My house inspection noted that the exposed blue foam insulation in my basement is not to code and (if there’s a fire) could be dangerous due to noxious fumes. The insurance provider has told me to remove it, or cover it with drywall to ensure ongoing coverage. I am trying to decide which path to take, without spending a large amount of money.
Options (as I see them):
- Remove it
- Cover with drywall (without framing) and using concrete news/screws
- Vapor barrier, frame it, cover it with drywall (probably not actually an option because I can’t afford it with current lumber prices)
- Something else?
More Context: I’m in Atlantic Canada (winters are long and cold). The house is old (1928), and already not very efficient. The basement is not usually wet, but there can be some pooling/dampness when the snow thaws in spring. With this in mind, I’m worried that covering the blue foam with drywall might present a mold issue unless I invest much more money in the solution.
Question: Am I crazy to remove the foam entirely? Will I be affecting efficiency a ton by doing this? (this is my favorite option)
- The foam does not cover all walls. Probably about 2/3 of the basement wall surface is covered.
- I have no plans to ever finish the basement
- I can’t afford to fully waterproof my foundation at this time (we have a sump pump, and that will have to do for now)
