Scottish Technical Handbooks - Section 4

Section 4 of the Scottish Technical Handbooks, Approved Document M to the Building Regulations (England and Wales), and Technical Booklet R to the Building Regulations (Northern Ireland) relate to accessibility for all persons entering and using buildings.

Please note, a new version of Section 4 comes into effect from 1 May 2007.

These Documents specify the size and location for glazed panels in doors in various situations, in order to promote safety and accessibility. Visual contrast on the leading edge of doors is also included, as are opening and closing forces for ease of door operation, threshold height and door width requirements.
