摘要： 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. Next, inserting the dispense tube through a second opening of the plurality of openings located close and above the first opening and close to the opposite second side, and injecting a second portion of the expanding insulating foam into the closed cavity. The injected foam expands along the first sloped top surface and the second side and forms a second sloped top surface that has a negative slope angle.
