Low e i simply an applied metal layer on glass.

Most often found on surfaces 2 or 3

2 surface in southern regions as to keep heat out.

3 surface in colder climates to limit heat loss. Like a low e film that is applied to the inside of glass which would be surface 4 on an IGU.

Use a lighter to check which surface and can often determine type of coating by color of flame. Can be on surface 4 too.

Low e does absorb more heat than clear glass. Much like a metal film. But you wouldnt necessarily lose all benefits of low e if tinted.

If you tinted a window with low e on surface 2. The low e coating would already be "emmiting" the heat back outward so theoretically you have benefited from low e before solar contact is made with the tint on surface 4. But you are also insulating the inside pane with a film to slow convective heat transfer. From whatever heat is absorbed by low e coating.

Are you tinting single pane windows or applying film directly onto the low E coated surface

Hey Awesome,

It is not so much that the glass Hard coat LowE would be distroyed, it is more so the fact that it just many types of LowE coatings use the surface of the coating to reach it's performance peak. Adding an aftermarket coating of any kind (Other than a higher performing LowE film) will result in a higher rate of heat transfer, and in a way, ruin the performance of that glass. There is also the issue of if the film ever required removal, doing that without damaging the coating can be almost impossible.

 

Finding out which surface the coating is on and the type of glass is crucial. If your not completely sure.. Let it go..

 

BTW... Just a hint... Please don't try and take on Tom when it comes to installation knowledge..

Let's just say that he is at the top of the tinting tree so to speak. I know your father has been around a long time, but Tom is at a whole nother level.

 

Welcome to the forum mate! I'm lovin' the shameless plugs that you are giving me :lol

Yeah, Tom knows his stuff ...

 

And yes, putting tint on the lowE coating negates the lowE capabilities; however, this only applies to single pane lowE.

 

There's a trick using a cigarette lighter. Flick the Bic lighter and look for the color variation in one of the flame reflections. The color tells you type of metal used for the coating and the reflection that is colored tells you which surface the coating is on.

      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?

      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!
