.
3. Try Solar Silver 20 on the outside and 20 charcoal on the inside. Alternately flat glass films such as MG10 with the silver side facing the light are pretty good right out of the box. For more privacy, cover the inside with a layer of CH35. Film on top of films is not warranted but if it is inside a building who cares. No sun, no problem. Any darker and no one will see anything.
4. See #1 again. It is the most important.

Can I put a link to JWF’s web site 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 you are somehow authorized by us. Other than that you may link to our site as a reference for more information on our products.
