Q: What is the lifespan of crawl space insulation?

• <div><p>The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. </p></div>

Q: Does the type of garage door affect the insulation?

• <div><p>The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. </p></div>

Q: What is R-value and what is the R-value of injection foam?

• <div><p><a href="https://www.angi.com/articles/what-r-value.htm">R-value</a> stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.</p></div>

Q: Is it OK to put plywood over insulation in an attic?

• <div><p>Installing sheets of plywood over <a href="https://www.angi.com/articles/attic-insulation-guide.htm">attic insulation</a> is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air&mdash;so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. </p><p>It&rsquo;s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you&rsquo;ll need to install a subfloor before putting plywood over insulation in your attic.</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>
