What should security double-glazed units cost in Lerwick?
As a guide, security double-glazed units costs £174 to £594 including VAT (£145 to £495 plus VAT) per unit. Because work in Lerwick is arranged individually, we confirm the full price, including any travel, in writing first.
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
- Security glazing tape or clips where beads are external
- Low-E coating and argon fill for insulation
- Toughened outer pane where safety glass is required
- 24 mm, 28 mm and other overall thicknesses to suit frames
- Warm-edge spacer bars in black, grey or white
- Made to measure for each sash, light and door panel

The island groups have small stone-built towns such as Kirkwall, Lerwick and Stornoway and scattered rural properties, with exposed weather and ferry freight for every glass delivery.
Good candidates for security double-glazed units:
- Glazed back and side doors
- Ground-floor and basement windows
- Windows in flats on walkways and balconies
- Patio doors and bifolds
Before the glass is ordered
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.
Which pane is laminated
Laminating the inner pane is the usual security choice. Laminating both panes adds protection on high-risk elevations.
Glazing rules in Scotland
Replacing glass in an existing frame
In Scotland, replacing glass in an existing frame is normally treated as a repair rather than work needing a building warrant. Whether replacing whole windows or doors needs a warrant depends on the building, and the work should still meet the building standards. The council's building standards service can confirm what applies.
Security rules for new homes
Standard 4.13 asks for doors and windows in new homes that are vulnerable to unlawful entry to be secure. Glazing that would let someone reach a lock from outside should be laminated or similarly robust, and easily accessible openable windows need a keyed lock or a keyless lock with laminated glass. It applies through the building warrant for new homes and conversions.

Security double-glazed units in Lerwick: questions
Can you work in Lerwick?
Work in Lerwick is arranged individually because of travel. Send your postcode and details and we will confirm what is possible.
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.
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.
