So I know some of us here, have home projects and have some experience in handling these types of things. Thought I'd make this kinda thread to assist not only myself, but other members if theyre as clueless as me when it comes to home improvement. So my question, my house is an older home (1927) and it tends to get pretty cold and I have a hard time getting it to stay at around 69-71 degrees. I put in new windows, hardwood floors amongst other upgrades. Thing is, its getting way too pricey, and I feel I can save lots of money by trying to tackle it on my own. So, I wanna use the spray foam insulation, has anyone had any problems, good outcomes with the thing? Besides the obvious health hazards, is there anything else I should educate myself before deciding to insulate my crawlspace with this stuff? And also, does weather stripping for doors help alot?
