Do insulation companies need to be licensed?

• <div><p>In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s <a href="https://www.angi.com/angi-license-check.htm">license lookup tool</a> to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.</p></div>

Is bubble wrap or dish foam better?

• <div><p>Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. </p></div>

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 do I choose the right type of insulation?

• <div><p>Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you <a href="https://www.angi.com/articles/r-you-using-right-type-home-insulation.htm">choose the right insulation</a>. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.</p></div>
