// LESSONS FROM Greenfiber
Hard early mentors you didn't like at the time often deliver the most lasting career value—recognize and repay that by becoming one yourself.
Cellulose is the pragmatic retrofit insulation choice because its hygroscopic properties tolerate the moisture unknowns that make spray foam or fiberglass risky in older Maritime housing stock.
Dense-pack cellulose wall installation success comes down to tracking bag count per section—3.5 lbs/cubic foot is the target density that prevents settling without on-site equipment.
The two-inch post-install drop in attic cellulose depth is designed in, not a defect—educating crews on this prevents unnecessary job-site disputes.
Spray foam has significant on-site failure modes (substrate temperature, product age, machine calibration) that cellulose, as a plant-manufactured product, inherently avoids.
For new products requiring code compliance, the entry path must hit architects, building codes, and contractors simultaneously—each alone is insufficient.
