Our 868 Twin solution meets the highest requirements in terms of protection against convective and radiant heat. This four-layer assembly thus offers a rarely matched level of protection while remaining light and flexible. The materials used have shown, over years of continuous use by many firefighters, their efficiency and resistance.
The Twin fabric has a specific two-sided construction. The Twin has a long life span and a good mechanical resistance: it doesn't break open after a flashover. This fabric is used daily by many firefighters worldwide, its high performance is well‑established.
The used mesh is 100% aramid. The construction’s advantages are a large air layer, its lightness combined with great flexibility, as it is stretchable. This type of material is mechanically very resistant, which is a key element for firefighters.
Following their risk assessment, firemen sometimes ask for a membrane that 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 metres, even after it has been exposed to a temperature of 220°C for 7 seconds. It also passes the kerosene exposure 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.
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.
