?What are sealants and why are they important in cladding systems?
What will be an ideal response?
?Most cladding systems rely on sealants to maintain weather tightness between components and panels. A sealant is a material used to seal joints between construction members and protect materials against the penetration of moisture, air, corrosive substances, and foreign objects. The sealing of joints between these and other parts of a building is essential to ensure the integrity of the entire structure. If sealants are not properly specified or poorly installed, a leaky building is unavoidable.
