Get matched with top insulation pros in Alexandria, TN

Q: Which floor is warmest in winter?

• <div><p>Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.</p></div>

Q: Does a higher R-value mean the insulation is better?

• <div><p>Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.</p></div>

Q: Should I remove old cellulose insulation before installing new insulation?

• <div><p>Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there&rsquo;s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you&rsquo;re unsure how to assess the presence of mold or mildew, talk to a <a href="https://www.angi.com/companylist/mold-testing-and-remediation.htm">mold remediation specialist near you</a>.</p></div>

Q: What is the purpose of insulation?

• <div><p>The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that&rsquo;s cool air when it&rsquo;s hot out, or warm air in winter, but that&rsquo;s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.</p></div>

Q: Does an insulated garage need roof vents?

• <div><p>An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.</p></div>
