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.
