Security secondary glazing in Morden

Security secondary glazing in Morden: what will it cost?

Budget £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in Morden, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.

Security secondary glazing is a separate slim window fitted on the room side of an existing window, glazed with laminated glass so it forms a second barrier. It leaves the original window untouched outside, which makes it a common choice for listed buildings, conservation areas and period sash windows.

Getting the right glass for your building

Listed building consent

Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.

How it opens

Match the opening style to the original window so both can be opened, cleaned and used for ventilation.

What the rules say in England

England

Windows needed for escape

Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.

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.

Security secondary glazing in Morden: questions

Can you survey in Morden and nearby towns?

Yes. Surveys in Morden, Mitcham and Wimbledon are booked around installer availability.

Does secondary glazing reduce noise?

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

Can I still open my sash windows?

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

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.
