Fire Stopping Around Doors in Windsor

From the SL4 district outwards, we cover Windsor and neighbouring towns such as Slough and Egham for fire stopping works.

Fire stopping is the sealing of gaps and openings in fire-resisting walls and floors so fire and smoke cannot pass through. Around a fire door it mainly means the gap between the door frame and the wall, which must be sealed as well as the door itself.

Common questions in Windsor

Is expanding foam acceptable around a fire door frame?

Only a fire-rated foam with evidence for that use and gap size. Ordinary expanding foam is not suitable. BS 8214:2026 lists acceptable approaches such as suitable mastics, foams and stone wool.

Which fire safety law applies in Windsor?

Windsor is in England, so the Regulatory Reform (Fire Safety) Order 2005 applies, together with the Fire Safety (England) Regulations 2022 for multi-occupied residential buildings.

Do you cover the area around Windsor?

Yes. As well as Windsor itself we cover nearby towns including Slough, Egham and Staines.

Can you fire stop a whole building?

This service covers fire stopping around doors and nearby penetrations. Wider compartmentation surveys need a specialist survey, which we can arrange.
