SECURABLINDS – Manual Attack and Blast Blinds

SECURABLINDS Attack and Blast Blinds provide total protection against forced entry and blast attacks.

SECURABLINDS are constructed of a unique blade design to provide a high level of protection against attacks of up to 500kg of TNT.

Upon receiving the forward force of an attack or blast, the SECURABLINDS are triggered to close and the attack or blast is absorbed by the blind, protecting the staff and assets safely inside the building behind a secure barrier.

SECURABLINDS can be retrofitted to an existing building’s doors and windows, as well as installed into new build applications. A range of configurations are available with three product specifications offering different resistance levels.

18 years of development and blast testing have culminated in an exact production specification for SECURABLINDS, increasing strength and integrity during the steel bending and welding manufacturing stages.

Technical Information

SECURABLINDS unique patented design achieves unparalleled resilience and blast absorption in attack scenarios.

The manufacturing methods adhere to ISO 9001:2008 building core strength and durability throughout every aspect of construction.

The blades are extruded to the patent protected design for inherent strength. They are further reinforced with high tensile steel rods when fastened to the inner frame.

The robust fastening methods and technologies guarantee high pressure blast absorption and controlled deflection properties.


SECURABLINDS provide two types of protection, against manual attack and blast attack.

SECURABLINDS patented portfolio achieved ISO16933 and has also been accredited by the American Department of State (DOS) for prevention of forced entry.

2 SECURABLINDS products are certified by CPNI (Centre for the Protection of National Infrastructure) blast testing. They managed to achieve the following ratings:

  • Low Hazard
  • Minimal Hazard
  • No Hazard

All tested is carried out without any window or frame in front of the product so actual ingress times would be above those achieved in any testing.

Blast Blinds have been tested to and achieved the standards:

  • 100kg of TNT Equivalent @ 33m – Minimal Hazard
  • 100Kg of TNT Equivalent @ 25m – Low Hazard
  • 500kg of TNT Equivalent @ 28m – No/Minimal/Low Hazard

Comblast testing authority have accredited the SECURABLINDS Blast Blinds for protection against 100kg and 500kg TNT Equivalent.


The SECURABLINDS blade design closes the blind instantly in a blast scenario when triggered by the blast wave.

The blades are extruded for inherent strength and the blade profile distributes blast pressure evenly across its section.

The overlapping closed blades dissipate the blast pressure across the entire blind towards its four corners – the strongest fixing points.


The SECURABLINDS outer frame is custom manufactured with the corresponding number of fastening points dictated by a ‘pull test’ carried out on every building to determine the frame requirements.

Where a building substrate has insufficient strength, a ‘reinforcing profile’ is installed between the upper concrete slab and the lower floor slab. Secure Walling in the form of Bullet Resistant Partitioning is also available.

Reinforcing in this manner enables each blind to be secured through the reinforcing profile and be bolted to the adjacent blind.


SECURABLINDS are bespoke manufactured to fit the requirement of each project, with a variety of different options available.


SECURABLINDS have been adopted in a number of teaching environments, including schools, primary and secondary, in addition to specialist and religious schools with high protection requirements.

Bank and Building Societies

In the private sector, SECURABLINDS have been installed into a range of London and nationwide banking headquarters, in addition to high street branches.

Data Cemtres

SECURABLINDS are ideal for data centres, providing a high level of protection with a discreet aesthetic.
