The invention relates to an insulation product formed from at least two insulating layers containing aerogels, each of said layers comprising from 25 to 95 wt % of aerogel(s) and from 5 to 75 wt % of fibers, said insulating layers being joined together by means of an organic adhesive, advantageously aqueous, based on vinyl polymer(s). The invention also relates to a method for obtaining said product.

High-performance thermal insulation products

The manufacture of a thermal insulating product whereby a foam is produced from a mixture of mineral particles, the product is shaped, and the foam is dried. Specifically, the foam is produced from a crystallized calcic part and a crystallized magnesian part, and a composite aggregate of the crystals of the calcic and magnesian part is formed. The calcic part is chosen from calcite and/or aragonite, and the magnesian part is made of hydromagnesite.

High performance thermal insulation products

The present invention relates to a heat-insulating material, in particular in the form of a solid foam, based on mineral particles of submicron porosity, this material incorporating two different ranges of porosities, advantageously including a first range consisting of (macro)pores with diameters of between 10 microns and 3 mm, and a second range consisting of submicron pores with diameters greater than 4 nm and less than 1 &#x3bc;m, the pore volume of said submicron pores being at least 0.5 cm/g and the mass per unit volume of said insulating material being less than 300 kg/m.

High-performance heat-insulating materials

A thermal insulation product based on mineral wool, characterized in that the fibers have a micronaire of less than 10 l/min, preferably less than 7 l/min and especially between 3 and 6 l/min, the product including infrared absorbent and/or reflective elements, and in that the product has a thermal conductivity of less than 30 mW/m.K.
