Like everyone, I am trying to save on energy bills. I bought Gila "low e" window film and did my son's room first. There are three rooms on that side of the house with the exact same windows, all receiving the same sunlight. After installing the film, his windows are remarkably hooter to the touch on the inside! I talked to a manager at Lowes (where I bought the film) and he assured me this was how it is supposed to be. Is this true? Also, I have been told by several people in the window industry that tinting the windows with the low e solar - gard will help in the winter also. Do you know and can you help me with this? I know I must do the entire house to see the difference in my bills. Am I wasting my time and money (neither of which comes easily anymore : ). Thanks

You might see 5-15% reduction in cooling costs (depending on compass direction, film type and geo-positioning in Florida. However, LowE in Florida :thumb Can't possibly use the heat enough there to impact electric costs. :thumb

Glass is hotter because the sun's energy is stopped at the glass. The real test to see how well it works is to measure the temp of the floor or carpet where the sun strikes before and after tint is applied. It is best to measure floor surface temp a minimum 20 minutes after film has been put in place. :thumb

Basically window film absorbs a portion of the heat and reflects some of the heat. How much of one or the other depends on the film. Plain clear windows don't abosorb any heat so they will not feel warm to the touch(normally). So in short if you put something darker than clear on a window it will feel warmer because it is absorbing heat. :thumb

:thumb Clear glass absorbs 9%.

The film spoke of above might absorb 40% (glass and film), give or take. :thumb

      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.

      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!
