Insulation configurations for the ceiling, floor and walls of structures, which include in a first embodiment, at least one layer of particulate or "blown" insulation with a water vapor-permeable film or films isolating the layer or layers to limit air circulation and infiltration through the layers. In another embodiment, sheets of a moisture vapor-permeable film membrane are provided in association with insulating "batts" or rolled sheet, fibrous, non-solid insulation to divide the insulation into discrete layers and limit air infiltration through the layers. A method for increasing the efficiency of insulating material in structures, which includes providing one or more moisture or water vapor-permeable membrane films or membranes in association with the insulating material to isolate the insulation in discrete layers and limit air infiltration and circulation through the layers.
An insulation configuration for attic floors comprising a layer of non-solid insulation material adjacent said attic floor and at least one moisture vapor-permeable film means positioned horizontally over said insulation material and exposed to the air, whereby air circulation into said insulation material from the attic is reduced.
An insulation configuration for floors in structures comprising a layer of insulating material located adjacent the underside of the floor and at least one moisture vapor-permeable film means positioned horizontally under said insulating material and exposed to the air, whereby circulation of air into said insulating material from the airspace beneath the floor is reduced.
A method for increasing the efficiency of a non-solid insulation layer adjacent the floor of an attic comprising installing at least one sheet of moisture-vapor permeable film horizontally over said insulation layer and exposed to the air in the attic, to reduce air circulation into said insulation.
A method for increasing the efficiency of non-solid insulation layer adjacent the underside of the floor of a structure comprising installing at least one sheet of moisture-vapor permeable film horizontally under said insulation layer and exposed to the air beneath the floor, to reduce air circulation into said insulation from the airspace beneath the floor.
