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.

What you can specify

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

Fitting in Chesham and nearby

We arrange surveys and fitting in Chesham and across the HP5 postcode district, as well as in nearby Amersham (2 miles) and Berkhamsted (4 miles). Dates depend on installer availability.

Milton Keynes' glass-fronted shopping centre and business districts contrast with Buckinghamshire's older towns, where Aylesbury, Amersham and Marlow keep many period shopfronts.

Typical settings for security double-glazed units:

Replacing misted or damaged units
Ground-floor and basement windows
Windows in flats on walkways and balconies
Glazed back and side doors

Getting the right glass for your building

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.

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.

What the rules say in England

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.

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.

Security double-glazed units in Chesham: questions

Do you cover Amersham as well as Chesham?

Yes. As well as Chesham, we can arrange surveys in nearby Amersham, Berkhamsted and Chalfont St Peter. Dates depend on installer availability.

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.

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.

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.
