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
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
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 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.
Windows needed for escape
Approved Document B for Wales sets out escape window provisions for homes broadly in line with England's, including minimum clear opening sizes and a maximum sill height. New glass does not change those, but locks, secondary glazing and film must leave an escape window able to open. Laminated glass is not designed to be broken out.

Security secondary glazing in Chepstow: questions
Do you cover Monmouth as well as Chepstow?
Yes. As well as Chepstow, we can arrange surveys in nearby Monmouth, Newport and Cwmbran. Dates depend on installer availability.
Will secondary glazing cause condensation?
A well-fitted unit usually reduces condensation on the inner pane. Some ventilation of the gap may be needed, which we discuss at the survey.
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.
