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.

Choices you can make

Security glazing tape or clips where beads are external
Laminated inner pane, outer pane or both
24 mm, 28 mm and other overall thicknesses to suit frames
Toughened outer pane where safety glass is required
Warm-edge spacer bars in black, grey or white
Obscure and decorative glass for bathrooms and doors

Energy performance

Choosing low-E glass, argon and warm-edge spacers keeps the window as efficient as possible, often better than the unit being replaced.

Which pane is laminated

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

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.

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.

Security double-glazed units in Peterlee: questions

Which areas near Peterlee do you cover?

We can arrange work in Peterlee and in nearby Seaham (5 miles), Hartlepool (7 miles) and Houghton-le-Spring (8 miles). Dates depend on installer availability.

Do security units reduce noise?

Laminated glass already damps sound better than plain glass, and acoustic interlayers improve it further, which helps on busy roads.

Will a laminated unit be heavier?

A little. A laminated pane weighs about the same as a solid sheet of the same thickness. On large opening sashes we check hinges and friction stays.

Which pane should be laminated?

Usually the inner pane, so smashing the outer pane does not create an opening. On doors and low panes the outer pane is normally toughened to meet safety rules.
