Timber frame walls and floors: Fire resistance of service penetrations

TRADA image

Although extensive testing of the fire resistance of all forms of timber loadbearing elements has been performed over many years, in almost all cases, the tests have been undertaken on notionally “perfect” elements. For example, service penetrations into, or through, an element have not been included in test panels. In actual buildings, however, there are few loadbearing construction elements which do not have some form of service penetration, eg water pipes, electric cables and ventilation ducts.
