Abstract

Claims (28)

1. A building component manufacturing method comprising:

providing a structural component of a building, the structural component comprising:

a frame comprising a plurality of outer components coupled together to define an outer periphery of one or more sections, wherein at least one of the sections comprises a cavity;

applying a pour-in-place insulation material within the cavity to insulate the structural component, wherein the pour-in-place insulation material transitions from a liquid state to a solid state to form a first layer of insulation within the cavity;

monitoring, using one or more sensors, a fill level of the pour-in-place insulation material within the cavity relative to a desired fill level while applying the pour-in-place insulation material; and

controlling a flow rate of the pour-in-place insulation material based on the fill level within the cavity as determined by the one or more sensors, wherein controlling the flow rate comprises adjusting the flow rate of the pour-in-place insulation material at one or more locations to achieve the desired fill level based on the fill level within the cavity as determined by the one or more sensors and an expansion rate of the pour-in-place insulation material.

2. The building component manufacturing method of claim 1 , wherein:

the structural component further comprises a generally planar surface, the frame being positioned atop one side of the generally planar surface so that a lateral boundary of the cavity is defined by the at least one of the sections and a base of the cavity is defined by the generally planar surface.

3. The building component manufacturing method of claim 1 , wherein applying the pour-in-place insulation material comprises:

positioning one or more nozzles over the cavity; and

injecting the pour-in-place insulation material within the cavity through the one or more nozzles.

4. The building component manufacturing method of claim 1 , wherein:

the pour-in-place insulation material is characterized by a viscosity of between about 250 centipoise and about 800 centipoise, wherein the viscosity is measured at a temperature of about 75 degrees Fahrenheit.

5. The building component manufacturing method of claim 1 , wherein:

the first layer of insulation is characterized by a density between about 0.3 pounds per square foot and about 10.0 pounds per cubic foot.

6. The building component manufacturing method of claim 1 , wherein:

the first layer of insulation is characterized by an insulation R value of greater than or about R−3 per inch of the first layer of insulation.

7. The building component manufacturing method of claim 1 , wherein:

monitoring the fill level within the cavity comprises detecting, using the one or more sensors, the fill level of the pour-in-place insulation material, a fill level of the first layer of insulation, or both within the cavity.

8. The building component manufacturing method of claim 1 , further comprising:

monitoring the fill level within the cavity comprises detecting that the fill level of the pour-in-place insulation material at the one or more locations of the cavity are below or above a desired fill level.

9. The building component manufacturing method of claim 1 , further comprising:

subsequent to the pour-in-place insulation material transitioning to the solid state and forming the first layer of insulation, detecting at least one location of the cavity that has an incomplete fill level; and

applying an additional volume of the pour-in-place insulation material within the cavity to further fill the cavity.

10. The building component manufacturing method of claim 1 , wherein:

the first layer of insulation is applied at a site where the building component is manufactured, wherein the site where the building component is manufactured is remote from a site where the building component is to be installed.

11. The building component manufacturing method of claim 1 , wherein:

the expansion rate of the pour-in-place insulation material comprises one or both of a current expansion rate and an empirical expansion rate.
