This Technical Circular gives guidance on the use of fire doors (FD20) within dwellings to comply with Building Regulations
Requirement B1.
The guidance applies solely to locations within a dwelling, i.e. either within a single family dwelling house or a within an individual flat where the Approved Document B 2006 guidance refers to the use of a door to provide an FD20 standard of fire protection.
The guidance also only applies to the installation of new fire doors. In instances where it is proposed to upgrade existing doorsets reference should be made to BCA Technical Guidance Note 4 which covers the upgrading of existing door leafs and
framesets.
Boiler flues have been a subject of discussion in the last few years, primarily due to issues raised within CORGI`s technical bulletin 200 which addresses some aspects of the installation of room sealed flue systems within voids. Whilst this provides for the access and inspection of flues inspecting officers form public and private sectors have noted that there appears to be a lack of knowledge by site operatives etc. in the installation of boiler flues and other ducted ventilation perforations within timber frame buildings.
Any perforation within the external walls of a timber frame building need to take into account the relevant requirements of Parts B, C, J & L. It has been discovered that in the majority of cases, appropriate installation instructions are not provided or highlighted within installation or manufacturers manuals/guidance to address timber framed buildings. This has created a “custom and practice” approach by installers which generally does not comply with the goals required in the above mentioned Parts of the Building Regulations and in some cases miss the provisions altogether leaving dangerous conditions, latent defects or both.
This advice note is for single family dwelling houses only— it should be noted that both Approved Document B1and BS9991 take account of both the safety of building occupants and fire fighters,
Reference is also made in this advice note to a recent determination by DCLG that has a direct bearing on this guidance note.
The key requirements of the Approved Document and BS 9991 are very similar but have been presented to enable a direct comparison to be made between the various requirements.
