Crawlspace insulation is a great way to increase the energy efficiency of your home. You’ll be able to lower your utility bill and protect the HVAC system from the elements. However, it’s important to choose the right type of insulation for your needs.
How do I protect my crawl space from moisture?
One of the most common types of insulation is fiberglass. It’s also the easiest for a do-it-yourselfer to install. Fiberglass batts are often used in between floor joists. They should be a snug fit and have a paper vapor barrier facing up.
Another option is closed cell foam insulation. This is a good choice for rim joists, as it has an R-value of about 98%. It’s also easy to install and is fairly light.
If you’re not into the DIY way, spray foam can be a more cost effective way to protect your crawl space. The benefits of this type of insulation include its ability to prevent moisture from getting into the walls. It’s also a surprisingly effective method of stopping air leaks.
Other forms of insulation for your crawl space might be a better choice. While spray foam is considered the best of the lot, rigid foam is also a viable solution.
When it comes to choosing the right kind of crawl space insulation for your needs, it’s important to remember to keep in mind your unique circumstances. Your choice can help you maximize the benefits and avoid the potential drawbacks.
For example, if you have a cold floor, you may need more than just insulation. Installing a vapor retarder on the ground beneath the insulation will prevent moisture from forming.
