Fire Board Encasements in Hampshire, West Sussex and the South Coast
Structural steel loses its load-bearing capacity rapidly when exposed to fire. Without protection, a steel frame can fail within 15-20 minutes of fire exposure. Fire board encasements - columns, beams and other structural steel elements enclosed in fire-rated boards - protect the structural integrity of the building during a fire, providing the time needed for safe evacuation and firefighting operations.
This service is delivered through our specialist sister company, Aran Fire Protection - FIRAS-certified passive fire protection specialists with over 25 years of experience. Arundel Firecare, Security & Electrical remains your single point of contact throughout.

Fire Board Encasement Services - Hampshire and West Sussex
Fire board encasements protect structural and service elements by enclosing them in a system of fire-rated boards that insulate the element from heat for a specified period. The period of protection (30, 60, 90 or 120 minutes) is determined by the building's fire strategy and structural engineer's specification. Board systems are typically used as an alternative to intumescent coatings where a clean, paintable surface finish is required or where the structural element is in a location that makes spray application impractical.
Steel columns, beams and structural frames in commercial buildings require fire protection under Building Regulations. Fire board encasements for structural steel achieve their required fire resistance through a calculated thickness of board, determined by the section factor of the steel member and the required fire resistance period. All installations are carried out to the board manufacturer's system specification and FIRAS certification provides documented evidence of compliant installation.
Service risers - vertical shafts carrying pipes, cables and ducts between floors - represent a significant fire spread pathway if not correctly protected. Fire board encasements around service risers maintain the fire resistance of the floor at the riser location and prevent fire spreading vertically through the building via the riser shaft. Similarly, horizontal ductwork that passes through fire compartment walls must be protected either by fire-rated dampers or by encasement in fire-rated board.

Frequently Asked Questions
A fire board encasement is a passive fire protection system in which structural steel, service risers, ductwork or other elements are enclosed in a system of fire-rated boards. The boards insulate the enclosed element from heat during a fire, maintaining structural integrity or service continuity for the specified fire resistance period (typically 30, 60, 90 or 120 minutes).
