Misted unit replacement means swapping a double-glazed unit whose seal has failed, so moisture has got between the panes, for a new sealed unit. Doing it with a laminated pane turns a routine repair into a security upgrade for little extra cost.

- Toughened panes where safety glass is required
- Laminated inner pane for security

A laminated inner pane adds security for a small extra cost while the unit is being made.
Replace the frame instead

Rules that apply in Northern Ireland
Replacing glass in an existing frame
Building regulations in Northern Ireland are administered by the eleven councils' building control services. Replacing only the glass in an existing frame is generally treated as a repair, while replacing whole windows or doors can be controlled work, so check with building control first. New glass in a critical location should be safety glass under Part V.
Safety glass in critical locations
In Northern Ireland, safety glazing is covered by Part V of the Building Regulations (Northern Ireland) 2012, with guidance in Technical Booklet V. It follows a critical-location approach similar to Great Britain, covering glazing in and beside doors and at low level. Laminated or toughened safety glass is the usual answer; building control at the council can confirm the detail.

Misted unit replacement with laminated glass in Derry: questions
Do you cover Strabane as well as Derry?
Yes. As well as Derry, we can arrange work in nearby Strabane. Dates depend on installer availability.
Why is there condensation between my window panes?
The seal around the unit has failed, letting damp air into the gap. The only lasting fix is a new unit.
Do I need a new window frame?
No, if the frame is sound. We replace only the sealed unit.
Can misted glass be repaired instead of replaced?
Some services drill and dry units, but the seal stays broken and insulation is not restored. A new unit is the reliable fix.
