Weatherization – Window Film vs Window Replacement

It is always good to see that other blogs, especially one as highly regarded as Treehugger, agree with your assessments.  In a previous article titled, New AC Unit vs Window Tint, we determined that window tint is much more affordable an better ROI (return on investment) than both a replacement AC or replacement windows.

At more than $5k for a new central AC unit or over $250 per replacement window, window film easily becomes the most economical choice at $2.25 per square feet for professional DIY window film.

Treehugger reports that National Trust for Historical Preservation states:

… a complete myth that replacement windows will save you money. In fact, they go so far as to say that the payback period for replacement windows is probably twice as long as the life of the window.

The preservation society offers more tips:

    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.

    Thanks for talking about this! Windows are such huge energy hogs and so often people only talk about cfl lightbulbs and turning off power strips.

    Window film can be tricky to get right, but it is incredibly easy to install insulated cellular window shades! We offer honeycomb shades with a 10 year warranty, which will start saving you money instantly and are made in the USA. I’ve had many customers use film and still felt the need to purchase our shades. They help with noise reduction as well as keeping a space more comfortable in the summer and winter.

    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.
