System And Method For Minimally Invasive Injection Foam

A method for filling one or more wall cavities with an expanding insulating foam, the method comprising:

• determining a dispense rate for the expanding insulating foam, the determining comprising:
• providing a first test cavity comprising at least one elongated wall surface, wherein the elongated wall surface extends along a first direction and comprises first and second opposite sides;
• injecting a first portion of the expanding insulating foam into the first test cavity, the injecting being performed for a predetermined first dispense time or to dispense a predetermined first dispense volume of the expanding insulating foam;
• allowing the expanding insulating foam to fully expand to provide expanded insulating foam in the first test cavity;
• measuring a rise height of the expanded insulating foam in the cavity;
• then
• injecting a second portion of the expanding insulating foam into a second cavity to provide a predetermined rise height of expanded insulating foam in the second cavity, the injecting comprising:
• providing the second cavity comprising at least one elongated wall surface, wherein the elongated wall surface extends along a first direction and comprises first and second opposite sides;
• based on the dispense rate, determining a shot time or a shot volume suitable to provide the predetermined rise height of expanded insulating foam in the second cavity;
• and
• injecting the expanding insulating foam for the determined shot time or to provide the determined shot volume.
