How much do security double-glazed units cost in Whitehaven?
Guide prices for security double-glazed units in Whitehaven 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.

Things to decide before you order
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.
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 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 Whitehaven: questions
Do you cover Workington as well as Whitehaven?
Yes. As well as Whitehaven, we can arrange work in nearby Workington. 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.
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.
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.
