Abstract: A dynamic heat flow meter is provided which introduces a measured air flow into the system adjacent the test sample (e.g., insulation product), for which thermal properties are to be measured. The heat flow meter then measures thermal properties (e.g., thermal conductivity and/or heat capacity) of the test sample taking into account air flow through and/or adjacent the test sample.

Abstract: A method and/or system is provided that compensates for the flow of air through fiberglass insulation. In certain example embodiments, a dynamic heat flow meter or the like is provided for measuring and/or determining any detrimental effects of air flow through insulation such as fiberglass insulation. Once the possible detrimental effects are recognized, an insulation system is adapted (e.g., by providing a foam based insulation in a wall cavity in addition to the fiberglass insulation) to compensate, or substantially compensate, for the effects of air flow through the fiberglass. For instance, a sufficient amount of foam insulation may be provided in a cavity adjacent fiberglass, where the foam blocks or substantially blocks air from flowing through the cavity, thereby compensating for the effects of air flow through fiberglass and permitting the intended R-value to be maintained or substantially maintained.

Abstract: Certain example embodiments of this invention relate to insulation (e.g., loose-fill insulation which may be blown into attics, wall cavities, or the like) including a mixture of fiberglass and cellulose. In certain example embodiments, the insulation mixture comprises from 15-60% cellulose, more preferably from 20-50% cellulose, and most preferably from 25-45% cellulose (with substantially the remainder of the insulation be made up of fiberglass). Example advantages include improved radiant barrier properties and thus improve R-values/inch.

Abstract: An insulation batt with vapor retarder is adapted to be friction-fit installed in cavities such as vertically extending wall cavities. The batt is adapted to be installed differently in closed cavities compared to open cavities. In certain example embodiments, stapling flanges or tabs are provided on a friction-fit batt so that (a) in closed cavity applications, the batt can be friction-fit installed in a closed cavity without the need for stapling, and (b) in open cavity applications, the same batt can be friction-fit installed and additionally stapled to the studs to significantly improve the batt's ability to withstand environmental conditions without falling out of the cavity.

Abstract: A system and method are provided for insulating a vertically extending wall (e.g., concrete wall). First and second supports are first attached to the vertical wall at respective first and second vertically spaced locations (e.g., proximate the top and bottom of the wall). After the supports have been attached to the wall, a blanket(s) of rolled fiberglass insulation (e.g., metal building insulation) is attached to the wall between the first and second supports. Then, a flexible sheet of vapor retarder is attached to protruding portions of the first and second supports so as to cover the blanket(s) of fiberglass insulation thereby causing the blanket of fiberglass insulation to be partially or fully hidden from view and retained in the cavity defined between the vertical wall and the vapor retarder.
