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.

- Fitted on site without removing the glass
- Security films of 200 microns and thicker
- Removable later without harming the glass
- Thermal-stress check on sealed units and coated glass

Before the glass is ordered
Safety or security film
Thinner films improve how glass breaks; thicker films add resistance to attack. We match the film to what you want it to do.
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.
Glazing rules in Northern Ireland
Listed buildings and conservation areas
Listed buildings in Northern Ireland need listed building consent from the council for works affecting their character, which can include historic glass and sash windows. The Department for Communities' Historic Environment Division advises on these cases. Conservation areas bring extra scrutiny of shopfronts and external changes.
Replacing glass in an existing frame
Building regulations in Northern Ireland are administered by the eleven councils' building control services. Replacing only the glass in an existing frame is generally treated as a repair, while replacing whole windows or doors can be controlled work, so check with building control first. New glass in a critical location should be safety glass under Part V.

Security window film in County Londonderry: questions
Which towns in County Londonderry do you cover?
We can arrange work anywhere in County Londonderry, including Coleraine, Derry, Limavady and Magherafelt.
How long does window film last?
Fitted on the inside, quality films typically last many years. Life depends on sun exposure and cleaning, and we give the manufacturer's expected life with the quote.
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.
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.
