DIY Spray Insulation to Seal Gaps
LESLIE: Mike in Michigan needs some help with an insulation project. What can we do for you?
MIKE: Well, I’d like to know if there’s a do-it-yourself spray-in insulation, to do in my rim joists?
TOM: So to do the entire rim joist, it’s probably too big for a product like GREAT STUFF but that’s pretty much the only do-it-yourself spray-foam insulation. If you’re talking about a product like Icynene, that’s put on with very specialized equipment and it’s definitely not do-it-yourself.
But if you’re just trying to seal gaps around the rim joists, why not invest in a few cans of GREAT STUFF? It’s very effective and it expands to fill all those cracks and crevices. You could do the rim joists and then you could put some fiberglass insulation batts on top of that after it dries and it should be quite warm.
MIKE: Well, thanks a lot.
TOM: You’re very welcome. Thanks so much for calling us at 888-MONEY-PIT.
