Why straightedge inspections are critical after spray foam and before drywall! 🏗️📐
At Sprucehill, quality control requires verifying that mechanical rough-ins remain planar after insulation is installed. On this site walk-through, we are highlighting how expanding spray foam can distort drywall surfaces.
Boarding walls without verifying stud planes carries expensive cosmetic and finish stakes.
As spray foam expands within stud bays, it can push flexible ducting, plumbing lines, or rough-in boxes proud of the framing plane. If left unaddressed, boarding over these obstructions creates prominent humps across finished drywall that interfere with millwork and baseboard installations. By inspecting every wall with a straightedge, we can relieve pressure behind displaced lines or fur out the framing by a 1/4-inch or 1/2-inch to ensure a perfectly flat finish.
