USG ME sealants are acrylic-based for use as sealants in fire-rated partitions, smoke barriers and sound-rated assemblies as acoustical barrier. The sealant exhibits exceptional structural integrity, forms a continuous flexible bead that resists collapse and flows into all but the most intricate joints, resists water penetration and offers excellent resistance to thermal shock.
These sealants are low-flowing, forming a dense and continuous barrier against air and other gases. It provides excellent resistance to vibration and movement, making it ideal for joints in fire-rated assemblies that have little or no movement, they're produced with high fire rating and acoustical performances.
Where the acoustical sealant which is a type of sealant that is specifically designed to reduce the transmission of sound through gaps or cracks in walls, ceilings, and floors. It is often used in construction and renovation projects to improve the acoustics of a space and reduce noise pollution. While the fire rated sealant is a type of sealant that is specifically designed to prevent the spread of fire. It is often used in buildings to seal gaps and joints in walls, floors, and ceilings in order to create a fire-resistant barrier. Fire rated sealants are typically made from intumescent materials, which expand when exposed to heat in order to block the passage of flames and smoke. They are tested and rated by independent organizations to ensure that they meet certain fire resistance standards.
