The total R value you need depends on two issues.
- Where you live;
- How you use your garage.
An R-value in the 6 to 9 range is fine for most garages in our area. But if you have living space directly above, or connected to the garage, or if it is used as a heated workshop, a garage door with an R-values up to 19.4 might be in order.
