What should security double-glazed units cost in Caerphilly?

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
- Warm-edge spacer bars in black, grey or white
- Made to measure for each sash, light and door panel
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Obscure and decorative glass for bathrooms and doors
- Toughened outer pane where safety glass is required

Before the glass is ordered
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
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.
Glazing rules in Wales
Safety glass in critical locations
In Wales, safety glazing is covered by Approved Document N (glazing) under the Welsh Building Regulations rather than Approved Document K. Glass in doors up to 1,500 mm above the floor, in panes within 300 mm of a door up to 1,500 mm, and in other glazing below 800 mm should be safety glass or protected. Laminated and toughened glass are the usual choices.
Listed buildings and conservation areas
Listed buildings in Wales need listed building consent from the local planning authority for works that affect their character, which can include replacing historic glass, glazing bars or sashes. Cadw advises on the historic environment in Wales. Reversible options such as secondary glazing are often easier to agree, but the council decides.

Security double-glazed units in Caerphilly: questions
Do you cover Risca as well as Caerphilly?
Yes. As well as Caerphilly, we can arrange surveys in nearby Risca, Pontypridd and Cardiff. 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.
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.
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.
