Sizes given are maximum practicable manufacturing limits using normal construction. Safety, security, thermal and weather performance criteria may impose tighter restrictions.
Minimum sizes also apply, dictated by tooling and hardware. Consult Anglia Fixing for guidance on this if a need arises for very small units.
Multipoint fasteners are recommended on all widths over 1200mm and all heights over 1500mm.
Concealed variable geometry friction hinges may not be suitable for the largest hinged casements, which will need to have face mounted butt hinges applied.
Vertically pivoted casements mounted off centre are limited to a maximum length from pivot to jamb of 800mm
Doors framed in hot rolled steel – SMW or W20, - Need stiffening with lock rails and kicking panels
