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.

- Integral blind units replaced like for like where possible
- Security tape on externally beaded frames
- Laminated inner pane with toughened outer pane
- Anti-lift and lock checks on sliding doors

Things to decide before you order
Integral blinds
Units with blinds inside the glass can be made with a laminated pane, but lead times are longer.
Laminated inner or both panes
A laminated inner pane is the usual security upgrade. On very exposed doors both panes can be laminated.
Rules that apply 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.
Planning permission
Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.

Patio and bifold door security glass in Caterham: questions
Can you survey in Caterham and nearby towns?
Yes. Surveys in Caterham, Coulsdon and Purley 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.
Will laminated glass make my bifolds harder to open?
Units are slightly heavier. We adjust hinges, rollers and carriages after fitting so the doors run smoothly.
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.
