Sealing has been defined as "the art and science of preventing leaks". Sealants are use to seal joints and openings ( gaps ) between two or more substrates. The main purpose of a sealant is to prevent air, water and other substances from entering or exiting a structure while permitting a certain amount of movement of the substrates. An air barrier is a type of sealant, but it performs a specific objective in that it forms an monolithic air seal across the entire wall.
