worked perfectly

Sometimes caulking or spray foam is not appropriate for the job, and is an excellent permanent base fix prior to caulking. Creates no pressure on door and window frames

Made up 20F difference before and after. I inserted this into a narrow gap between baseboard and floor. Wish I could've got 0.5', but a couple of go for this worked perfectly as well.
