What are the best ways to insulate an attic?

• <div><p>Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into <a href="https://www.angi.com/articles/diy-spray-foam-insulation-kits.htm">spray foam insulation</a> or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.</p></div>

How much does it cost to rent an insulation vacuum?

• <div><p>The cost to rent an insulation vacuum ranges between <b>$250 and $350 per day</b>. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost <b>up to $1,000</b>. Once you've removed the insulation and are ready to replace it, the <a href="https://www.angi.com/articles/cost-to-rent-blown-insulation-machine.htm">cost to rent a blown-in insulation machine</a> ranges between <b>$100 and $500</b>.</p></div>

Q: What does the R-value refer to when it comes to pipe insulation?

• <div><p>The R-value is a rating that measures the insulation&rsquo;s thermal resistance (in other words, how well it insulates). For most pipe insulation, the R-value will fall between one and five. The higher the R-value, the more protection for your pipes. All pipe insulation materials should have an R-value listed in the product description or on the product label. </p></div>

Q: Is it worth insulating an unheated garage?

• <div><p>Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.</p><p>If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.</p></div>

Q: What is the most affordable way to insulate behind drywall?

• <div><p>The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around <b>$0.75 per linear foot</b>, with the width matching the gaps between standard studs perfectly. However, it&rsquo;s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn&rsquo;t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.</p></div>
