Security glazing in Pontypool

Security rules for new homes

Wales introduced its own Approved Document Q for new homes, in force from 1 November 2018, and it applies to newly erected dwellings only. It follows a similar approach to England's, with PAS 24 referenced for easily accessible doors and windows and laminated glass to BS EN 356 P1A in doors and nearby windows. It does not apply to changing the glass in an existing home.

Replacing glass in an existing frame

Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.

Safety glass in critical locations

In Wales, safety glazing is covered by Approved Document N (glazing) under the Welsh Building Regulations rather than Approved Document K. Glass in doors up to 1,500 mm above the floor, in panes within 300 mm of a door up to 1,500 mm, and in other glazing below 800 mm should be safety glass or protected. Laminated and toughened glass are the usual choices.
