Best Crawl Space Insulation Materials

Insulation Materials for a Crawl Space

Rigid foam insulation offers high R-value, effective draft stopping, and excellent resistance to mold and moisture damage.

Crawl space insulation has a much bigger impact on a home's energy efficiency than most people realize. However, due to the difficulty of accessing the crawl space, insulation is often overlooked when people are aiming to improve energy efficiency and reduce heating and cooling problems.

Dr. Energy Saver offers proven solutions for crawl space insulation that are sure to make a difference in your home. Contact us today to discover how these products will work in your home!

Cold floors are a key sign of an under-insulated crawl space

If your house has a crawl space foundation, there are some very basic symptoms of poor crawl space insulation. During chilly winter months, floor areas above the crawl space will be cold and uncomfortable to walk on barefoot or in just socks. Another sign of improper crawl space insulation is musty odors coming up from below. Using the wrong kind of crawl space insulation can actually increase the likelihood that mold and mildew will grow in the dark, damp crawl space.

Foam, not fiberglass, is the right choice

The old-fashioned way of insulating a crawl space was to install fiberglass batt insulation between the exposed joists in the crawl space. Fiberglass is cheaper than other types of insulation and also widely available. However, its tendency to absorb moisture, support mold, harbor mice, and sag or fall out of place are all negative qualities that argue against its use in crawl spaces.

The best insulation material for crawl spaces is rigid foam insulation board. Instead of installing the foam insulation between floor joists in the crawl space, the foam board is installed against the crawl space foundation walls. Unlike fiberglass, rigid foam insulation does not absorb water, support mold or allow air to pass through (providing that joints between boards are sealed with tape).

Nick Nason completed an insulation evaluation and upgrade at our condo last winter. As a result of his excellent work our heating costs so far this winter are 50% of what they were last winter at this time, despite much colder conditions. In addition to the financial savings the level of comfort has improved tremendously.
