Is Crawlspace Insulation Needed Underneath Your Home? 

Crawlspace insulation needed –  Home Insulation is necessary in the regulation of temperatures in a home. Fiberglass is the most common type of insulation, but wool and cotton can also be normal materials in home insulation. Insulation can be found throughout a home to normalize temperatures inside. This helps keep the home cool during hot months, and warm during cold months. Insulation can be found in walls, ceilings and even in the attic to prevent hot air from escaping. In homes with a crawlspace, insulation in the subfloor can help regulate the temperature of the floor. Furthermore, keeping floorboards cool in the summer and warm in the winter.  

 Is Crawlspace Insulation Needed?

Insulation in the subfloor is beneficial. It helps to keep a barrier under the floorboards and prevent air from flowing out of the house through the crawlspace. This is crucial when a homeowner wants cool floors in the summer and warm floors in the winter. However, without proper maintenance, insulation in the crawlspace can quickly become a detriment to a home and cause headache. Insulation, when dry, holds the temperature in a home at a much more stable level. Air evaporating under a crawlspace can soak into that dry insulation and cause issues. Not only does it prevent the insulation from maintaining temperature, but it also soaks into the insulation. This helps to create a breeding ground for bacteria, mold, and fungus to grow. Not only does this make the insulation much less useful under the subfloor, but it also causes the insulation to gain weight and become displaced. 

 How Can It Effect Your Crawlspace?

When insulation is heavy, gravity slowly pulls it from between the floor joists where it is comfortably sitting, insulating the home from below. Even before it begins to sag, having that much moisture stuck up against the wooden foundation of your home can lead to wood rot. When the moisture level in the insulation becomes too much, the insulation can fall out of the ceiling, putting stress on essential services in the crawlspace . These service can include the homes HVAC, plumbing and electrical wires. If the problem comes from rotting or overly humid wood, the structure of the home can be compromised with warping. It is important to stay consistent when maintaining the crawlspace. These repairs will prove worthy when the temperature within the home stays consistent instead of escaping through the walls or floors.
