Fire Safety & Compliance in Every Detail

How Intumescent Letter Plates Protect Your Building

Intumescent letter plates are an essential upgrade for any FD30 fire door with a mail slot. The built-in heat-activated seal expands in a fire, creating an airtight barrier that stops flames and smoke passing through.

Perfect for apartments, HMOs, schools, healthcare facilities, and offices, they are tested to BS 476 and EN 1634-1 to meet strict UK fire safety standards.

Pair them with intumescent and smoke seals or door closers for complete fire door compliance.
