Description

This Universal Intumescent Deadlock Kit is an essential passive fire protection product designed specifically for use around deadlocks installed in timber fire door assemblies. Made from a flexible graphite material, this kit has been extensively tested to meet fire standards including BS 476 Part 22 and BS EN 1634-1, making it suitable for both 30-minute and 60-minute timber applications. The core mechanism is activated by heat, where the graphite begins to expand when heated to approximately $180^\circ\text{C}$, achieving up to 30 times its original volume. This rapid expansion effectively seals the gaps around the deadlock, preventing the passage of fire and smoke. The material is completely non-toxic, non-fibrous, safe to handle, and remains unaffected by moisture, humidity, or atmospheric pollution, ensuring long-term reliability.
