🔥 Introducing the premium-grade intumescent for flush bolts to suit Radius and Square 609/914mm Flush Bolts — a professional, reliable and fire-safe sealing solution designed specifically for fire-rated doors fitted with flush bolts. Engineered with advanced intumescent technology, this product ensures that your door system remains fire-resistant, smoke-controlled and building-compliant while maintaining a sleek and concealed finish. Ideal for commercial, residential, architectural and industrial fire door applications, this product is formulated to expand aggressively under heat, sealing gaps around flush bolt housings and preventing heat transfer, smoke leakage, and fire penetration in vulnerable locking areas. 🚪🔥🛡️

This intumescent for flush bolts is compatible with both Radius and Square flush bolt cutouts, making it a universal premium-fit solution for modern door systems using 609mm and 914mm flush bolts. The product is designed to fill, protect and fire-seal metal hardware cavities where temperature, metal-contact and internal gaps can compromise fire-door ratings if left unprotected.

🧩 WHY IS THIS INTUMESECENT FOR FLUSH BOLTS REQUIRED?

Flush bolts are installed inside the door core, creating a recess or pocket where heat can travel quickly through metal components. During a fire, metal expands rapidly and becomes a heat-transfer bridge, causing the door leaf to lose insulation performance. Without proper flush bolt intumescent sealing, this vulnerable zone can allow fire, smoke & toxic fumes to pass, reducing door rating and safety duration.

This radius and square compatible intumescent acts as an automatic fire-expanding barrier, offering:

✔ Heat-activated expansion
✔ Smoke-containment sealing
✔ Thermal insulating protection
✔ Hardware cavity closure
✔ Maintained fire-door certification
