**⭐ 1mm Flush Bolt Intumescent to suit VS21 – Professional Fire Door Safety Enhancement ✨**

The 1mm Flush Bolt Intumescent to suit VS21 is a specialist fire protection pad engineered for VS21 flush bolt installations on certified fire doors where compliance, safety performance, easy installation, and hardware compatibility are essential. This fire rated flush bolt intumescent pad has been designed to expand under intense heat, sealing hardware cavities and minimising smoke, fire, and hot gas transfer, ensuring the structural and safety integrity of the door remains protected during a fire emergency.

Ideal for new construction projects, refurbishment, commercial safety upgrades, and property compliance, this VS21 bolt pad ensures that no unprotected gaps remain behind flush bolt hardware — a common and often overlooked failure point in fire door installations.

🔶 Why This Product Matters

🔶 FAQs

Q1: Is this only for VS21 flush bolt systems?
Primarily yes, but suitable for similar sized systems only if project guidance allows.

Q2: Does it affect bolt operation?
No. The 1mm thickness is chosen for precision, allowing smooth performance.

Q3: How long does it last?
It is a passive, long-life fire safety solution — no expiry under normal building conditions.

Q4: Can I use thicker pads for added safety?
Not recommended — incorrect thickness may cause bolt malfunction, reducing compliance.

Q5: Does this help with smoke and gas sealing?
Yes — it expands under heat to form a sealing barrier, reducing transfer risk.
