Glazing rules in Northern Ireland
Replacing glass in an existing frame
Building regulations in Northern Ireland are administered by the eleven councils' building control services. Replacing only the glass in an existing frame is generally treated as a repair, while replacing whole windows or doors can be controlled work, so check with building control first. New glass in a critical location should be safety glass under Part V.
Security rules for new homes
If you are building a new home in Northern Ireland, ask the council's building control service which security requirements apply. In existing homes nothing obliges you to upgrade glass, but laminated glass to BS EN 356 P1A in doors and in windows beside them is a common benchmark taken from guidance in Great Britain.

Patio and bifold door security glass in Lisburn: questions
Can you survey in Lisburn and nearby towns?
Yes. Surveys in Lisburn, Belfast and Newtownabbey are booked around installer availability.
Is patio door glass already safety glass?
It should be, because doors are critical locations. Most is toughened, which is safe but not secure. Adding a laminated pane makes it both.
Can sliding doors be lifted out?
Older sliding doors without anti-lift blocks can be. We check for this at the survey and can fit blocks at the same visit.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
