Production of Thermal Insulation Products

摘要: Methods of making thermal insulation products are provided, one method including the steps sealing a support material (e.g., nanoporous core such as fumed silica, an aerogel powder, etc.) and at least vapor steam) within interior portion substantially gas-impermeable envelope metallic and/or polymeric film), then condensing after step to reduce pressure from first before lower second condensing. The disclosed methods limit or eliminate need for mechanism pumping mechanisms drawing vacuum products, drying sealing, like.
