Q: Is it worth it to remove old attic insulation?

• <div><p>The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.</p></div>

Q: Should you insulate your entire attic?

• <div><p>Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you&rsquo;ll need to do down the line. </p></div>

Q: What materials are most effective for soundproofing?

• <div><p>Acoustic foam, fiberglass insulation, soundproof curtains, and specialized drywall are effective in reducing noise transmission.</p></div>

Q: Why should attic insulation installation be done professionally?

• <div><p>Ensures uniform application and maximizes insulation effectiveness and energy savings.</p></div>
