Glazing (Wales only)
Approved Document N (Glazing — safety in relation to impact, opening and cleaning) was withdrawn in England in April 2013 when its requirements were absorbed into Approved Document K. Wales has not adopted this change: Part N remains a standalone Approved Document in Wales, governing safety glazing in critical locations (below 800mm in walls, in doors, in side panels), the safe opening and cleaning of windows, and impact protection. Homeowners and builders in Wales must refer to AD N rather than AD K for glazing safety requirements.

The buildwiz build guides walk through a UK extension in sequence and link to Part N (and every other Approved Document) at the exact stage it bites. That is usually a more productive way to use this material than reading the document cover to cover.
