How much do security double-glazed units cost in Holyhead?
Guide prices for security double-glazed units in Holyhead are £174 to £594 including VAT (£145 to £495 plus VAT) per unit for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.
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.
Glass and fitting options
- Obscure and decorative glass for bathrooms and doors
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Warm-edge spacer bars in black, grey or white

Things to decide before you order
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.
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.
Rules that apply in Wales
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.
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.

Security double-glazed units in Holyhead: questions
Do you cover Caernarfon as well as Holyhead?
Yes. As well as Holyhead, we can arrange work in nearby Caernarfon. 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.
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.
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.
