Crawl Space Insulation
When was the last time you thoroughly inspected your crawlspace? The quote “out of sight, out of mind” certainly rings true in this case. Like most people, you too might have forgotten about the crawlspace which exists beneath your feet. Not maintaining the crawlspace can have negative consequences for your whole house. A common problem people usually come across is stepping on a chilly floor on a winter morning despite the thermostat operating at full power. This is a clear indication that your home requires crawlspace insulation. The process involves using insulation material to maintain the temperature and quality of air inside the house.
Benefits Of Crawl Space Insualtion
The floor just above the crawlspace usually feels warmer or colder than the other parts of the house. This can be quite uncomfortable and is generally due to the air seeping in or out of the crawlspace. By insulating the crawlspace using the appropriate material, you can block off moisture and regulate the temperature inside the house.
Improved Air Quality
Both ventilated and unventilated crawlspaces allow moisture, dust, and dirt from entering the space making them a hospitable breeding ground for pests, rodents, mold, and mildew. When this happens, the quality of air inside the house degrades and can give rise to a plethora of health problems. Insulation prohibits moisture, pollutants, and other allergens from entering the crawlspace and thus improves the quality of air inside the house.
When moisture, dust, and dirt enter your house through the crawlspace, the HVAC system of your house has to work harder to compensate for the change in
temperature and air quality. Crawlspace insulation prevents this from happening and makes your HVAC units more efficient. This, in turn, will help you in making significant savings on your energy bill.

Closed-cell Spray Foam
Expanding foam is compressed in disposable cans or large containers and sprayed on the areas inside the crawlspaces that need to be insulated. It is expensive and unfortunately, it can leave behind odors, known as ‘Off-Gassing’. This musty smell can linger with the home indefinitely. Also, it’s nearly impossible to remove, which is absolutely necessary if structural repairs are ever needed. For these reasons, we do NOT recommend closed-cell spray foam in crawl spaces.
Rigid Foam Insulation is installed on crawlspace walls by carefully shaping the 4’x’8′ sheets of foam board and gluing them to the walls. These insulation panels are made up of a close-cell insulation design. Rigid foam costs comparatively lesser than spray foam and possesses an R-value equivalent to its spray counterpart. It is waterproof and creates a vapor barrier to prevent moisture from entering crawlspaces. It also traps heat lost from the ductwork in the crawl space, leading to energy savings.
