ATMOX controlled ventilation system is one of the best options for your crawl space. But there are a lot of other options out there: Vapor barrier, Temperature sensitive vents, Fans on humidistat or timer, Conditioned crawlspace with HVAC, House ventilator with exhaust fan, Closed crawlspace with dehumidifier, Solar powered attic ventilator (PAV), Powered attic ventilator (PAV) on a thermostat, Passive ventilation, and what we consider the best option, ATMOX controlled ventilation system.
Clean Space Encapsulation Systems uses a Vapor barrier / linear system to cover the whole crawl space. With the Clean Space Encapsulation system you still might need vents and other drainage options in addition to this.
With the ATMOX controlled ventilation system, you use the outside air only when it will improve the conditions in a crawlspace, basement or attic. It also enhances cross ventilation through use of fans, preventing condensation and additional moisture. ATMOX is probably the most energy efficient operation and easily adaptable to any size or difficult spaces. It is easily integrated dehumidifier for additional drying in basements and crawlspaces, as needed. The benefits for ATMOX really should out weigh any of the other options in cost and efficiency for your crawl space needs.
