Ensuring all the components of a doorset combine to give the required performance on site is a major challenge for any specifier. Here we outline how current Building Regulations apply to an internal door
1 Part E sound reduction Doors may need to be specified with a minimum door leaf weight (kg/m2) or sound reduction value (Rw dB) to ensure sound transmission is kept within acceptable levels. This is particularly important for music rooms in schools or hotels.
2 Part B fire resistance and smoke control It needs a label demonstrating third party accreditation for fire (such as BWF-CERTIFIRE) to demonstrate the doorset’s ability to meet a specified fire performance.
3 Part M accessibility A minimum clear opening of 800 mm is needed for accessibility
4 Part N glazing safety This defines the type of glazing that must be used for vision panels
5 BS 8300 Sets the handle position, its shape and colour contrast with door face for to meet accessibility requirements
6 BS 7532 Selection of the correct hinges for usage, door weight, width and door-closer requirements
7 Part E accoustics Design of the thresholds is essential for meeting sound reduction requirements
8 Parts B and E Selection of intumescents seals and smoke seals for fire protection or acoustic seals for sound protection
9 Part M Vision panel design to aid visibility
10 Parts B and E Packing and sealing of frame/wall junctions to limit spread of fire and noise.
