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.

Things to decide before you order
Listed building consent
Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Rules that apply in Scotland
Replacing glass in an existing frame
In Scotland, replacing glass in an existing frame is normally treated as a repair rather than work needing a building warrant. Whether replacing whole windows or doors needs a warrant depends on the building, and the work should still meet the building standards. The council's building standards service can confirm what applies.
Planning permission
Under the Scottish planning system the council decides whether a new or altered shopfront needs planning permission; changing the glass in an existing frame usually does not. Bollards or barriers in a road or footway need consent from the roads authority, which is normally the council.

Security secondary glazing in Forth Valley: questions
Which towns in Forth Valley do you cover?
We can arrange work anywhere in Forth Valley, including Stirling, Falkirk, Alloa and Grangemouth.
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.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
