Horizontal Foam Joint Seal with UV Stability and Waterproofing
Willseal® Color Coreseal H is a flexible closed-cell foam joint seal engineered for horizontal applications that require durability, moisture protection, and thermal stability. Built from ethylene vinyl acetate (EVA) copolymer foam and coated with a traffic-rated silicone sealant, this solution ensures watertight, dustproof, and airtight performance. Its monolithic design resists delamination, chemical damage, and puncture while supporting rapid joint movement in dynamic environments.
Key Benefits
- Watertight Seal: Closed-cell EVA foam blocks water intrusion in dynamic horizontal joints.
- UV and Chemical Resistance: Durable silicone skin offers puncture and chemical protection.
- Custom Color Options: Available in standard or custom-colored silicone sealant finishes.
- Flexible and Easy to Install: Supports ±25% movement and requires non-invasive anchoring.
- Long-Lasting Performance: Will not delaminate under environmental stress.
