Energy-Saving Insulation

An insulation material developed for NASA’s space shuttles can save energy here on Earth. Conventional insulation is placed between the structural beams of walls, called studs, but the studs themselves provide a conduit for heat to leak out. Adding Thermablok to the edges of the studs can increase the thermal insulation of a wall by 30 percent. The original material, an aerogel made of fragile silica, was treated with polyester fibers to boost its flexibility without compromising its thermal properties.
