Gila Titanium Heat Control Window Film HRT361 Product Overview

HRT361 is one Gila window films that you can add to any window to reduce the radiant energy transfer i.e. it reflects heat  (infrared) no matter whether it is come from the inside or outside.  HRT361 is said to “Reject upto 72% of Suns Heat” and block 97% of UV rays. It comes in a roll of either 36 in. x 180 in. (15 feet) or 36 in.  x 1200 in. (100 feet) or 48 in. x 180 in or 48 in. 1200 in.  For the typical DIY it is probably better to buy the 15 feet roll even if you end up needing to by several because it is easier to handle and you are probably not going to do all the windows at once.

Installation of the HRT361 window film

The basic idea is you cut a section to fit a pane on the window; remove the protective film from the reflective film; spray both the film and the glass with the application spray and apply; then workout the fluid with a squeegee.

My experience Installing Gila window film.

  1. Before you begin you should was the windows a couple of times until they are clean on both the inside an outside.  While the outside is not needed for the application of the film it helps you see if there is any dirt on the inside.  In my case the windows were so dirt that the dirt seem to be fused to the glass.  I washed them with Windex three or four times and could still see dirt but nothing was come off so I used some Scrubbing Bubble which go the dirt off but then I had to clean them again with Windex.  You should also get a window scrapper to get any paint off.
  2. You are going to want the follow:
    1. A table or a flat surface to layout and cut the film on.  Ideally it should be 36 in or more wide and a maybe 6 inches long than he window pane is high.
    2. You are going want a tape measure, squeegee, scissors, a marker,  straight edge (yard stick is good), scotch tape and of course the Gila film and Application kit.
  3. Next you measure the glass area of you window.  They suggest adding a inch top to bottom and left to right.
  4. Then you want to roll out a section of film, measure it and with the straight edge as a guide market with you marker.
  5. Now you can cut it with your scissors.  In my case is had partitioned windows so I measured out 29 inches cut that section then marked 14 inches in from both sides and cut that. I did this so I would have factory edges on both the left and right pieces.
  6. Next you are going need to remove the protective film from the reflective film. To do this take a piece of scotch tape put it on top side of the film, then pull gently and he to films should separate.
  7. Now spay the Application Solution from the Application Kit on the film and window.  Then take the film over to the window and set in place.  It will cling to the window. Work out in large bubbles by hand then spay the application solution on it and use the squeegee to set it in place.
  8. Now get the trimming tool from the kit and trim the excess film away.
  9. Finally use the edging tool which I think they refer to as a squeegee and wrap it with the lint free cloth and work out any remaining fluid.

And that is it.

Here is a video of me installing it on my old window.

The Gila Heat Control window film is easy to install and had a noticeable effect blocking the heat coming in the window. It does have a silver/gray tint to it so you may not want it on all your windows.  It is like having sun glass on your windows.  At around $30  for 15 feet ,about 3 windows, plus about $9 for that application kit which I think would be good for a several of the 15 foot rolls, it is not too expensive.  It is certainly cheaper than new windows or Low E storm windows.  If you have really old windows you will probably want to get new windows at some point but this could help you save some money in the meantime.  Most information I have read have indicate a payback in 2 to 3 year compared to 25 to 30 for new windows.

  1. Amazing review buddy. I’m not a big fan of window film, but after reading your review it looks like I’m totally missing out! I like how you mentioned the steps in which we should follow. This is helpful indeed, ESPECIALLY for newbies like me who doesn’t know much about this sort of stuff.

    You are doing a good thing here buddy, so good job and keep up the good work 🙂

  2. I have bought this before from Home Depot and followed the steps you have outlined. Problem is that on every window I have an issue….it still ends up not staying on the windows. I am a great DIY person, so I am not ill equipped to do something like this. So I cannot figure out what I am doing wrong. I cleaned the windows as well. Any ideas?

    • Thanks for the comment. I had actually been wondered how hard it would be to remove so I try but did not have much luck. Here it the thing, there are two versions of the this film the Peel and Cling and glue. The Peel and Cling uses static charge difference of the plastic and the glass to hold it in place. I can image this does not hold very strongly. The glue version which is what I used has glue on the film and you can actually feel a slight tackiness when you peel the protect layer off. The Film Application Solution which I think is just soapy water softens the glue so it sticks to the glass then bonds to it as the water works its way out. I would suspect you got the Peel and Cling version. I noticed at Home Depot web site people commenting that the Peel and Cling starts peeling off almost immediately.

  3. Hmmm… very cool product. Just one question, how does this affect heating from the sun during the winter time? It seems this film is meant to be permanent, so I can’t just take it on and off with the change of seasons. I’m a big fan of keeping the home cool during the summer, but also love the sunlight and resultant heat in the winter time as well.

    • Thanks for the comment. I feel the same way, which is why I put it on the north and some of the east and west facing windows but not the south facing ones. I found that the angle of the sun in the summer is high enough that the direct sun light doesn’t come in too much and white blinds are fine. The winter angle sends the light about 8 or 9 feet into the room. So I get my sun light from the south and focus on minimizing heat transfer on the other sides.

  4. I’ve thought about putting a tinted film on the windows at the front of my house for quite a while. Never actually thought I could buy it and do it myself. I’d really prefer a tint that you cannot see inside through the window when outside, but you can still see through the window from inside the house. Is this something that is available to purchase?

    • Andrew, thank you for the comment. What you are describing is usually referred referred to as a privacy window film. Gila and several other manufactures have them. The Heat control film does have a mirror type look from the outside similar but not as pronounce as the privacy film. The one caveat is that all of them including the privacy film are see through at night. So in the day from the outside it is a mirror but at night if the light is on inside people can see in so you would want blinds.
