Patent ID: 7252868

Claim:
A batt insulation product comprising: first and second insulation layers coupled together to form a batt, each insulation layer containing randomly oriented fibers bonded together by a binder, each insulation layer having first and second major surfaces and a pair of side portions; and at least one prefabricated flexible reinforcing non-woven layer comprising randomly oriented glass fibers disposed between said insulation layers and extending along a length of said batt, said at least one reinforcing layer being directly bonded to a respective major surface of each of said insulation layers and forming a bond located in between the respective major surfaces of said insulation layers along said respective major surfaces, wherein the thickness of each of said insulation layers is substantially greater than the thickness of said reinforcing layer, wherein said batt comprises a plurality of said flexible reinforcing non-woven layers disposed between said first and second insulation layers and extending along the length of said batt, wherein said plurality of reinforcing non-woven layers comprises at least two reinforcing layers disposed substantially parallel to said major surfaces and each other, and wherein said at least two reinforcing non-woven layers comprises at least two reinforcing layers disposed substantially parallel to said major surfaces and each other, and wherein said at least two reinforcing non-woven layers are coupled together along respective faces in between the insulation layers, whereby said insulation product is separable at an interface of said at least two reinforcing non-woven layers to form at least two insulation products.
