Q: What's the difference between fiberglass insulation and foam board?

• <div><p>When it comes to <a href="https://www.angi.com/articles/fiberglass-insulation-vs-foam-board.htm">fiberglass insulation versus foam board</a>, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass. </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>

Q: What is the best insulation for air ducts in the crawl space?

• <div><p>Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.</p></div>

Q: How long does fiberglass insulation last?

• <div><p>The <a href="https://www.angi.com/articles/when-should-i-replace-my-insulation.htm">life span of fiberglass insulation</a> can be as long as 80 to 100 years, but because of changing building codes, it&rsquo;s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.</p></div>

Went good. Guys that came were knowledgeable and nice. Installed to me what looked to be as they showed me. The only thing was the outside drain ended up below the level of the ground and they kind of made a well but using bricks that I had in the area. Not so pretty to look at.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
