Farnham Castle steel framework


12th century Farnham Castle protected with intumescent steel paint to meet building regulations.

The 12th century Farnham Castle was formerly the Palace of the Bishops of Winchester. Now it houses the International Briefing and Conference Centre, which welcomes many overseas visitors each year for residential conferences and courses. Rapid expansion of their services has necessitated the creation of new offices in the area underneath the ancient chapel.

The chapel itself is supported on a steel framework installed in the 1930s, which replaced the original timber structure. The massive steel girders have never before been protected against the effects of fire. In order to comply with the UK building regulations and current fire regulations, the steel structure had to be upgraded to modern standards.

Ted Milam, Head of Maintenance at Farnham Castle, contacted John Wallis of County Passive Fireseals in East Sussex, previous supplier of upgrading systems for wooden doors, to provide a solution. In view of the restricted access and lack of ventilation, the Envirograf® Product 83 intumescent coating system for steel was specified. This product has a low-odour formulation which can be applied by brush in confined spaces, whilst maintaining correct product film thickness for one-hour fire protection.
