West facing window issue

I put solar tint from Lowes on my west facing windows.

Made a huge difference.

I have tinted home windows before. And now technology has become so much better. Wednesday I am having tint put on my front door. It's insulated and double pane but not as cool as my Low E windows in the same room. The tint they are installing is 70% VLT so virtually clear and block out TSER of 51%


Total Solar Energy Rejected is the percentage of the total solar energy that is rejected. TSER includes all three: visible light, infrared and ultraviolet. The higher the percentage, the higher the percentage of solar energy deflected. Most window film/tinting shops use Infrared Rejection (IRR) as a guide to the level of heat rejection but IRR only covers 1/3 of TSER. Internationally, TSER is used as a guide as it is a more accurate way of measuring heat rejection as it includes all three (visible light, infrared and ultraviolet).

Awesome. This is what I am going to try. Thanks for the info

had someone install 3M Prestige-60 film on my windows. It’s awesome. Definitely reduced heat and brightness. Mostly I was just tired of how bright it was and it’s really helped. Sort of expensive, but it’s not really tinted, so you can do part of the house and all your windows still match.

Same. Love it. Not cheap though

Mine was prestige 40, not sure what the difference is. I opted for night vision 3m 25 for some windows. Same heat reduction and blocks more light, a good bit cheaper than prestige. Prestige is meant to still maintain outdoor view entirely while still getting heat reduction and some glare reduction.

Anyone knows who does this in BR ?

You use a razor blade. But it’s a nightmare if it’s a cheap material because it will drag and make the edges jagged. A lot of installers will just cut the white strip border out along the edge of the windows.

Fair warning that many windows come with a 10 year manufacturer warranty and applying a film to the window will void the warranty.

I had looked into this for my house, which already has lowE windows (these are double pane windows with a transparent metal coating on the inner surface of one pane). I've been told that adding solar film to lowE windows is not as effective as other window types since the lowE surface coating and double pane insulation already protect you against a significant amount of heat. Ultimately decided against it. Guys in this thread that got the 3M prestige film and found it helped, was it applied to lowE windows?
