Why do I need glass manifestation?
The manifestation of glass is a legal requirement in areas where there is a risk of human impact (Workplace Health & Safety Welfare Approved code of practice L24 Regulation 14). The requirements are also incorporated in Building Regulations BS 6262 Part 4 Safety.
The regulations relate to the glazing of internal and external walls, in public or non-domestic buildings known as critical locations.
On May 1st 2004 a new regulation Document M – Access to and Use of Buildings (2004 edition) was issued. This refers to critical locations in new buildings and refurbishments of existing buildings. From this date it is a duty of care that states the following:
Glass entrance doors and glazed screens will satisfy Requirement M if:
A) They are clearly defined with manifestation on the glass at two levels, 850 to 1000mm and 1400 and 1600mm above the floor, contrasting visually with the background seen through the glass (both sides from inside and outside) in all lighting conditions.
B) Manifestation takes the form of a logo or sign at least 150mm high (repeated on glazed screens) or a decorative feature such as broken lines or continuous bands, at least 50mm high.
