IF THIS GETS TAKEN IN THE WRONG DIRECTION.. I WILL ASK THAT THE WHOLE THREAD BE DELETED   :evileye 

 

I was talking with a rep recently, and one thing he said made an eyebrow raise :?  I would like to know and discuss how much truth there is in this statement.  This was brought up when I said something about looking at different films and all the performance numbers and specs on different films.  

 

All films, no matter who makes them, perform the same.  If it's the same VLT of dyed, hp, ceramic, IR, etc.; performance is the same due to the physics and construction of window film.  A 20% mirror from this company is going to perform the same as a 20% mirror from that company.  A 35% dyed will perform the same as 35% dyed no matter who is making it. 

 

 

 

I understand what he is trying to say, If this is true, it would seem to me that the only thing we should be looking at as purchasers of film on the shop side(not customer side) would be:

Color, Handling(shrinking), Longevity and performance of adhesives, Scratch coat quality, Optical clarity  and PRICE OF FILM.  

 

Thoughts on this please.  Thank you.

I would have replied back to him asking why the name brand mac-n-cheese tastes better than the generics. Lol

Hello Bham,

 

The statement is incorrect.  Please do the following.

 

#1    Call up this rep

#2    Ask him/her the definition of Luminous Efficacy

#3    Post the answer on this thread

 

The only instance where this statement would be true would be if the 2 films being compared were made with exact the same components and processes, in which case the LE would be equal.

All films do the same thing: They filter em energy at various wavelengths in 3 basic regions "UV", "Visible Light, and "IR"

 

To what amount they filter depends on what the film is designed to do and the materials used therein.

 

If the components are similar then it stands to reason that the performance will be similar. For example something basic like a dyed film would probably support that theory. But take a spectral select film and pair it up against a similar vlt product and you will find a big difference in performance due to what's called the "LE" or luminous efficacy.

 

So short answer... "No" they do not all perform the same.

LE = VLT/SC.  This is the holy grail of window film comparative performance. 

 

Once you combine this with a thorough understanding of components, construction methodology and longitudinal durability, you truly get the "big picture" of how Film A compares to Film B.

@  Howard at EWF....  email sent to him,  awaiting response.  

 

So from a purchaser's standpoint,  I'm looking at multiple dyed films or ceramic films from different companies, and all of the performance numbers are about the same,,  where does that take me??

Hi Bham,

 

I did not receive an email from you.  Please send to howard@buytint.com

 

Note:  I have a conference call coming up at 2PM Eastern.

 

Thanks,

 

Howard

      Air80 vs Stratos70 Windshield

      Since there is no limit of darkness on the top strip, I have wanted to tint it. But I would go very dark, to help with sun glare in the evening.

      Air80 vs Stratos70 Windshield

      Yeah that’s a very fair point to a degree I’m probably overthinking it. I don’t see really significant glare reduction until you get into much darker tint. Like you I think visibility for me is more important living in the country. I’ll probably see what the specs list the differences between 70% and 80% and then double check with the tinter as to what they recommend. Likely will end up with 70% with a strip along the top. Air80 seems to be much more popular, not sure if it’s due to performance or the difference in cost being so much more for the stratos. thank you

      Process

      Hey guys - so I work for a vinyl graphics company that is adding window tinting to their repertoire and I had a question about your guys' ideal process. I have my plotter set up and my window tinting software ready to go, but I am completely ignorant about the way that tint installers prefer that things be cut. Currently, I will plot/weed the tint and cut the backing away as much as I dare before handing it over to the installer. I was thinking that the installer would prefer the tint to be cut to shape which I believe I can achieve with the perf cut on my plotter. Is that the typical process or should I not be worried so much about it being cut to exact shape?

      Air80 vs Stratos70 Windshield

      Im in TX, plenty of of what you mentioned. While I do sit higher in an SUV, glare reduction is not improved much at all with what I have. My 80% is almost clear, not dark at all. With all tint, it adds a bit of reflectivity from the outside, which I notice makes it slightly harder to see from the outside looking in, in the form of a glare not darkness. At the end of the day, it's not permanent, it's only money!

      Boat window tinting tips

      The answer is to not heat that area too much so that you leave some slack in the film for when you get it to the inside. Also cut your pattern a little large so that you can trim a thread off the edges after shrinking to not have a furled edge. After you do a few of those you'll figure out how much to leave/trim to not have any light gaps. Also I'll leave a hardcard wrapped in a microfiber in the bottom overnight to collect water and keep pressure on the film while it dries. Sometimes you can take the top rail off the glass if the jackwagon boat builder didn't put too much pressure on the glass package when it was installed. If you pull the rail off of a tight package it's a pita to get back on, looking like it could crack the whole time. Congrats on getting it done. I've seen plenty that couldn't, which is why I price them like I do.

      Boat window tinting tips

      Thx everyone for the tips the install went fine, however i did run into a new problem on the main curve of the glass from thr outside the tint would lay flat on the big curve but when applying it seemed like there was too much tension and it would not stay down i ended up heating it up and flattening down but some of that area got overheated and warped a little, if you know how to tackle this problem please help me thank you!
