What is glass safety film for windows?

Glass is a fragile material which if not toughened or laminated, can pose a hazard.

Looking for spontaneous breakage film? It’s a similar glass film product and this page has all the information:

Spontaneous Breakage Film

Glass safety film is an adhesive polyester film that is bonded to glass and glazing in order to hold the glass together in the event of deliberate or accidental breakage. Various film thicknesses are available and they’re measured in microns or mil. Your architect may specify 100 micron safety film or 12 mil security window film.

See our technical brochures

Safety window film is subject to testing and certification to ensure it meets the required standards as set out by the British Standards Institution (BS 6206 (Class A, B & C) and the European Committee for Standardisation (En12600). The level of protection does vary for critical locations or in cases where the requirement is more robust for example, sports halls or glazing in playground areas.

Due to the benefits of security film for windows, it is used widely all over the world. It is available in a wide range of thicknesses, finishes and protection levels with the most popular being completely clear. Clear security film offers the same protection without altering the appearance of glass window.

Cost-effective window safety and security

Safety window film is a low-cost option compared to replacing glass, plus we have an extensive range of films offering different levels of protection, which means you can choose the right level of protection at the right cost for your business.

Which safety film thickness do I require?

The usual standard safety and security film is 4 mil thick, mil refers to one-thousandths of an inch and not millimetres. For example, 4 mil is 4/1000th” or 100 microns.  The 4 mil film is a basic safety film suitable for most architectural building structural requirements.

What thickness of window film is the best?

  • 4 mil safety film (100 micron)
  • 7 mil safety film (175 micron)
  • 8 mil safety film (200 micron)
  • 12 mil safety film (300 micron)

What are the benefits of fitting safety window film?

Let’s look a little closer at the benefits of installing safety window film.
When a higher level of protection is required, we have 7 mil (7/1000th”) or 175 microns thick safety film. The film is commonly referred to as bomb blast protection film and is used on glazing that could be affected by indirect shockwaves or light debris caused by an explosion. Nearly twice as thick as a 4 mil security window film thus giving twice the protection.

For extreme cases, we can offer a 12 mil (12/1000th”) or 300-micron film which offers blast protection. This bomb blast window film is designed to take the impact of a bomb blast. The level of protection comes from a combination of glazing frame strength, glass type and the 12 mil safety film combined.


Peace of mind against legal action
In these recent times of ‘claim culture’ is it vital that you protect your business and those around you from possible injury. It is also important that you avoid the threat of legal action that could result from a glass-related accident.

The application of safety window film will quickly and easily upgrade glass to meet safety film standards.

Minimise health and safety risks
The Workplace (Health Safety and Welfare) Regulation 14 came into force in 1996 and clearly recommends that every window should be protected against breakage to avoid risk or injury to buildings or visitors. Window film is considered to be as safe as laminated glass and can be retrofitted to ensure compliance.

Spontaneous Glass Breakage Due To Nickel Sulphide Inclusions.

Believe it or not this type of occurrence is quite common and can cause major disruption, not to mention injury in some cases. This type of dramatic event is usually caused by a phenomenon known as Nickel Sulphide Inclusions. Impurities within the glass react to changing weather or temperature conditions resulting in sudden fracture and consequent granulation of the glass often falling onto unsuspecting pedestrians below.

Help is at hand however from Lustalux with our range of fully tested Safety Window Films and Edge Retention Systems. Whether it be overhead, vertical glazing or glass spandrel panels we can render your glass safe in the event of spontaneous breakage.
