SpecSeal® ES Elastomeric Sealant – High-Performance Fire & Smoke Protection
SpecSeal® ES Elastomeric Sealant – High-Performance Fire & Smoke Protection
The SpecSeal® ES Elastomeric Sealant is a non-halogenated, latex-based, highly elastomeric caulk engineered for passive smoke and fire protection in construction joints. It restores sound attenuation in rated ceilings and partitions, adheres to virtually all construction surfaces, and forms a flexible, moisture-resistant seal that won’t re-emulsify after drying. Free of solvents, asbestos, and inorganic fibers, it is safe, easy to install, and paintable once cured.
Key Features & Benefits
- Water-based for easy application and cleanup
- Non-halogenated and solvent-free for safer use
- Highly elastomeric for joint movement up to ±25%
- Resistant to water and will not re-emulsify after curing
- Adheres to most common construction materials without primer
- Acoustical sealant – helps maintain sound ratings
- Thixotropic for high-build applications
- Paintable when dry for seamless finishing
- Meets LEED v3, v4, and v4.1 low-emitting materials credit requirements
- UL certified and tested to UL2079, ASTM E1966, and CAN/ULC-S115
Applications
- Fire and smoke sealing of construction joints
