What is the price of security double-glazed units in Hertford?

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.

Laminated inner pane, outer pane or both
Warm-edge spacer bars in black, grey or white

Questions we will ask at the survey

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.

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.

Building regulations and safety 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.

Security double-glazed units in Hertford: questions

Which areas near Hertford do you cover?

We can arrange work in Hertford and in nearby Hoddesdon (4 miles), Welwyn Garden City (6 miles) and Hatfield (7 miles). 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.

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.

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.
