Blast Protection

The concept of SECURABLINDS® design is proven in rigorous attack and blast testing. The closing of the blind is triggered by the forward force of the blast wave and then the blast is absorbed by the blind, protecting the occupants and contents of the building. The SECURABLINDS® range of products can be retrofitted to existing buildings as well as new build applications.

Blast Blinds Test

A blast occurs radiating out a pressure wave in all directions.

The pressure wave smashes the window forcing the glass and anti-shatter film or polycarbonate trigger to automatically shut the blinds.

The SECURABLINDS® Blast Blind then absorbs the force of the pressure wave, stopping glass shrapnel and other blast debris from entering the building.

The negative phase of the blast wave then draws the glass and debris back towards the blast source.


SECURABLINDS® security systems have constantly been subjected to numerous blast trials since 2000. Specific testing and product development since 2013 has delivered a significant step forward in the level of protection the SECURABLINDS® Blast Blind offers. A blast can be unpredictable so the latest rigorous testing and development has been key to achieving the level of protection that the SECURABLINDS® Blast Blinds offer.

The SECURABLINDS® Blast Blinds have been tested to achieve rigourous standards.

The integrity of the SECURABLINDS® Blast Blinds in a real live blast scenario is the priority. That is why blast testing of the SECURABLINDS® product range is carried out by the following independent organisations:

Comblast offers blast testing to internationally recognised standards.

"In terms of competitive advantage, there is nothing else on the explosion protection market similar to the security blind other than primary or secondary blast rated window systems, which do not have the same ability to absorb pressure as the security blind does through rapid and controlled deflection."

“We have no hesitation in recommending the products offered by SECURABLINDS Limited based on the evidence of blast performance that we have witnessed in the course of the multiple blast trials on a range of different test specimens and styles.”
