Can I use fiberglass insulation to soundproof a room?

• <div><p>We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. <a href="https://www.angi.com/articles/diy-dangers-fiberglass-insulation-hazards.htm">Fiberglass insulation is dangerous</a>, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.</p></div>

Can I add new insulation without removing the old insulation?

• <div><p>As long as your existing insulation isn’t compromised, you can add new insulation directly over them. <a href="https://www.angi.com/articles/how-to-inspect-and-repair-your-insulation.htm">Inspect your insulation</a> thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.</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>

Q: Should plaster walls be insulated?

• <div><p>Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.</p></div>

Q: What do soffit vents do in winter?

• <div><p>One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect&mdash;mostly just closing the vent in the fall. What&rsquo;s most important is your attic is ventilated to some degree in the winter.</p></div>
