Aerotherm is produced using Aspen Aerogels aerogel insulation products. The original Aspen Aerogels material is processed to obtain 2-5 mm thin isolation panels. The material is encapsulated in a thin membrane to prevent leakage of aerogel. Aerotherm insulation material can be cut out according to a customer’s design. Aerogel Technologies has also introduced universal panels for use in apparel and footwear applications.
