Building Regulations

There is a requirement to comply with current building regulation requirements. The following is a synopsis of current requirements relating to the installation of windows and doors. We recommend that, in addition to reading these, you consult with your own local authority regarding the use of our windows, doors, screens and other products in your own project.

Historic Buildings

There are some classes of buildings where special considerations may apply in deciding adequate provision for Building Regulations. These specifically relate to the following;

When undertaking work on or in connection with a building that falls within one of the classes listed above, the aim should be to provide improved thermal performance and adequate ventilation as far as is reasonable and practically possible. The work should not prejudice the character of the host building or increase the risk of long-term deterioration of the building fabric or fittings.

Part L - Thermal Performance

In all cases where it is proposed to erect a new dwelling, building regulations require the person proposing to carry out the work to notify a Building Control Body in advance of any work starting. This notification would usually be by way of full plans (or possibly a building notice) given to a local authority, or an initial notice given jointly with the approved inspector. This remains our clients’ responsibility as Architectural Bronze Casements Ltd is not currently registered with a competent persons self-certification scheme such as FENSA. Dependent upon the type of property and nature of the work proposed, planning consent may also be required for works including the replacement of windows and doors.

This applies to new buildings which can be ventilated by either manually controlled trickle ventilation within the window frames, directly through the fabric of the building or through an air management system.

Where replacement windows are provided to existing dwellings provisions should also be made to ensure appropriate ventilation is maintained and is made no worse as a result of a replacement glazing installation.

Part K - Prevention of Falling

In a building that may be used by children under five years of age during normal use, guarding is a mandatory consideration for new buildings and for replacement windows.

Further guidance can be found at:

Part B - Means of escape

In the event of fire or a need to vacate a building as an emergency, adequate means of escape should be provided throughout the entire building - including the ground floor. Windows or doors should enable the person escaping to reach a place free from danger and should be designed such that they will remain in the open position without needing to be held by a person making their escape.
