Insulation questions, answered by experts

Choose affordable materials for a cost-effective insulation installation (say that five times fast). The most affordable insulation for your garage is fiberglass. Fiberglass comes in batts or rolls and is relatively easy to install compared to other types of insulation. You can also install this insulation without needing to drywall over it, which can cut down costs.

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.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

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.
