Arundel Cathedral Fire Door Upgrade

FD30/S Fire Protection & Compartmentation

Heritage Building • West Sussex

Project Overview

Upgrade of 19 existing timber doors at Arundel Cathedral to achieve FD30/S fire performance, alongside improvements to fire compartmentation throughout the building.

Works were carried out within a live heritage environment, requiring a sensitive and compliant approach.

Scope of Works

A total of 19 existing timber doors were upgraded as part of the project.

Intumescent fire & smoke seals installed
Hardwood lipping added
Fire-rated hinges and closers fitted
Intumescent coating systems applied
Fanlight openings sealed
Glazing film installed
Thresholds adjusted

Technical Solution

A specialist intumescent coating system was applied to the existing timber doors, allowing them to achieve 30-minute fire resistance while maintaining their original appearance.

The system expands when exposed to heat, forming an insulating char layer that slows fire spread and protects the underlying material.
