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.

Before the glass is ordered

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.

Glazing rules in Wales

Wales

Security rules for new homes

Wales introduced its own Approved Document Q for new homes, in force from 1 November 2018, and it applies to newly erected dwellings only. It follows a similar approach to England's, with PAS 24 referenced for easily accessible doors and windows and laminated glass to BS EN 356 P1A in doors and nearby windows. It does not apply to changing the glass in an existing home.

Replacing glass in an existing frame

Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.

Security double-glazed units in South Glamorgan: questions

Which towns in South Glamorgan do you cover?

We can arrange work anywhere in South Glamorgan, including Cardiff, Barry, Penarth and Llantwit Major.

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.

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.
