The Carlisle Brass 1.05m Fire & Smoke Door Seal (5 Pack) is designed to enhance fire‑door performance by sealing the gap between the door and frame in the event of a fire. These intumescent seals remain inactive for years, only activating when exposed to high temperatures. The intercalated graphite core expands multi‑directionally up to 10–15 times its original size, forming a protective barrier that helps contain flames, smoke, and hot gases. The integrated smoke seal also provides continuous cold‑smoke protection, reducing smoke spread even before the intumescent material is activated.

Key features:

• Intumescent fire and smoke seals for enhanced door protection
• Designed to seal the gap between door and frame during fire conditions
• Dormant until exposed to rising heat and pressure
• High‑performance graphite core expands up to 10–15× its size
