Plasticizing our Windows

In an earlier post, I shared with you how it is possible to afix a plastic barrier over older windows to create an air gap. This provides the window with extra insulation. I wanted to follow up on one window in particular.

It is in our rear bedroom. This window is of the older aluminum frame type, which is crazy efficient at passing heat. Winter heat goes right outdoors, and summer heat comes right INdoors! To make things worse, that room doesn’t get much air flow from the central heating system. It can barely keep up in 40-50 degree weather, and below that, fuggetaboutit.

The double sided tape was applied to the painted texturing along the inside of the window frame. It’s not the best seal, due to the uneven surface, but the tape wouldn’t stick to the metal. I justified the lack of added effort at cleaning the metal frame with this twisted logic – the frame is so darned cold, it needs to be WITHIN the insulating air gap, and not a part of it. That done, I have to admit that I screwed up the plasticizing part of it. The upper edge of the plastic came undone. I rectified this by sticking tape to the floppy edge of the plastic itself, and applied a new plastic strip to cover the gap. Worked just fine.

Results? I’ve slept in that room recently when I needed the services of the therapeutic bed we have in there. The cold coming from that window, previously a tangible flow, is next to nothing. The heat pumped into the room in its typical lazy fashion can now bring the temp up to a cozy level. Thank the Lord for whoever invented this stuff.

Next, we will tackle a few others windows, just as soon as out CHRISTmas decorations come down. If this is new info for you, go to the original post, and watch the vids. They will show you all you need to know. IT really is a better answer than stuffing bubble-wrap in the window opening, or hanging plastic sheets down from the drapery rods.

Something to remember. The hair dryer you use to tighten the plastic will heat up the room a touch – it uses a lot of energy. Don’t be too timid with it, and let it go to work fairly close to the plastic. The sooner it gets the plastic taught, the sooner you can shut down the thing.

We got our film at a thrift shop for a few bucks. If you prefer new, Amazon has some. (The brand we got was over $20 online!) This stuff looks to do the same for less than half that.
