830 - Square

The 830 Square assembly provides excellent protection during flashovers, (when the outershell is exposed to high temperatures, the fabric thickens instantly, creating additional air space and thus improving the protection of the firefighter.) In addition, this assembly provides thermal insulation and a significant reduction of heat stress. At the same time, it is waterproof, breathable and comfortable. It was especially designed for the Fire Brigade of Paris. This innovative product protects every BSPP firefighter on a daily basis.

Outer fabric Square

The innovation of the Square fabric lies in its construction and in the choice of raw materials.

Its original dual structure combines the advantages of a Meta Aramid front side and a Para Aramid back side, creating a surface capable of reacting to heat flows.

Indeed, in the event of a flashover, the fabric will thicken instantly, creating additional air space and thus improving the protection of the firefighter.

Para aramid provides a very high mechanical resistance (tensile and tear strength); placed on the inside, it is protected from UV rays, which allows the fabric to retain its properties over time.

The Square also has a very high air permeability, which allows for a better ventilation and it helps to reduce the firefighters' heat stress.

Moisture barrier SIO-A.I.R. PTFE

100% aramid

Following their risk assessment, firemen sometimes demand that the membrane is not only breathable, but also very heat resistant. That is why we developed our own solution: the SIO-A.I.R barrier PTFE. We have laminated a base layer of PTFE on a 3D felt of 100% aramid.

The SIO-A.I.R barrier PTFE is tested in accordance with the ISO 6530 standard (Protection against liquid chemicals - Test method for resistance of materials to penetration by liquids). It is waterproof, with a water column of more than 10 meters, even after it has been exposed to a temperature of 220°C for 7 seconds. It also passes the kerosene test.

Finally, the membrane also passes the ASTM F1671 test after 25 washes at 60°C, which ensures that a selection of viruses cannot penetrate the SIO-A.I.R barrier PTFE membrane.

Thermal barrier Techweave

This 3D weave produces a fabric with excellent insulating properties.

The air channel system thus created makes it possible to achieve a level of thermal insulation never before achieved while improving the regulation of heat and sweat that firefighters generate while in interventions. Thanks to its aramid composition, this lining has a very good mechanical resistance.

This fabric improves the comfort of the firefighter thanks to its flexibility and lightness.

50% of Techweave is in direct contact with the skin, which makes Techweave very comfortable.
