Q: Is it OK to put plywood over insulation in an attic?

• <div><p>Installing sheets of plywood over <a href="https://www.angi.com/articles/attic-insulation-guide.htm">attic insulation</a> is a popular choice, especially in storage spaces.

In many houses, you&rsquo;ll need to install a subfloor before putting plywood over insulation in your attic.</p></div>

Q: Do cold walls mean poor insulation?

• <div><p>Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.</p></div>

Q: Can I install insulation behind drywall myself?

• <div><p>Yes, you can <a href="https://www.angi.com/articles/how-to-install-insulation.htm">install insulation</a> behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you&rsquo;re looking to add insulation, it&rsquo;s better to hire a professional, as you&rsquo;ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.</p></div>

Q: Can you install a radiant barrier under insulation?

• <div><p>It&rsquo;s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat. </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>
