    Mats (blankets) made of high temperature wool are needled lightweight mats made of biosoluble (AES) 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.


    Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers, which are melted and then rapidly solidified using a combination of silica SiO2 and calcium oxide (CaO) with magnesium oxide (MgO) can be produced.

    Superwool® Plus Blankets offer the same benefits as the other products in the Superwool fibre family, but with improved handling strength and optimised thermal properties. Superwool® Plus Blankets are produced from pure raw materials using a new manufacturing technique. In addition to the optimized thermal properties, the larger nuisance dust particles have been effectively eliminated, making the product soft to the touch and less irritating to the skin during use. Superwool® Plus Blankets are made from long Superwool® Plus fibres. Superwool® Plus Blankets have excellent thermal stability and retain their original soft fibrous structure up to the maximum continuous use temperature. Superwool® Plus Blankets are needled from both sides and exhibit high strength both before and after heating. Superwool® Plus Blankets contain no binder or lubricant and do not emit fumes or odor when first heated. Superwool® Plus Blankets are pliable, easy to cut and shape, and easy to install. (CAS number: 329211-92-9).
