    Mats (blankets) made of high temperature wool are needled lightweight mats made of ceramic (ASW/RCF) high temperature wool (HTW) and provide an effective solution for a wide range of thermal insulation applications. They are characterized by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore do not generate smoke or fumes when exposed to heat. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.


    High temperature wool made of ceramic fibersalso known as ASW (Aluminum Silicate Wool) or RCF (Refractory Ceramic Fibre), have been used for years as the standard fibre type for insulation solutions up to 1425 °C.

    Morgan Thermal Ceramics

    Morgan's development of low biopersistence fibers has led to a revolution in the use of fibers for high temperature insulation applications over the last 20 years. Our patented Superwool products, manufactured using ISO 9002 certified processes, are made from alkaline earth silicate (AES) composition fibers uniquely engineered to provide benefits in high temperature insulation applications.
