What does R-value mean in insulation
The R-value of a material indicates its insulation effectiveness. The higher the R-value of a material, the better it enhances energy efficiency in your home.
Materials with a high R-value have a higher resistance to heat transfer. If you live in a cold region, you need insulation materials that prevent heat loss. The higher the R-value, the warmer they will keep your home. Hence, the better insulation they provide.
Spray foam has the highest R-value compared to other often used insulation materials.

Factors to consider before adding insulation and drywall to your garage
Depending on where you live, the building codes will specify the type of drywall needed to finish a garage.
Building codes focus on safety. Therefore, they will recommend that you use a drywall that is fire resistant.
Building inspectors in your region will have to approve the drywall installation before you can use the garage. If you do not follow the building codes, you will have to repeat the job or keep the garage unused.
The weather in your location determines how you will finish your garage. In high-temperature regions, you will have to insulate the doors and walls to keep the garage cool.
In low-temperature areas, insulate the walls and ceiling to keep the garage warm and usable.
The weather also determines the type of drywall you will use. In humid locations, avoid drywall that cannot resist moisture.
Hire a pro or DIY
Determine earlier whether you will hire a pro or DIY. Most people will destroy many sheets of drywall before they can hang it correctly. To avoid this and save money and time, hire a pro.
Before you hire, make sure you know how much you will pay for the project. Collect at least three quotes from professionals to compare and hire one within your budget.
However, if you have the tools, skills, and time to finish the task by yourself, you can save money by hanging the drywall yourself.
How you will use the finished garage
How you will use the garage once it is finished will determine the type of drywall and insulation materials to use.
