Re: Thermal curtains? Cheap solutions to seeping cold around delicate old windows?
I wouldn't recommend what you propose, as it will surely result in mold and mildew. Proper repairs are the ONLY way to deal with issues, bandaids only add to the expense of the project when you have to tear it all out and replace it again due to failure and increased damage.
The only temporary thing I can suggest is the shrinkwrap plastic sheathing for windows. You tape the plastic around the window, then hit it with a hair dryer to shrink the wrinkles out. This acts as a storm window of sorts, kits should be readily available at your local hardware store or big box.
As for the walls, I would suggest looking into blown insulation. Typically, holes are drilled at the top and bottom of each wall cavity, then cellulose insulation is drawn into the cavity. The holes are then sealed. This will be the least intrusive to your home, but there are other insulation options as well. I would suggest consulting with local insulation contractors familiar with old homes and maintaining the integrity of the structure.
