Security secondary glazing in Portishead

What is the price of security secondary glazing in Portishead?

As a guide, allow £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in Portishead, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free survey.

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
Suits sash, casement and arched openings
Laminated glass in slim aluminium frames

Escape and ventilation

On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.

Building regulations and safety in England

England

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.

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.

Security secondary glazing in Portishead: questions

Which areas near Portishead do you cover?

We can arrange work in Portishead and in nearby Nailsea (3 miles), Clevedon (5 miles) and Bristol (8 miles). Dates depend on installer availability.

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.

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.
