Security double-glazed units in Dorchester

What is the price of security double-glazed units in Dorchester?

Guide prices for security double-glazed units in Dorchester 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.

Questions we will ask at the survey

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.

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 England

England

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.

Replacing glass in an existing frame

Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Security double-glazed units in Dorchester: questions

Can you survey in Dorchester and nearby towns?

Yes. Surveys in Dorchester, Weymouth and Bridport are booked around installer availability.

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.

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.

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.
