Response to Erica Downs by Martin Holladay Erica, Q. “Can you please clarify why you need air flow between the living space and crawl space?” A. As stated in the article, the requirement for a floor grille to provide air flow between the living space above and the crawl space below is a code requirement found in the 2006 IRC, section R408.3. If you choose Option 1, and install an exhaust fan in the crawl space, the grille is the source of conditioned makeup air from the crawl space. If you choose Option 2, and install a supply register in the crawl space, the grille allows the air in the slightly pressurized crawl space to flow to the house above, at a slow rate, thereby mixing the crawl space air with the home’s conditioned air. Some builders have had good success with sealed crawl spaces that lack an exhaust fan, a supply register, or a grille connecting the crawl with the living space above. Omitting conditioning sometimes works and sometimes doesn’t. In all cases, however, it would be a violation of the 2006 IRC.

Response to Ted Clifton by Martin Holladay Ted, Concerning your two suggestions: 1. I don’t doubt that your proposed insulation method — insulating the floor above the crawl space as well as the crawl space walls — results in a dry crawl space and good thermal performance. Many builders and homeowners will balk at the added expense of insulating twice to create a double thermal envelope, but for those who are willing to go that route, I’m sure your proposed insulation method will work. To me, the complicated solution just highlights the inherent disadvantages of crawl spaces. 2. In my article, I explained the two options listed in the International Residential Code for conditioning crawl spaces. One option is to install a fan that exhausts air from the crawl space along with a grille that provides makeup air from the house. Although you don’t like that method, it is one of two code-mandated options, and it works in most climates. The question of how to condition a sealed crawl space is enormously contentious; suffice it to say that no method of crawl space conditioning is without drawbacks, and there are strong arguments on all sides of this issue. If you have a system that works well for you in your climate, and if your local building inspector approves of your method, then go for it. There are some risks to your approach — the possibilities of poor indoor air quality or high radon being among them. But if you have satisfied yourself that your homes don’t have these problems, you are good to go. Again, these contentious issues remind me of why slabs on grade look good.

28. May 18, 2011 10:22 PM ET Unvented crawl space over sold by Glen M First let me say, if constructed as outlined here, an unvented crawl space works, however, I believe they are over sold. Do they work, yes, do they require very specific attention to detail that is common to the construction trades today, not even close. My parents live in update NY with part of the house with a full basement and another on a vented crawl space, which has slab below with uninsulated cmu walls. The crawl space is insulated with 10-12″ of fiberglass batts on the underside of the floor and has two vents. This crawl space was built in the early 70s and never, I repeat, never have there been any moisture problems. Yes, the slab likely retards the moisture flow from the ground to the space, but this house was not built to any Fine Homebuilding standard. I now live in Houston (i.e. hot and humid) on a raised floor house on “drilled” piers, which as noted here has other some advantages and is commong practice in “expansive” soils. This is obvisouly not common practice in the Northeast. I have 4″ of spray foam on the underside, no slab below, with perimeter lattice all the way around the house so there is plenty of air movement. Periodically I inspect the crawl space particularly during the summer and have no issues, in fact, it is actually pleasant (as much as that is possible) during the hot/humid summers. Obviously different regions require different solutions, but I believe the amount effort to truely seal a crawl space and maintain it (I have to run an exhaust fan, come on) in most situations (except for extremely cold climate, ducts in the space) is over sold. For my money, build the perimeter however you want (cmu, cast-in-place, etc), provide adequate venting (i.e. exceed code) and use closed-cell spray foam on the underside, call it a day. As far as termites are concerned, remember they need a food source + water, remove one and no termites. What typically is installed down here is a terminte shield which is essentially a sheet metal cap which contrary to most people’s understanding, is not a barrier but an obstacle that they have to build around. Since they have to build around it, their “tunnels” would be visible from a periodic inspection of the foundation.
