How much should I budget for security secondary glazing in Isle of Wight?
As a guide, security secondary glazing costs £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window. Because work in Isle of Wight is arranged individually, we confirm the full price, including any travel, in writing first.
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.
What you can specify
- Laminated glass in slim aluminium frames
- Noise and draught reduction
- Colour-matched frames to suit the room
- Low-E glass for better insulation
- Fixed within the reveal, leaving the original window untouched
- Vertical sliding, horizontal sliding, hinged and lift-out styles

What to think about first
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.
Consents and safety: 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 Isle of Wight: questions
Which towns in Isle of Wight do you cover?
Work across Isle of Wight is arranged individually because of travel and glass delivery, including in Newport, Ryde, Cowes and Sandown. Send your postcode and we will confirm what is possible.
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.
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.
