Abstract
A type of (and method of making) fiberglass insulation is disclosed. Such insulation comprises: glass fibers; a polyacrylic glycerol (PAG) binder coating said glass fibers; and at least one of a coloring agent and a biocide adhered to said PAG binder. Such fiberglass insulation can take the form of a batt, board (a heated and compressed batt) or molding media (a different form of heated and compressed batt). The coloring agent and/or the biocide can be applied where the batt (or board or molding media, as the case may be) is manufactured or can be applied after the batt is installed in the field.
Claims23
Fiberglass insulation comprising:
- glass fibers;
- a polyacrylic glycerol (PAG) binder coating said glass fibers;
- at least one of a coloring agent and a biocide adhered to said PAG binder;
- wherein said glass fibers represent a first volume of glass fibers and said coloring agent is a first coloring agent and said first volume of glass fibers, said PAG binder and said first coloring agent define a first layer;
- and
- a second layer attached to said first layer, said second layer including a second volume of glass fibers and another binder applied to said glass fibers.
A method of making fiberglass insulation comprising:
- forming glass fibers into a pair of layers;
- applying a polyacrylic glycerol (PAG) binder coating to said glass fibers;
- and
- applying at least one of a coloring agent and a biocide that can adhere to said PAG binder.
A method of making fiberglass insulation comprising:
- forming glass fibers into a layer;
- applying a polyacrylic glycerol (PAG) binder coating to said glass fibers;
- and
- applying at least one of a coloring agent and a biocide that can adhere to said PAG binder, wherein said forming of said layer and said applying of PAG binder produce a white insulation product and said applying of coloring agent is carried out at least proximate to a site of installation of said insulation product rather than at a site of manufacture thereof.
