Typically, heavy and thick turnout gear helps provide a high thermal protective performance (TPP). Unfortunately that contributes to heat stress, by not allowing enough total heat loss (THL). As an industry, we have been trained to think that you have to sacrifice TPP in order to achieve maximum THL. We are offering a solution contrary to that conventional thinking.
Fire-Dex offers the most lightweight, thin, and flexible fabric composites with the highest THL ever seen in the fire service…without sacrificing thermal protection or durability. Introducing TECGEN71, an exclusive outer shell available in Fire-Dex Ultimate turnout gear.
TECGEN71 features rip twill construction that puts the proven strength of 60/40 Kevlar®/Nomex® on the face of the fabric, while creating a super structure of the TECGEN® fiber inside.
What is TPP and THL?
From the U.S. Department of Homeland Security and FEMA, thermal protective performance (TPP) “measures how well a fabric protects the wearer against second-degree burns in a flash fire. The higher the TPP value, the more thermal protection the fabric provides relative to other fabrics.”
Total Heat Loss (THL) measures breathability, or the ability of the total composite system to allow heat and moisture to evaporate. Breathability is a key factor in reducing heat stress.
Most turnout gear options focus on TPP or reducing the weight as it is difficult to attain both measurements. TECGEN71 is different. The lighter weight total composite system allows more breathability and flexibility, yielding a 48% higher THL without sacrificing TPP or durability.
