A film I really like
I knew the basement window was drafty. I just didn't realize how drafty it was.
It's an older aluminum casement window, of the type with two single panes of glass on either side with an air space in between. And both sides can open, making them easier to clean. But the frame around one of the outer panes is coming apart. To get through the winter, I applied a generous bead of clear exterior silicone. It helped a bit.
What really helped was the plastic film I applied to the interior. To apply it, one must first warm the window frame with a hair dryer. I hadn't noticed any major leaks, but when I turned the hair dryer on, I could see a cobweb inside the window moving. Not a good sign. And I'd noticed it was cold around the window.
The whole process of applying the film -- I used a ClimaShield kit from Canadian Tire, which cost about $4 -- takes about half an hour. This is because you have to let the double-side adhesive set on the warmed frame for 20 minutes before hanging the film. And the film is a bit unwieldy. For a more complicated job, I might want an extra set of hands. But I did this one on my own with no problems.
It worked like a charm. No more drafts, and I could immediately notice a temperature difference around the window. I have no doubt that, on this particular window, the film will easily pay for itself this winter (almost on cue, it started to snow just after I finished getting it on).
We'll see how it lasts as the winter progresses, but right now, all indications are that this product is very worthwhile, cost-efficient and a really easy way to conserve energy, save money, and make a house more comfortable. Oh, and in case you're wondering, when my son came in, I asked him to look at the window and he couldn't see the film at all.
