Environmental Testing

Environmental Testing

We test SHEERGARD® in the world's most extreme environments. It stands strong in wind, dust, solar radiation, ice, and snow.

With 40 years of experience using PTFE to coat structural fabrics, our SHEERGARD® team has tested its resilience against the most challenging conditions from sub-zero to searing heat. This is why demanding clients like first responders and the US military trust us.

Service Details

SHEERGARD® PTFE-coated fabrics have been rigorously tested for structural applications in all environmental conditions. Analysis proves they perform in winds over 210 mph (340 km/h), temperatures ranging from -58°F to +210°F (-50°C to +100°C), and have no leakage in rain rates over 5.9 in/hr (150 mm/hr). Sheergard can also handle 70 PSF (340 kg/m2) of snow, MIL-STD-810G ice, and 31/2 inch (90mm) hail balls at 150 mph (245 km/h). It also offers MIL-STD-810G durability for fungus, sand and dust, solar radiation, and salt fog. Continual testing and analysis mean that you can be confident that SHEEERGARD® always delivers high performance and protection – wherever and however you put it to work in the world.

Rigorous testing standards

Saint-Gobain Composite Solutions rigorously tests all SHEERGARD® radome products via software-modeled analytics, lab-scale material characterization, and most importantly, directly relevant application testing. Every SHEERGARD® radome complies with strict MIL.STD.810 testing – the military-leading standard for all environmental conditions including temperature, humidity, salt, fungus, and many more. Software modeling such as Finite Element Analysis and Thermal Analysis can yield information on deflections, factors of safety, and thermal management requirements. Application tests such as physical hail storm testing, destructive fabric testing, and real-life application exposure reveal key learnings in creating a truly optimized product. Our testing begins during the co-development process to develop relevant tests and gather data that allows us to create market-ready solutions quickly.
