Tensotherm is ideal where significant acoustic dampening is desired or required. The product can block out the sound of a jet taking off, or hold the sound of rock concert inside. The product’s sound attenuation ability is due to its Nanogel aerogel core and interior PTFE-coated acoustical membrane liner. It consists of Cabot’s Nanogel aerogel sandwiched between two layers of structural PTFE fiberglass membrane. This creates an insulated, energy-efficient inner layer that maintains translucency and promotes natural daylighting. The fabric is less than 50 mm thick, yet it more than quadruples the thermal insulation performance with a value of R-12 and natural light transmission value of 3.5 percent. This durable, fade resistant material also offers maximum moisture control and superior sound insulation. These performance features are permanent, so they will not change over time.
