The foam sealant acts fast and efficiently by chemical curing action. When I tried it on the ceiling rafters in my basement, it skinned over in just 30 seconds. And curing was done in under a minute. The package can give foam cover for about 620 board feet.

The closed cover sealant is ideal for use in ceilings besides band or rim joists, cavities in walls, crawl spaces and ductwork in attic and insulation, and support for plumbing wall pipe.

Budget Benefits

So, considering the long-term benefits spending on the foam sealant may be worth it.
