Sashco Log Jam Chinking sets the standard for high-performance log home sealants. Known for its exceptional durability and elasticity, this synthetic chinking material is the only one on the market with a UL fire rating, ensuring superior protection for your log home.

Key Features:

• UL Fire Rated: Log Jam is the only synthetic chinking to hold a UL fire rating, providing an added layer of safety for your home.
• Elastic and Durable: Designed to stretch and compress with the natural movement of your logs, Log Jam maintains a tight seal even as logs swell and shrink, protecting your home from wind, weather, and insects.
• Long-Lasting Performance: With its remarkable elasticity, Log Jam can stretch and compress up to twice the original joint size without losing its integrity, ensuring long-term protection.
• Authentic Look: While it behaves like high-performance synthetic chinking, Log Jam retains the classic appearance of traditional log cabin mortar, blending seamlessly with your home’s rustic style.
