The Stack Effect

Tuesday, June 17th, 2014 by Heather Burton


Most of you probably have the thought: "I don't go in my crawlspace what do I care what it looks like?"

Well, the answer to that question is you should care an awful lot because of the phenomenon found in your house commonly referred to as the Stack Effect. If you have an attic or more than one story on your home you are probably aware that it is always warmer on the higher levels. The same goes if you have a basement: it is always cooler down there. Why, though? Well, air is pulled in from outside your home starting at the bottom and is then rises to the top. The colder air is "heavier" and the hotter air is "lighter", cold air sinks and hot air rises, we all know that. Pressure from the outside pushes the air into the bottom of the house and while the hot air rises, that negative pressure on the inside pulls the air out of the top.

Now think about how nasty your crawlspace probably is, all the air floating around in there is seeping up into your house. If it's damp down there, so is the air. Damp air carries mold spores, dust mites, and also causes wood in your house to warp. This means you are breathing in all of that and it is also attaching to your furniture, walls, floors, and ceilings as it passes through your house. If you have doors or windows that seem to stick or there is swelling when once they were fine this can be part of the reason. The damp air is also harder to cool and heat versus dry air circulating through your house. Don't worry though, there are solutions!

A great solution is to have your crawl space encapsulated with a premium vapor barrier, the CleanSpace Vapor Barrier, and to install the SaniDry CX dehumidifier. If you have standing water issues you should also look into getting a TripleSafe sump pump with a perimeter drainage system and drainage matting underneath your CleanSpace liner. And if you still want insulation that won't get moldy or damp ask about SilverGlo. You also need to make sure your vents and entryway are properly sealed, so moist humid air doesn't continue to seep into the crawlspace or basement.
