Escape and ventilation

On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.

What the rules say in Wales

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.

Planning permission

In Wales the local planning authority decides whether a new or altered shopfront needs planning permission. Replacing glass in an existing frame usually does not, because the outside of the building looks much the same. Bollards or barriers on the pavement need consent from the highway authority, normally the council.

Security secondary glazing in Merthyr Tydfil: questions

Which areas near Merthyr Tydfil do you cover?

We can arrange work in Merthyr Tydfil and in nearby Aberdare (4 miles), Rhondda (7 miles) and Ebbw Vale (8 miles). Dates depend on installer availability.

Can I still open my sash windows?

Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.

Does secondary glazing reduce noise?

Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.

Do I need permission for secondary glazing in a listed building?

It depends on the building and the council. Internal secondary glazing usually has less impact than replacement windows, but listed building consent may still be needed. Ask the conservation officer before ordering.
