What to Look For in Garage Insulation
To install insulation that performs well and lasts a long time, it’s important to choose the right type. The qualities below are some of the most important to have in the material that you invest in for your garage.
- Easy to Work With
- Doesn’t Retain Moisture
- Can be Installed in Space Available
- Not Too Heavy
- Decent R-Value
Best Material Types to Consider
Batts and Rolls
These materials are commonly used in garages because they are affordable and easy to install. The R-value of this material will vary between R-2.9 and R-3.8 per inch, so the exact value achieved in your garage will depend on the inches of insulation you have installed. While both batt and roll insulation are effective, it’s important to note that they will retain moisture. If you decide to have these installed in your garage, whether in the walls or on the ceiling, it’s important to also have a vapor barrier installed with it.
The R-value of this type of material will vary between R-2.9 and R-3.8 per inch, so the exact value achieved in your garage will depend on the inches of insulation you have installed. While the R-value can range from R-3.1 to R-3.8 depending on the material and thickness, it’s important to know that the material will settle over time. This can make it less effective, which is why it’s crucial to work with an experienced contractor who knows how much to install and where. If you choose this, they may recommend using it with other types of insulation to increase the effectiveness without costing you a lot more.
Although spray foam is one of the more expensive insulation choices for a garage, it performs beautifully and can last a long time. This is why it’s one of the most common choices for homeowners who are looking for the best value and performance for garage insulation. The R-value of this material can vary with the type, with open-cell spray foam having an R-3.7 rating per inch and closed-cell spray foam having an R-6.5 rating per inch. Either type of spray foam may be recommended by your contractor, depending on your garage and the space available.
Rigid insulation has an R-value of around R-5 per inch, making it a good choice if you’re looking for maximum efficiency. It can be used throughout your garage, including the main garage door, walls, and ceiling. When looking at choices, insulation that has a foil-backing is one of the best for the garage because it will prevent mold and mildew growth. The only downside to rigid insulation is the cost, although most homeowners feel it’s worth it for the results.
Reflective insulation is made with traditional pre-cut panels of insulation that are sandwiched between two layers of reflective polyethylene. It’s best installed on the garage door itself, as it will offer maximum performance in this area where it faces the sun. However, for the walls of your garage, you may want to go with a different insulation option that has a higher R-value.
Radiant barriers do not have an R-value because they do not absorb heat like traditional insulation does. Instead, radiant barriers reflect the heat of the sun to prevent the warm air from being absorbed into the garage. This is why it’s best to have it installed in addition to traditional insulation that will act as a second barrier for energy efficiency. A radiant barrier is best installed in areas of the garage that face the sun, such as the garage door and ceiling. Fortunately, this material is effective so it’s an easy choice to have installed.
Which Type is the Best for a Garage
Which Type is the Cheapest to Buy and Install for a Garage
Traditional fiberglass is generally the cheapest to buy and install in the garage. However, this may not work for your garage if your walls are exposed. Speak with a contractor to make sure a cheaper material will offer the value and longevity you’re after.
