Frangible fiberglass insulation batts

摘要

A frangible fiberglass insulation batt includes a pair of fiberglass strips arranged to lie in side-by-side relation to one another and a frangible polymerized binder bridge spanning a gap between the fiberglass strips and retaining the fiberglass strips in side-by-side relation. To produce such a batt, a stream of uncured fiberglass insulation is cut along its length to form two side-by-side fiberglass strips and then passed through a curing oven to cause heat generated in the oven to polymerize (cure) binder associated with the strips in the gap to form the frangible polymerized binder bridge.
