Construction sealant is a type of sealant that is used in construction and building to seal gaps, joints, and cracks between different building materials. It is used to prevent air, water, dust, and other contaminants from penetrating the building envelope. Construction sealants are typically made of rubber, silicone, or polyurethane, and are available in different formulations for specific applications. They can be used to seal gaps between walls, floors, and ceilings, as well as around windows, doors, and other openings. Construction sealants can be applied in different ways, depending on the type of sealant and the specific application. They can be applied by hand, using a caulking gun, or by machine. They can also be applied as a spray, a foam, or a paste. Construction sealants have to meet strict standards and regulations, and they are often tested for their adhesion, flexibility, durability, and resistance to weathering, UV radiation, and temperature changes. Construction sealants play a crucial role in ensuring the energy efficiency, weather-tightness, and durability of buildings. They also help to prevent drafts, reduce noise, and improve the overall comfort of a building.
