Doors and windows
Since 1 April 2002 building regulations have applied to all replacement glazing. The regulations apply to thermal performance and other areas such as safety, air supply, means of escape and ventilation.
An external window or door is a controlled fitting under the Building Regulations and as a result of this classification these regulations set out certain standards to be met when such a window or door is replaced.
