PRODUCT TYPE
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.
MATERIAL
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.
Product Variations
Roll goods
Fiber mats are sold as roll goods as standard. The roll length depends on the selected thickness. As a standard width, we have 610mm wide rolls from stock. Double widths are available on request.

Cerachem™ has excellent chemical stability and is made from spun fibres called Cerachem™ ceramic fibres. The blankets have excellent dimensional stability before and after temperature application. They have excellent thermal insulation properties as well as very good acoustic insulation properties. The wide range of densities and thicknesses available allows for tailored thermal insulation in almost any application. Cerachem™ is suitable for classification temperatures up to 1425°C.
APPLICATION
- Excellent thermal insulation properties
- Resistant to most chemicals
- Excellent thermal stability
- Low heat storage
- Firm and at the same time elastic mats
- Resistance to thermal shock
- Good sound absorption
