another good question V....I would guess it is the type of "ceramic" that is used. Just like V-kool is more because of the type of metal used....

Now my curiosity is burning. It appears to be a similar situation as V-kool, less reflectivity, lighter film, and higher performance. It is 67% vlt why is the SA more than the Geo 40?

Solar Absorption is lower on the 3mm glass for it.....glass factors in. I don't have the numbers in front of me, but they happily gave them to me.

Yeah you're right glass does factor in.

IRis 70 6mm clear

SA=54%

Geo 40 3mm clear

SA=50%

But the IRis would be equal at best if they were both on 3mm.

When I asked them about performance on different types of glass they stated that the IRs70 performs best on single pane glass and the Geo lines performs better on dual pane. But there was only a 5% difference in the performance numbers (heat rejection) when used on dual pane. All I know is that the customer I installed the IRs70 on her sunroom noticed a huge difference from before in regards to heat in there. So it must be doing something, I mean she even told me to keep her phne number handy in case a future potential customer needed a reference.

It interests me. #'s are better than PR70. So if they are all ceramic then why is one recommended for single pane and the others for IG? :dunno

you know I dont get into much technical data. but arent we not suppose to install window films that absorb more that 50% on dual pane? I think that is the reason. back in december I had a customer who wanted 70IRIS on some dual pane skylights. they recommended I go with a 50% to keep the heat absorbtion down!

I havent been able to sell this stuff as I wanted to, but im hoping I do.

That is what I thought but Geoshield is willing to put in writing to warranty it. I have asked a couple times in regards to using the IRs70 on dual pane non tempered and they were more than willing to sign off on it...Thats all that matters.

      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!
