A security double-glazed unit is a sealed unit in which one or both panes are laminated glass, usually the inner pane, so the window keeps its insulation but resists being broken through. It fits the same frame as a standard unit and is the simplest way to add security to modern windows and doors.

Fitting in Gloucester and nearby

Surveys in Gloucester (GL1) are booked around installer availability, as they are in nearby Cheltenham (7 miles) and Stroud (8 miles).

Gloucestershire pairs Cheltenham's Regency terraces and shopping promenades with Gloucester's docks and city centre, and Cotswold-stone towns where conservation areas shape window changes.

Typical settings for security double-glazed units:

Ground-floor and basement windows
Glazed back and side doors
Replacing misted or damaged units
Patio doors and bifolds

Getting the right glass for your building

Which pane is laminated

Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.

Internal or external beads

If your beads are on the outside, we add security tape or clips so the unit cannot be lifted out after the beads are removed.

What the rules say in England

England

Listed buildings and conservation areas

In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.

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.
