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
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
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
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.
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 Gwent: questions
Which towns in Gwent do you cover?
We can arrange work anywhere in Gwent, including Newport, Cwmbran, Pontypool, Ebbw Vale and Risca, and in other towns across the area.
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.
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.
