Abstract
An apparatus and a method are provided to retain loose fill or particulate insulation between the outer and inner walls of a structure. The apparatus comprises a barrier assembly comprised of laminate layers of a netting material and a polypropylene material both with some degree of flexibility. The netting material is constructed to strengthen the polypropylene material and bulge slightly when a desired amount of insulation has been received and positioned within an enclosed space of the wall structure. The polypropylene material is constructed to be substantially air permeable but substantially impermeable to the passage of all size fractions of insulating fibers and other particulates typically found in insulation materials.
Claims11
A method for placing loose fill insulation in a support frame of a building in which the insulation includes fibers having fiber portions, comprising:
- forming a support frame for receiving loose fill insulation;
- providing filter means including a plurality of fibers joined together using heat to define a fabric wherein said fabric is a light, thin material having by itself insufficient strength to hold the loose fill insulation in said support frame, said filter means having first sized passages for controlling the passage of fiber portions therethrough and permitting passage of air;
- providing netting means having a plurality of netting holes with said netting holes having second sized passages greater than said first sized passages of said filter means wherein at least some of said first sized passages overlie said second sized passages, said netting means being made separately from said filter means with said netting means connected to said filter means to define barrier means;
- attaching said barrier means to said support frame;
- forming at least a first access hole in said barrier means;
- feeding the loose fill insulation between said barrier means and a portion of said support frame using said first access hole;
- permitting air to escape through said barrier means preventing substantially the escape of fiber portions of the loose fill insulation through said barrier means using said filter means;
- observing that a sufficient amount of loose fill insulation has been fed between said barrier means and said portion of said support frame;
- and
- discontinuing said feeding of the loose fill insulation.
An apparatus for providing loose fill insulation in a building in which the insulation includes fibers having fiber portions, comprising:
- a support frame;
- and
- barrier means connected to said support frame for use in containing loose fill insulation including fibers and portions thereof, said barrier means including filter means that is air permeable and substantially impermeable to the passage of substantially all portions of the insulation fibers, said filter means having first sized passages for controlling the passage of fiber portions therethrough and permitting the escape of air and said barrier means including netting means that includes netting holes, said netting holes having second sized passages greater than said first sized passages of said filter means, said netting means providing strength to said filter means, said filter means being made of a fabric wherein said fabric is a light, thin material having insufficient strength by itself to hold the loose fill insulation, portions of said filter means having said first sized passages overlying said netting means holes having said second sized passages wherein said first sized passages are able to prevent escape of fiber portions that are able to pass through said second sized passages, said netting means being made separately from said filter means but being connected thereto, at least a first access hole also being provided in said barrier means.
