What is the Stack Effect?
Air enters from the bottom (crawlspace/basement), rises through living areas, and exits at the top. Unsealed crawlspaces allow humid, unconditioned air — often carrying mold spores, dust and allergens — to move into the home daily. Closing the crawlspace and controlling humidity interrupts this path.
Continuous vapor barrier + sealed vents keep soil moisture out.
Protect Structure
Prevents rot and decay in floor framing & insulation.
Efficient & Quiet
Aprilaire whole‑home dehumidifiers maintain RH below 60%.
Healthier Air
Encapsulation reduces spores, dust and other pollutants drawn up.
