Insulation is a great way to keep a house as energy efficient as possible. Homeowners preparing to insulate their crawl spaces should know a few things before they get started, though, especially if they plan to do it themselves. Even homeowners hiring a contractor would be better served by having some knowledge of the process ahead of time. The most important thing to know is which types of insulation are best for different climates. Since the effectiveness of insulation depends very much on the climate, the best crawl space insulation in Georgia will be very different from the best insulation in, say, Alaska. Those living in moderate climates can invest in relatively inexpensive fiberglass batts, which should be installed between floor joists (not tension rods, which compress fiberglass). It may need some new vents cut, as well as holes for electrical wiring. These holes can be sealed with spray foam insulation, and the ducts and plumbing should also be insulated for the most effective system. Cold climate denizens will, unfortunately, need to invest in more expensive, rigid insulation, unlike those looking to get the best crawl space insulation in Norcross, GA. To do the job right, the contractors should also remove all the vents and seal the holes. Then there’s more insulation that needs to happen, especially the rim joists on top of your foundation walls and the foundation of the walls themselves. Cold isn’t the only enemy, though. Moisture is also a problem in crawl spaces, which is why homeowners need to take precautions. Any kind of crawl space floor, finished or unfinished, will naturally have moisture leaking through, so it’s best to install a vapor barrier of polyethylene plastic to keep out the dampness. That won’t eliminate the problem entirely, though, since moisture can still come through the walls, so getting a sump pump and/or dehumidifier is a smart way to keep mold from growing in the crawl space.
