Abstract
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.
Claims7
A frangible fiberglass insulation batt comprises
- first and second longitudinally extending cured fiberglass strips separated by a longitudinally extending gap, each strip comprising cured glass fibers coated with a polymerized binder, and
- a longitudinally extending frangible polymerized binder bridge spanning the longitudinally extending gap and retaining the first and second longitudinally extending cured strips in side-by-side relation to one another, the bridge comprising polymerized binder and an insubstantial amount of glass fibers to cause the bridge to be characterized by internal bonds that are relatively weak in comparison to internal bonds associated with the glass fibers and polymerized binder comprising each of the first and second longitudinally extending cured fiberglass strips.
