A Hidden Source of Discomfort and Energy Waste
Crawlspaces are often neglected in home construction and upgrades, yet they have a huge impact on comfort and efficiency. Older homes may have no insulation at all, while newer ones often rely on fiberglass batts that sag, fall, and lose effectiveness over time. Vented crawlspaces also allow outside air to infiltrate, making floors colder and energy bills higher.
Proper crawlspace insulation goes beyond simply adding fiberglass. At Atlas, we seal air leaks, install vapor barriers, and use closed-cell spray foam to keep your home protected from humidity, drafts, and even radon gas. The result? A safer, drier, and more comfortable living environment year-round.
