Abstract: The present disclosure relates generally to methods, devices and systems for insulation, e.g., of cavities associated with walls, ceilings, floors and other building structures, with foam insulation. In one aspect, the disclosure provides a method for providing a cavity of a building with a predetermined amount of foam insulation. The method includes actuating a valve to begin dispensing foam insulation into the cavity, the actuation being performed by a user, the actuation by the user fixing a start time and/or a zero volume of a time and/or volume meter; then, dispensing the foam insulation from the insulation dispenser into the cavity as the time and/or volume meter counts time and/or volume dispensed; then when a predetermined time after the start time elapses or a predetermined volume of the foam insulation beyond the zero volume is dispensed as measured by the time and/or volume meter, actuating the valve to stop dispensing the foam insulation into the cavity.

Abstract: A method for filling a cavity with an expanding insulating foam component includes the following. First, providing a closed cavity comprising at least one elongated wall surface that extends along a first direction and includes first and second opposite sides, a top side and a bottom side. Next, forming a plurality of openings in the elongated wall surface arranged along the first direction and being alternating close to the first or the second opposite sides. Next, inserting a dispense tube through a first opening of the plurality of openings, and injecting a first portion of the expanding insulating foam into the closed cavity. The first opening is located close to the bottom side and close to the first side of the elongated wall surface. The injected foam expands along the bottom side and the first side and forms a first sloped top surface that has a positive slope angle.
