Dry your crawl space with an easy, economical ventilation option
What It Does:
Venting a crawl space with outside air brings summer humidity and cold winter air into your home, which leads to damaging mold and rot underneath your home.
The CrawlSeal™ Air System provides another way to ventilate a crawl space environment — with the already conditioned air present in your home. The CrawlSeal™ Air System is for use only in homes with central air conditioning.
The CrawlSeal™ Air System is intended as part of our crawl space vapor barrier system. When combined with our crawl space moisture barrier and vent covers, it provides a cost-effective way to keep a crawl space dry.
Mounting a CrawlSeal™ Air System in between the floor joists and installing a vent to the floor above will be done within the specified time frame for the rest of the job.
Properly Ventilating A Crawl Space
There are many products on the market these days that are used to ventilate crawl spaces. Some suggest taking air inside your crawl space and blowing it out of the house. Others recommend blowing air from the outside into your home. But what if it’s damp, humid, or cold outside?
At Ohio Basement Authority, we recommend installing a crawl space dehumidifier over using a crawl space fan. However, if you’re looking for a more economical way to dry your space, the CrawlSeal™ Air System is the way to go.
Since an encapsulated crawl space becomes part of your housing envelope, you can dry it without significant changes in your home’s energy efficiency. Depending on the size of your crawl space, this system will typically draw between 15 and 80 cubic feet of air per minute from the home above.
