Adhesives and Sealants are used in construction to prevent fluids and other substances from passing through material surfaces, joints, or openings. They can also prevent the passage of air, sound, dust, insects, and so on, as well as acting as a firestopping component. A gasket can be used for many different purposes, but generally, it serves as a flexible seal that fills the space between two components joined under compression, preventing leakage through the gap between it.
