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.

- Fixed within the reveal, leaving the original window untouched

Things to decide before you order
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
Rules that apply in Wales
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.
Replacing glass in an existing frame
Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.

Security secondary glazing in Penarth: questions
Can you survey in Penarth and nearby towns?
Yes. Surveys in Penarth, Cardiff and Barry 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.
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.
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.
