Even though it’s not always visible to us, insulation plays a significant role in improving the comfort and energy efficiency within residential environments.
On top of insulating areas above ground like the external walls, the attic, and the roof, you also have to consider the areas beneath your home. Insulating the crawl space, for example, is an important aspect of achieving proper insulation for the entire house.
Below, we share the top seven reasons why you should insulate your crawl space.
1. Energy Efficiency
Out of the many benefits of insulating a crawl space, reduced energy consumption stands out as the most popular reason why homeowners install insulation under their homes. Without insulation, the heat or chill from the outside can easily penetrate into your home’s living spaces, requiring your HVAC system to work more to keep the indoor temperature at your desired level.
Next to the attic, the crawl space is the most important part of your house to insulate since it tends to be infiltrated by drafts that can cause a significant loss of heated or cooled air inside your home. So, if you’re searching for an opportunity to save energy in your home, prioritize insulating your crawl space.
2. Better Air Quality
Many outdoor pollutants, such as dust, pollen, and vehicle fumes, enter your home through unsealed gaps and cracks on the building envelope.Air sealing, when done together with insulation, not only keeps your living spaces comfortable, but it also prevents your indoor air from being contaminated by impurities from the outdoors.
A well-insulated home offers better indoor air quality and prevents the ingress of particles and pollutants that can pose a health hazard to its occupants. Your crawl space can be especially prone to mold growth. With insulation, you reduce the formation of moisture and condensation under your home, thus also reducing the chances for mold to grow while keeping your indoor air nice and clean.
3. Sound Control
Insulating your crawl space with fibrous materials such as cellulose, fiberglass, and mineral wool can reduce both airborne and impact noises from entering or traveling around your home. Whether you don’t want to hear your loud neighbors or you want to block out any construction or traffic noises nearby, installing insulation is a guaranteed way to reduce permeating sound waves that can disrupt the peace and quiet within your household.
4. Pest Prevention
Attics, basements, and crawl spaces are common areas for pests to invade. If you’re not paying attention to the state of your crawl space, who knows what could be crawling in there and threatening the health of your family by carrying various diseases and leaving their excrement behind?
Many rodents and insects prefer narrow and humid spaces, especially one with lots of cracks for them to crawl into. This makes your crawl space a prime candidate for infestation. Insulation that’s properly and neatly installed, however, can help keep your home pest-free while reducing drafts and cold spots.
5. Improved Comfort
Temperature regulation serves the dual purpose of reducing your energy consumption and keeping your rooms cozy throughout the summer and winter months. The living spaces above your insulated crawl space can be the perfect place for your family to spend time together or for the guests to be entertained.
6. Longer-Lasting HVAC Systems
If you want to keep your HVAC system functioning for as long as possible, you definitely need to consider crawl space insulation. When an HVAC system needs to work harder to heat, cool, or ventilate a home with inadequate insulation, it can encounter problems much sooner than systems in well-insulated homes.
Heat transfer may not seem like much of a threat, but it’s definitely making your HVAC system put in more work to keep your house as cold or as warm as you want it. Have in mind that these systems are costly to install and replace, especially if it includes ductwork. Fortunately, there are a few simple ways for you to ensure that it’s kept in good condition, such as periodic inspections, regular maintenance and repair, , and of course, proper insulation around your home.
7. Helps Reduce Fire Spread and Damage
Mineral wool and fiberglass insulation are both naturally fire-resistant materials that slow down the spread of flames. They can even play a crucial part in stopping a fire from developing in the first place.
Mineral wool is especially ideal for thermal applications due to its fire-resistant qualities. Because non-organic components are used, such as recycled iron and steel byproducts, the material is non-combustible and has a very high melting temperature.
Other types of insulation that aren’t completely fireproof, such as cellulose, can still be treated with flame retardants that can help it withstand high temperatures. When installed in crawl spaces, attics, and external walls, you can have better peace of mind knowing your home is less prone to fires.
If you’re looking to make your home more energy-efficient, safer, and more comfortable, crawl space insulation offers all that and more. And the best part is that once it’s installed, you reap all the benefits without additional work, making it a solid investment for any homeowner.
