Firestop ES-105 Elastomeric Sealant is a non-halogenated latex-based, highly elastomeric caulk designed to provide passive smoke and fire protection in construction joints. This material is also designed to restore sound attenuation properties to sound-rated ceilings and partitions. Firestop ES-105 Elastomeric Sealant is engineered to adhere to virtually all construction surfaces and may be applied using standard caulking equipment or by troweling. SpecSeal ES Elastomeric Sealant dries to form a flexible shield against the propagation of fire. Its premium latex binder
system is totally resistant to water and will not re-emulsify after drying. SpecSeal® ES Elastomeric Sealant contains no inorganic fibers, asbestos, or solvents.Contact Us.
