Crawl Space Insulation
High humidity in a crawl space can cause moisture to condense on the crawl space insulation under the home. With enough weight, the insulation will droop and eventually fall, creating a problem in your crawl space.

Why do I need to insulate under my home?
What is R-value?
R-value is a measure of how well insulation resists heat flow. The higher the R-value, the better the insulation’s ability to resist heat flow.
R-value is measured in units of “per inch.” For example, an R-13 insulation batt has an R-value of 13 per inch. This means it will resist heat flow 13 times better than an inch of air.

What types of insulation does Dry Otter install?
Traditional Fiberglass Insulation in the subfloor:
- This type of insulation will last anywhere from 2-5 years to 15-20 years if it’s a vented crawlspace, depending on conditions.
- If this type is installed, it is secured between the floor joists and held up with thin metal rods. It should have an R-value of 19.
- It is important to note that if Fiberglass insulation is installed in a vented crawlspace, it can be problematic because it holds moisture. Still, with a proper encapsulation system, it should be fine.
Wall Foam Board Insulation:
- The walls can be installed with insulation in an encapsulated crawlspace. Dry Otter can install a rigid foam board on the interior crawlspace walls with an R-value of 10 to satisfy the insulation requirement.
- This provides an optimal solution with clear access to the subfloor if needed. This option is best because it is on the building envelope.
- It is important to note that if Fiberglass insulation is installed in a vented crawlspace, it can be problematic because it holds moisture. Still, with a proper encapsulation system, it should be fine.

Kiddos to the entire staff! ALNELLO2025-05-01Trustindex verifies that the original source of the review is Google. In today's business environment it's so rare to find a reputable company that stands behind their installations. Dry Otter is the real deal! I had a problem with a crawlspace dehumidifier they installed years ago. Dry Otter sent a tech out the same day, diagnosed the problem and ordered the new part . Three days later they came back and installed a new control board, covered under warranty. Their tech Daniel Soto even called the following day to make sure everything was working to my satisfaction. Mike Enloe2025-04-30Trustindex verifies that the original source of the review is Google. Very pleased with Curtis, Adam, Devon , and the install crew ( William, Josh , and Luis) of Dry Ottter ! Everything was on the up n up . Answered all questions clearly . Highly recommend this company and install crew for all water issues in unwanted areas of your basement.
