Patio and bifold door security glass means fitting large sealed units with a laminated pane into sliding, French or bifolding doors. These doors are usually the biggest glass at the back of the house and out of view, so making the glass hold when it is struck closes one of the easiest routes in.

What to think about first
Door hardware
Glass is only part of the picture. Worn rollers, missing anti-lift blocks or old locks are often worth fixing at the same visit.
Solar control
South-facing doors can overheat. Adding solar control glass at the same time keeps rooms cooler.

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.
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.

Patio and bifold door security glass in March: questions
Can you survey in March and nearby towns?
Yes. Surveys in March, Wisbech and Peterborough are booked around installer availability.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
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.
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.
