How the Intumescent Works

The 1mm Universal Bathroom and Sashlock Intumescent is made of heat-reactive material that remains inert under normal conditions but rapidly expands when exposed to temperatures typical of a fire. This expansion fills cavities around the lockcase and door recess, preventing the passage of heat, smoke, and toxic gases. The pad acts as a critical component of passive fire protection, ensuring that the door retains its fire rating for the duration specified by its certification.

By combining the 1mm Universal Bathroom and Sashlock Intumescent with other fire-rated hardware such as hinges, flush bolts, and door seals, installers can create a comprehensive fire-protection system that significantly improves occupant safety and property protection.

H3: Installation Guide

Measure and Trim: Cut the pad to the required size if necessary, ensuring a snug fit within the lock cavity or hinge recess.
Position the Intumescent: Place the pad behind the lockcase or along the sashlock cavity.
Secure the Pad: Use adhesive backing, screws, or other mechanical fixing methods as per door manufacturer instructions.
Check Operation: Ensure the lock or bathroom hardware moves freely without obstruction.
Final Inspection: Verify that the intumescent pad covers all gaps and maintains flush alignment for optimal performance.
