Abstract
Fibrous insulation products manufactured with surfactants and methods for making are disclosed. The surfactant may be neutral or charged and, if charged, may be anionic, cationic or zwitterionic, although neutral or non-ionic provide suitable results. The surfactant may be of any chemical structure class, although ethoxylated alcohols and ethoxylated ethers have been found most suitable. Surfactant may be sprayed onto mineral fibers as a separate dispersion or as part of a binder dispersion. The surfactant my optionally be used with an organo-silane coupling agent, such as an amino-silane.
