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.

Getting the right glass for your building

Units with blinds inside the glass can be made with a laminated pane, but lead times are longer.
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.
What the rules say in England
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.
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 Sutton: questions
Do you cover Carshalton as well as Sutton?
Yes. As well as Sutton, we can arrange surveys in nearby Carshalton, Banstead and Ewell. Dates depend on installer availability.
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.
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.
Do you work on aluminium bifolds?
Yes, on aluminium, uPVC and timber doors, provided the frame can take the new unit thickness.
