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.
This Wood Information Sheet gives guidance on assessing the suitability of existing doors for upgrading to give a 20 or 30 minutes' fire resistance comparable with that of purpose-made fire doors. Upgrading to 60 minutes' performance will rarely be possible.
Upgrading the fire resistance of existing doors is a...
No one who follows the news can fail to have noticed the headlines in both construction press and indeed national media on the subject of timber frame design and fire safety. In this first of a series of articles, Rupert Scott MIFireE, Membership Manager for TRADA, reviews the statistics and...
Timber frame construction of some description is a method which has been around for millennia; however over time it has become a tremendously refined practice to the point that – as buildings of up to six storeys become widely used in England and Wales – timber frame constructions of today...
