How much should I budget for security window film in Barnet?
Budget £54 to £132 including VAT (£45 to £110 plus VAT) per m² for security window film in Barnet, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
Security window film is a clear, tough polyester film bonded to the inside face of existing glass with a strong adhesive. When the glass breaks, the film holds the fragments together, which reduces injury from flying glass and slows down anyone trying to get through, without replacing the glass itself.
What goes into security window film
- Edge-retention anchoring into the frame for blast mitigation
- Clear safety films from about 100 microns
- Blocks most UV light to slow fading
- Fitted on site without removing the glass
- Removable later without harming the glass
- Frosted and privacy versions for meeting rooms and bathrooms

What to think about first
Film or new glass
Where frames are being replaced or very high resistance is needed, laminated glass usually gives better value over its life than film.
Daylight application or anchored
A film applied to the visible glass is quickest. Anchoring it to the frame holds the whole pane in place and is the choice for blast mitigation.
Consents and safety: England
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Security window film in Barnet: questions
Can you survey in Barnet and nearby towns?
Yes. Surveys in Barnet, Potters Bar and Borehamwood are booked around installer availability.
Can film go on double glazing?
Often, but not always. Some units and coated glass can crack from heat build-up with certain films, so we check the glass type and the unit maker's guidance before fitting.
Can I still see through security film?
Yes. Security films are optically clear. Frosted and tinted versions are available where privacy or glare control is wanted.
Does security film make glass as strong as laminated glass?
Not usually. Film greatly improves how glass breaks and slows an attack, but it only matches a laminated glass class where that film and glass combination has been tested together.
