"Acorn was great. As a first time homeowner, I appreciated the recommendations they made for replacing the old insulation in our attic and getting the largest bang for our buck. At the same time, they didn't try to upsell us on things other contractors recommended. Overall, the price was competitive and the work quality was high."

Drywall Insulation questions, answered by experts

While adding insulation can be beneficial, there is too much of a good thing. Too much insulation can seal your house to the point where it can't release moisture that enters it—essentially trapping water vapor inside. Warm, humid climates are extra susceptible to mold from moisture issues, but homes in colder climates can experience condensation from an air-tight home when freezing temperatures thaw.

Yes, including recycled denim and cellulose from natural fibers.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’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.

Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.
