Bomb Blast Window Film

Bomb blast window film can save lives and protect property from flying glass in the event of an industrial explosion or a terrorist attack. Unfortunately this is a growing necessity to think about these events but in the unlikely even you will be affected, Guardian Window Film have you covered. Read on to find out how you can protect your buildings with blast protection films.


Selecting the correct and most protective blast protection specification for your specific threat is vitally important. Different types and levels of threat will require different window film solutions.

In the case of explosions, it is not possible to eliminate the risk,but we can help mitigate it, as It is possible to eliminate the potential risk from overhead glass.

The characteristics of a chemical explosion differ from those of a bomb blast. For example, blast duration from a petro chemical explosion is of a longer duration, than a small bomb close to a window. Bomb blast peak is instantaneous whereas vapour cloud is of a much longer duration and lower peak pressure.

This is depending on the amount of fuel. Certainly, the most important factor when determining the type of anti blast window film is best for you is the potential load of the explosion. For this, distances and charges should be taken into account.


A conventional daylight application of bomb blast window film to the inside of the glass, will often provide a sufficient level of protection and security. This can be enhanced by the application of silicone to bond all the glass edges to the window frame – if necessary. The thickness of bomb-blast protection film can be between 100 microns and 350 microns. This also depends on the area and thickness of the glass and the protection required.


The next level of protection would be a wetglaze application of window film to the inside of the glass. This wetglaze application is bonded onto the window frame, with a high performance Dow Corning 995 Silicone. Once again, the thickness of the bomb-blast protection window film can be between 100 microns & 350 microns. But this depends on the area and thickness of the glass and the protection required.


For even greater threats, there is a range of mechanical anchorage systems available. There are catching systems, restraint systems and clamping systems, all used in conjunction with the appropriate thickness of bomb-blast safety film. These systems can also be used to protect against the potential risk from overhead glass.

Visit our Mechanical Anchorage Systems page today for more detailed information on mechanical anchorage systems.


We will help you identify the risks in your specific case. We will then agree the level of bomb-blast protection you wish to achieve. From this, we can recommend the most effective security window film solutions using only products tested and approved to the relevant British, European and International Standards.
