Weatherization – Window Film vs Window Replacement

Very interesting article! I never thought that tinting the windows of a house would make such a difference. Everyone seems to want new AC units or central air, but who knew that simply tinting your windows will actually keep the heat out from the start! Makes sense, just like in auto applications, but on a much larger scale.

Most people think of tinting of their car or SUV. Tinting the windows of their home is nothing new. Glass tinting of some sort or another has been around since 1946. Some think that glass tinting started in the 1300′s with stained glass. In any event, glass tinting can reduce solar absorption by as much as 85% depending on what type of glass you have. Thermal windows or dual pane windows still emit a lot of solar energy and can reduce solar absorption by as much as 50%. A few words of caution on dual panes windows: dark films can lead to fractures and /or seal failures, so you’re limited as to which types of film you can use. Silver reflective films are the best with these windows for the most reduction of heat. The other matter is dual pane glass with argon gas inserted into the “dead air” leads to the best reduction of heat, so window tinting is not advised. If you have a glare problem here, some other kind of glare reduction is more appropriate like interior blinds or shades.
