Insulation questions, answered by experts

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.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

Yes! Outdoor faucet covers work by enclosing the faucet with a thick, insulating material that will keep the faucet warmer than outdoor temperatures. They need to be sealed tightly against the house to work properly, though, so be sure to tighten the rubber strap or drawstring on the insulation cover to best protect your faucets.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.
