For a basement ceiling, fiberglass batt insulation is commonly recommended due to its effectiveness in preventing heat transfer and its ability to absorb sound. This type of insulation is available in pre-cut panels that fit easily between ceiling joists, making it relatively simple to install.
Faced insulation has kraft paper attached to it, which enhances its sturdiness and prevents it from falling. Unfaced insulation lacks this paper but performs similarly.
Spray foam becomes tack-free in 5 to 60 minutes and fully cures in about 8 to 24 hours, depending on the product and conditions.
