Dow CorningÂ® Building Insulation Blanket is a new, thin, flexible insulation material that uses advanced silicon-based aerogel technology to deliver significantly improved thermal resistance vs. conventional insulation products.
Happily, your confusion and your concerns are mostly unnecessary. When insulations are compared, cellulose fiber insulation, a gray-white powder made from shredded recycled newspaper, emerges as the overall best choice. And where cellulose wonât work, there are other good, safe, products that can fill the gaps (literally). To understand why cellulose is the best insulation, compare it to its principal competitor, fiberglass. Cellulose and fiberglass together account for over 90 percent of insulation sales. Both insulations cost about the same, and both cost less than all their competitors.
