Q: Is it worth it to insulate a garage?

• <div><p>Insulating a detached garage won't reduce your home's heating or cooling bills&mdash;and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.</p></div>

Q: Is installing crawl space insulation worth it?

• <div><p>Yes, <a href="https://www.angi.com/articles/why-should-i-insulate-my-crawl-space.htm">crawl space insulation is worth it</a> if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home.

Q: What is the best insulation for soundproofing a room?

• <div><p>Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.</p></div>

Q: What is the life expectancy of wool insulation?

• <div><p>Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years. </p></div>
