Reusable Plastic Window Frames

Posted November 06, 2007 12:52 PM by frankd20

It's getting cold where I live and that means time to think about insulation and how to keep your house warm. One common area of heat loss is through windows. Last year I had an energy audit done on my house to identify ways I could reduce my energy use. Although my windows were identified as something that could be improved, I didn't have a ton of money budgeted. I was told my money would be better spent on other improvements so I put plastic on my windows to help increase their effectiveness. As a cheap way to help insulate, or for people who rent and can't make changes to the building this is a good alternative to replacing the windows.

Every year I spend a few hours putting plastic on my windows and then pulling it off when it gets warm. I find that the plastic helps, but it feels quite cold to the touch. In addition, sometimes when the wind blows the plastic moves; I decided there must be a better way.

I decided to make a simple wood frame that would fit in my window that I could put the plastic on, so I could reuse it. Once I started making these frames I also realized I could put plastic on both sides so I'd have an air gap between them for better insulation.

The design is really simple. All you need is 1x2 inch wood strapping that costs about fifty cents for an eight foot length, window plastic, tape, and a few screws. Each window frame ends up costing only a few dollars at most and are reusable each year.

I used these frames last year and did notice that the plastic didn't feel nearly as cold and I didn't feel any drafts from the windows. At the end of the year taking the frames out was a piece of cake. I just recently put them back in and it was much easier than taping the plastic up.

So far a simple project that has saved me a few bucks on heating costs. I will add one caveat to this project, my wood frames insert on the inner side of the window. Old windows can also leak where the frame meets the wall. If you have this problem then you should first seal those leaks as my frames will do nothing there.

This is not a new idea, the Scandinavians were doing this before the advent of double or triple glazing. The Scandinavians used glass instead of plastic, but my father in law in Norway used plexiglass in the 1950s and 1960s. Spencer.

I find a thrown chair goes through the plastic just as easily as it does the window on the other side...in an emergency, I'm not concerned about removing things, I'm concerned about getting out ASAP.. :)

But your point is sound. Generally not a good practice to seal yourself in too tightly..

On the same note, for the last few years years I've been using automotive tinting film on the inside of most of my house's south- and west-facing windows (up here in the N. Hemisphere) during the summer - we find it keeps the interior of the house much cooler as it appears to reflect not only light but a certain amount of radiated heat as well. I read somewhere that this was not recommended for double-pane or other 'insulated' windows, but I've found no ill effects yet, after three summers of it. Anyone else ever try this?

My problem would be where to store the darn things when not in use.

Still, it's a good idea to use on the fixed leaves of my double patio doors...huge area of cold glass. I shall use it as an 'armchair project' for now .

The picture of your house didn't look like one of Sir Fred's wonderfool flat-roofed efforts - but I suppose your roof timbers are too closely spaced to allow adequate access. I used to have a wall-to-wall rack for such things in the garage (in the excess height above my car), but I suppose you are in one of Harlow's garage-free zones? Back to the low-slung garden storage shed, then, or does the Wendy house fill the entire pocket handkerchief?

Hi Del.

My father in law in Norway used to store his in the loft? He was also one of the first persons to use triple glazing!

This was acomplished by fixing plexiglass to both the incide and the outside of the removable frames. He was doing this way back in 1966 when I first moved to Norway!

You must understand that the Scandinavians are way ahead of us when it comes to insulating their houses, they have too because of their extreme winter temperatures which can last for many months.

Spencer.
