Crawl Space Insulation
"A properly sealed, moisture-protected, and insulated crawlspace will increase comfort,
save on energy costs, improve the durability of the home, and reduce entry of moisture, radon,
and other potential irritants or pollutants into the home."
"If you properly insulate your crawl space—in addition to air sealing and controlling moisture, you will save on energy costs and increase your home's comfort.

"How to insulate a crawl space depends on whether it's ventilated or unventilated. Traditionally, crawl spaces have been vented to prevent problems with moisture; most building codes require vents to aid in removing moisture from the crawl space. However, many building professionals now recognize that building an unventilated crawl space (or closing vents after the crawl space dries out following construction) is the best option in homes using proper moisture control and exterior drainage techniques. There are two main reasons for this line of thinking:

  • Ventilation in the winter makes it difficult to keep crawl spaces warm

  • Warm, moist outdoor air brought into the crawl space through foundation vents in the summer is often unable to dehumidify a crawl space. In fact, this moist outdoor air can lead to increased moisture levels in the crawl space."

Speak with a licensed professional to determine if insulating your crawl space is a good choice for your property. If so, he'll make sure it's done right and done to code.
