I had heard of this trick to save energy before, but had never actually gotten around to trying it. While most of the windows in my old Victorian era home have been replaced, with more energy efficient double pane windows, there are six windows in the house with the original old wooden single pane windows. Even with storm windows on them, they still cause a good deal of heat loss, and as a single mom, I just don’t have the budget for replacements.
One thing most bloggers tend to have is a lot of stray packing supplies, so this was a no cost project for me. The wrap I had on hand was the style with the bigger bubbles (about the diameter of a quarter). This seemed like it would be a better choice anyway, as it will trap more air, thus should insulate better than the wrap with small bubbles. The depth of the bubbles is similar to the pocket of air between the panes of my energy efficient windows.
Applying Bubble Wrap to Windows
The bubble wrap was very easy to install and only took a few minutes.
All you need is a spray bottle of water, bubble wrap, scissors and possibly packing tape.
1. Spray a mist of water over the inside of clean window.
2. Apply a sheet of bubble wrap squishy side to glass. Trim off excess wrap with sharp scissors or utility knife.
3. If your wrap isn’t wide enough add another row, right up against the first and seal the seam with clear packing tape.
Note: Sealing edges with tape may improve results, but is likely to lift paint when removed, so I would avoid this unless you plan to repaint or replace windows in the spring.
Does the Bubble Wrap Really Insulate the Windows?
Yes. It helps. I can feel a noticeable difference in heat loss. There is very little reduction in the amount of light coming through, and with window treatments over it, it is completely unnoticeable. Removal in spring will be as simple as peeling it off. I wish I had done this quick and easy energy saving trick before.
