Crawl spaces are a mostly overlooked feature of a home. Most homeowners will use them as storage, close the door, and not think much of it again until there’s an issue. However, a crawl space actually plays an essential role in keeping your home comfortable. Because of that, you want to ensure it’s properly insulated.
How do you know which type of insulation material suits your needs? Let’s take a look at some different types of insulation with some examples of where to use them to help you make the right decision.
Why Is Crawl Space Insulation Installation So Important?
Crawl space insulation installation can improve your home’s comfort and energy consumption. If you’ve ever noticed high energy bills you can’t explain or uneven heating and cooling in your home, a poorly insulated crawl space might be the culprit.
Taking control and insulating the crawl space can improve your home’s energy efficiency while reducing utility costs and improving indoor air quality all at the same time. Insulation creates a seal in your crawl space, preventing air from escaping. This is absolutely vital if you don’t want your HVAC system working in overdrive.
Covering the Types of Crawl Space Insulation Materials
There are multiple materials you can use to insulate your crawl space. But since each one offers something different, it’s important to know the advantages and disadvantages of each.
Fiberglass
When you think about insulation, you probably picture fiberglass. It’s one of the most widely used materials because it’s highly affordable and still works relatively well.
The batting consists of fine glass fibers that weave together to create a lightweight material. It’s also mostly easy to install, though all insulation installations are best done by a certified contractor.
Fiberglass falls short when it comes to fighting back against moisture. The batting can easily absorb moisture, making mold growth and water damage more of a potential problem. Those wanting to install fiberglass insulation will want to install a vapor barrier as well to avoid moisture issues in their crawl space.
Foam Board
Foam board (or rigid foam) is another popular choice. It’s usually made from polystyrene or polyurethane, both of which provide incredible thermal resistance. The boards also come in multiple thickness options. You can cut them to fit virtually any space, too, and they’re highly durable and last much longer than fiberglass in many instances.
The downside of foam board is that it’s generally more expensive. It’s also rigid, making installing more challenging if you aren’t hiring professionals. That’s only an issue if you go the DIY route; professionals are familiar with insulation installation in irregular spaces, so it should be no problem cutting and fitting them where you need to.
Spray Foam
Spray foam is one of the most versatile options because it’s the easiest in hard-to-install spots where you need something airtight. It’s also much more resistant to moisture and mold, making it a favorite choice for homeowners constantly battling a humid climate.
Spray foam is also more expensive, but the cost is often worth the trade-off for impressive, consistent insulation. It also has to be done by professionals, which is still recommended but worth mentioning for those wanting to know how the options stack against each other.
Reflective Insulation
Reflective insulation uses materials like aluminum foil to reduce heat transfer. While it’s not much of a strong insulator by itself, many homeowners install it to work with other types of insulation and further enhance thermal performance. In addition to being lightweight and easy to install, this insulation type reflects radiant heat.
But reflective insulation won’t be enough on its own. It’s also less effective in colder climates, which can make it an immediate pass in some situations, and it needs an air gap in order to work effectively.
How to Know Which Insulation Is Right for Your Crawl Space
Knowing about each type of insulation is only part of the equation. It’s also important to understand your unique situation in order to determine why you might choose one option over another.
Climate
The local climate is the most obvious consideration and likely the one that holds the most weight. People in colder areas will need better insulation to keep their homes warm, while those in warmer climates might prefer to add reflective insulation to reduce heat gain.
Moisture Levels
Some homes might be older or made of different materials, which could increase the chance of moisture becoming a problem. If you’re worried about moisture, you can opt for foam board or spray foam insulation installation rather than fiberglass batting.
Budget
Budget will be a major consideration for every homeowner. Those wanting a cost-effective choice will gravitate toward fiberglass. However, it’s vital to remember that you’re investing in long-term comfort. With that in mind, you should weigh your initial cost against the benefits over time and see what really makes the most sense.
Caring for Your Crawl Space: A Quick Insulation Maintenance Guide
Proper maintenance is crucial if you want your crawl space insulation to protect you for years to come. Here are some tips from professionals to help you do just that.
Have Your Crawl Space Inspected Frequently
Combine periodic inspections by professionals with frequent once-overs by you. These checks are crucial for detecting issues early on.
Monitor Your Energy Bills
Is the insulation working as intended? Notice any trends in your energy expenses and call a professional if you see a sudden spike; there may be an issue with your insulation.
Replace Damaged Insulation
If you see your insulation damaged or sagging, replace it immediately. Damaged insulation will not perform nearly as well and could cost you a lot of money if not promptly addressed.
