Contractors and safety-conscious homeowners, this fire barrier sealant is serious protection for your building!

The 20-ounce tube is perfect for caulking gun application, making it easy to seal gaps and penetrations that could allow fire to spread.
The intumescent material is what makes this stuff special - when exposed to heat, it expands to create a solid char that seals off openings.

This gives you up to a 4-hour fire rating, which is crucial for meeting building codes and keeping people safe.
Application is straightforward - just load it into a standard caulk gun and apply it to clean, dry surfaces around pipes, electrical conduits, ductwork, or any other penetrations through fire-rated walls and floors.

The red color makes it easy to see where you've applied it during inspections.
Made right here in the United States, so you know the quality standards are high.
