Tunnel Fire Protection
Fire encasement of smoke-exhaust ducts for road/rail tunnels, utility corridors and underground spaces.
Pain Points
- Tunnel fires are intense and fast — extreme fire-resistance demands
- Humid underground environments need moisture durability
- Hard-to-access sites require long-life, low-maintenance materials
Recommended Product Combo
Fire-rated duct boards (smoke-control systems) + fireproof base boards (equipment rooms/escape routes), with flanges, studs and details.

FAQ
Why do tunnels require Class A1 non-combustible materials?+
Tunnels are enclosed with rapid fire growth and poor smoke/escape conditions; smoke-control systems must stay intact. Class A1 materials add no fuel and spread no flame — a baseline requirement for tunnel fire protection.
