Getting the right glass for your building
Laminated inner or both panes
A laminated inner pane is the usual security upgrade. On very exposed doors both panes can be laminated.
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.
What the rules say in England
Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Patio and bifold door security glass in Greater London: questions
Which towns in Greater London do you cover?
We can arrange work anywhere in Greater London, including Central London, Islington, Bexley, Barking and Archway, and in other towns across the area.
Can you replace just one pane of a bifold?
Yes. Each leaf takes its own unit, so we can upgrade one leaf or all of them.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
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.
