Hey guys before I start any of this insulation work do you think I should have a sump pump installed to deal with the moisture? Right now I have no moisture controls in the basement other than a dehumidifier.Yes. This is a great start and you can just use a dab of adhesive from a caulk gun to attach the foam. Just use one meant for foam as some of the construction adhesives will melt the foam.1). Insulating Rim Joists. I found R10 2" thick rigid insulation, that seems to be the correct one for this job. along with spray foam to insulating around the grooves of the insulation. Do I install the insulation with adhesive or screws?
This will make a huge difference in stopping the cold air coming in. It's also a real security upgrade.2). Install insulated exterior door (with pressure treated wood frame) in entry way to prevent heat escape from bilco doors.
This one is a little more debatable if you consider the cost vs return. You can get a similar effect by just sealing a little better around the window or adding another layer to act similarly to a storm window. I've seen those hair dryer shrink plastics used or plexi if you don't have any need for egress. They also make snap in storms that go on the inside. That could work well here if you can get a good seal around the edges.3). Replace old single pane windows with new double pane. Any specific windows? or just any double pane that will fit in the space?
