It leaves the original window untouched outside, which makes it a common choice for listed buildings, conservation areas and period sash windows.

How it opens

Frame colour and sightlines

Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.

Building regulations and safety in England

England

Planning permission

Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.

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 secondary glazing in Highbury: questions

Do you cover Islington as well as Highbury?

Yes. As well as Highbury, we can arrange surveys in nearby Islington, Holloway and Stamford Hill. Dates depend on installer availability.

Is secondary glazing safe for escape windows?

It can be, as long as it opens quickly from inside without a key. We design catches and handles for that.

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.
