Security double-glazed units in Letchworth Garden City (SG6)

What is the price of security double-glazed units in Letchworth Garden City?

As a guide, allow £174 to £594 including VAT (£145 to £495 plus VAT) per unit for security double-glazed units in Letchworth Garden City, 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.

Questions we will ask at the survey

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.

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.

Building regulations and safety in England

England

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 Letchworth Garden City: questions

Do you cover Hitchin as well as Letchworth Garden City?

Yes. As well as Letchworth Garden City, we can arrange surveys in nearby Hitchin, Stevenage and Luton. Dates depend on installer availability.

How long do new units take?

Units are made to order after the survey. Lead times vary with glass type and size, and we confirm them when we quote.

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.

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.
