What are the four common types of insulation?

• <div><p>While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.</p></div>

Q: How do I know if my crawl space needs insulation?

• <div><p>Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they&rsquo;re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.</p></div>

Q: What insulation generally has the highest R-value?

• <div><p>Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they&rsquo;re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It&rsquo;s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.</p></div>

Q: Does wool insulation need a vapor barrier?

• <div><p>The primary reason that <a href="https://www.angi.com/articles/insulation-saves-you-money.htm">insulation saves you money</a> over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code. </p></div>

Q: Will pros manage window drafts more effectively than DIY methods?

• <div><p>Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.</p></div>
