Insulation questions, answered by experts

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

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.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

Adding too much insulation can have detrimental effects on your home and on your wallet. Where you live will determine the optimal amount of insulation for your home and in your ceilings. Adding more than the recommended amounts can cause airflow problems that can lead to moisture trouble. You may also spend more than necessary by adding too much insulation to the point that it'll become unrecoverable through your energy bills.
