Highly Intumescent! LCI won't compromise your efforts! Combustible penetrants, insulation, and combustible wall or floor framing demand the performance that only a quality Intumescent caulk can deliver.

A Broad Range of Powerful Systems: LCI has been tested and approved for a wide variety of common applications including metallic, nonmetallic, and insulated pipes as well as all common data, communication, and television cabling. Add ductwork and joint applications and you have everything needed to firestop your next project in a safe yet cost effective manner.

High Quality... Not High Cost! LCI is a premium latex based firestop sealant. Its binder system is totally resistant to water and will not re-emulsify after drying. Cleanup is simple using soap and water. Colored pale red, for easy identification, LCI remains flexible when fully cured allowing for normal pipe movement.

Fully Tested: LCI is the basis for systems that meet the exacting criteria of ASTM E814 (UL1479). Tested systems provide up to a 2 hour fire rating using as little as 1/4" of sealant depth.
