In internal and external walls in terms of safety (BS 6262 part 4)
Safety glass is required on any panel below 1500mm from the floor on a door or within 300mm of a door. It is also required on any panel within 800mm of the floor.
Laminated glass is also strongly recommended for security. Because it is constructed of two layers of glass with a plastic interlayer it resists casual break-in attempts.
Darker areas show critical locations to which requirement N1 applies (ie. glazing in areas numbered 2, 3, 5, 6, 7, 9, 10, 11, 12).
