About Nanogel

Cabot Corporation created Nanogel in part to insulate thermally inefficient glazing systems. The feather-light aerogel is based on Cabot's patented surface modification and fine particle manufacturing technology. The nanoporous particles have an air content of 97% and weigh only

60-80 grams per liter, making Nanogel the lightest solid material in the world. It provides a superior combination of thermal and sound insulation as well as light transmission and diffusion over other insulation materials. These benefits offer new design solutions for architects where both maximum natural daylight levels and energy efficiency are required. Nanogel is manufactured exclusively by Cabot in Frankfurt, Germany.
