What is used to prevent adhesion to specific areas in joints?

The use of a bond breaker is essential in firestop applications and other construction scenarios where adhesion needs to be controlled. A bond breaker is a material or component placed in joints to prevent adhesive from bonding to specific areas. This allows for controlled movement and flexibility within the assembly, which is especially important in fire-resistant systems where gaps may develop over time due to thermal expansion or contraction.

Bond breakers facilitate the free movement of construction elements without transferring stresses where they should not be, thereby maintaining the integrity of firestop systems. They are commonly used in horizontal and vertical joints to ensure that the sealant or firestop system can function as intended, sealing off penetrations and maintaining fire resistance without becoming rigid or cracked.

Understanding the role of a bond breaker helps in recognizing its importance in maintaining the performance of firestop systems and ensuring compliance with fire safety codes and regulations.
