What are the four common types of insulation?

• <div><p>While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.</p></div>

Should you remove old insulation before adding new insulation?

• <div><p>You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.</p><p>However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.</p></div>

Q: How much difference does insulating a basement make?

• <div><p>Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.</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>

Q: Does tin foil on windows help with heat?

• <div><p>Spreading tin foil over your windows works similarly to <a href="https://www.angi.com/articles/radiant-barrier-cost.htm">radiant barrier insulation</a>, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn&rsquo;t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.</p></div>
