This part of BS 6262 gives information and recommendations for vertical glazing in the external walls and interiors of buildings, with respect to: structural sealant glazing; bolt fixed structural glazing; frameless doors and entrances; mirrors. Bolt fixed structural glazing with countersunk holes is not specifically covered. NOTE some guidance is also given on non-vertical use of mirrors. These recommendations do not apply to: patent glazing (see BS 5516-1); glass in non-vertical applications (see BS 5516-2); glazing for furniture and fittings (see BS 7376 and BS 7449); glazing for commercial greenhouses (see BS 5502-21); glazing for domestic greenhouses. Requirements for standards of workmanship for the application of sealants have been published separately as BS 8000-16, and therefore this subject is not dealt with in this standard.
