Nanogel, Kallwall

Kalwall with Nanogel translucent aerogel combines R-20 insulation with 20 percent light transmission; doubles light transmission and thermal insulation over current technologies; and is resistant to condensation, mold, and mildew. The 2-3/4-inch-thick fiberglass-reinforced polyester panels yield constant insulating properties over time and offer improved acoustical properties. Nanogel is a highly porous form of silica aerogel that is 97 percent air.
