Sprayable fiberglass insulation

摘要

A type of (and method of making/spraying) sprayable fiberglass insulation is disclosed. Such sprayable insulation comprises: nodulated glass fibers containing glass fibers coated with polyacrylic glycerol (PAG) binder; and an adhesive to adhere the nodulated glass fibers together and to adhere the PAG binder on the glass fibers to a surface against which the sprayable glass insulation is sprayed. Optionally, such sprayable insulation can include a coloring agent and/or a biocide that adhere to said PAG binder. Such insulation can be applied by: combining the nodulated glass fibers and the adhesive into a composite stream; and spraying the composite stream onto a surface. The adhesive in the composite stream adheres the nodulated glass fibers together and adheres the PAG binder on the glass fibers to the surface against which the sprayable glass insulation is sprayed so as to form an insulation layer.
