Security double-glazed units in Kent

How much should I budget for security double-glazed units in Kent?

As a guide, allow £174 to £594 including VAT (£145 to £495 plus VAT) per unit for security double-glazed units in Kent, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free survey.

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

Low-E coating and argon fill for insulation
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
Made to measure for each sash, light and door panel
Security glazing tape or clips where beads are external

What to think about first

Overall thickness

The new unit must suit the frame's glazing rebate. If your frames only take thin units, we use thinner laminates or adjust the beads.

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.

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 double-glazed units in Kent: questions

Which towns in Kent do you cover?

We can arrange work anywhere in Kent, including Maidstone, Gillingham, Chatham, Tunbridge Wells and Folkestone, and in other towns across the area.

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.

Can I just replace the glass and keep my frames?

Yes, if the frames are sound. We measure each unit, make security units to the same size and fit them into your existing frames.
