"The team at Dana Insulation is top notch. From Tom in sales to the installation team everyone was courteous and professional. They put down protective plastic on the floors so as not to get any dirt or insulation on the floors. Did a great job cleaning up after the job as well. Thank you very much Dana Insulation!!!! I would definitely recommend this company!!!"

Insulation questions, answered by experts

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

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.

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.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.
