1. A molding based on a monolithic organic aerogel, having a density in the range from 60 to 300 kg/m3, and a thermal conductivity in the range from 12 to 17.8 mW/m*K, measured according to DIN EN 12667:2001-05 at 10° C. and 101,325 Pa, and
wherein the molding comprises 40 to 80 vol.-% of pores with a diameter of less than 150 nm, 21 to 75 vol.-% of pores with a diameter of less than 27 nm, based on a total pore volume; wherein the fraction of pores with diameter of 150 nm and higher is 20-60 vol %;
wherein the molding is in the form of a sheet with a thickness in the range from 100 μm to 10 mm; and
wherein the monolithic organic aerogel is based on polyurethane, polyurea or polyisocyanurate or mixtures thereof.
