CASSMAT - a new biomineral-based insulation material

CASSMAT is a biomineral-based insulation foam that has a thermal conductivity of 0.035 W/mK which is similar to other competitors.

A major advantage of CASSMAT is a lower carbon footprint in manufacturing of about 0.35 tonne CO2-eq./t of biobased fibres compared to 2.72 tonne CO2-eq./t of glass fibres. At a production of 80,000 t per year of CASSMAT, this equates to a reduction of 0.2 million tonne CO2-eq. per year. The energy consumption for electric melting of glass is 1100kWh/t finished product.

Cellulose insulation is about 10 times less energy.

The annual contribution to the energy system will be a saving of 0.08TWh, giving CASSMAT a much more energy efficient and lower carbon footprint manufacturing process, significantly contribute to a sustainable energy system.

The global insulation market size is estimated to grow to €52 billion by 2035 and CASSMAT aims to control 0.2% of that global market share with an estimated value of €800 million annual turnover.
