What is the price of security double-glazed units in Penarth?
Our guide range for security double-glazed units in Penarth is £174 to £594 including VAT (£145 to £495 plus VAT) per unit, including fitting. The survey is free for new installations and your fixed price follows in writing.
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 goes into security double-glazed units
- Made to measure for each sash, light and door panel
- Toughened outer pane where safety glass is required
- 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

Questions we will ask at the survey
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
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.
Building regulations and safety in Wales
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 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.

Security double-glazed units in Penarth: questions
Can you survey in Penarth and nearby towns?
Yes. Surveys in Penarth, Cardiff and Barry are booked around installer availability.
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.
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.
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.
