Aerotherm’s aerogel nanotechnology thermal insulation is finding its way into outdoor apparel and footwear products where it can help protect wearers from extreme cold and extreme heat conditions.
Composed of over 90% air, aerogel materials were first used in industrial and National Aeronautics and Space Administration (NASA) applications, and are said to offer the lowest thermal conductivity of any solid.
Aerotherm uses silica aerogel to produce a strong, durable, and flexible material that is 2 to 8 times more effective than traditional thermal insulation, according to the company.
The insulation is thin, compression-resistant and waterproof – giving it ideal credentials for outdoor products, individual protective clothes and footwear. It is also durable in normal wash/dry cycles, the company says.
Unlike lofted fibrous insulation materials, which compress dramatically under pressure and lose their loft along with their insulating capacity, Aerotherm does not need loft to deliver its high insulation value and barely compresses, even in a foot bed under adult weight.
However, it can also be used in conjunction with lofted insulation in garments to enhance overall thermal performance.
Typically just 2mm thick layer of Aerotherm is enough for effective apparel insulation or 3mm thick layer of Aerotherm for footwear insulation.
Along with a growing roster of OEM developments with leading outdoor brands, the company has also launched Aerotherm Outdoor retail products including footwear insoles and gloves.
Targeted end products and components are footwear insoles, liners, uppers, tongue and toe caps; apparel including jackets and vests, elbow, shoulder, knee, seat, thigh and other key heat-loss and/or compression zones; and gear including gloves and seat pads.
In addition to its US headquarters and its South Korea plant, Aerotherm has a European headquarters in Russia, and a sales force in China to work with the factories in the region.
