Getting the right glass for your building
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.
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.
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 Hitchin: questions
Do you cover Letchworth Garden City as well as Hitchin?
Yes. As well as Hitchin, we can arrange surveys in nearby Letchworth Garden City, Stevenage and Luton. 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.
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.
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.
