Security glass for doors replaces the glazed panel in a front, back or side door with laminated safety glass, usually in a sealed unit with a toughened outer pane. It stops the common trick of breaking the glass to reach in and turn a key or thumb-turn left in the lock.
What goes into security glass for doors
- Laminated inner pane with toughened outer pane
- Glass for side panels and fanlights beside the door
- Laminated backing for leaded and bevelled panels
- Safety glass suitable for critical locations
- Composite door cassettes where available
- Internal beads or security tape so glass is much harder to remove from outside

What to think about first
Thumb-turns and keys
Laminated glass makes reaching a thumb-turn far harder. Keeping keys away from the door helps too.
Composite door glass
Some composite doors use a cassette made by the door's maker. We check whether a laminated version is available before quoting.
Consents and safety: 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.

Security glass for doors in Welwyn Garden City: questions
Can you survey in Welwyn Garden City and nearby towns?
Yes. Surveys in Welwyn Garden City, Hatfield and Hertford are booked around installer availability.
Does door glass have to be safety glass?
Yes. Glass in doors up to 1,500 mm from the floor, and in side panels within 300 mm of the door edge, counts as a critical location and needs safety glass or protection.
Can you replace glass in a composite door?
Often. Some composite doors take a standard unit; others use the maker's own cassette, which we source where possible.
Can you keep my stained or leaded glass design?
Usually. We add a laminated pane behind the decorative glass inside the sealed unit, or have a matching unit made.
