What is the difference between R19 and R13 insulation?

There is a direct relationship between the amount of insulation and the amount of heat transfer. The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.

Can you put rigid foam insulation between studs?

Even with its flaws—namely, its inability to perfectly mold to the bays between the studs—rigid foam insulation will be a better bet than no insulation. Using low-expanding spray foam sealant to seal those gaps further increases rigid foam’s insulating properties between studs.

What's the highest R-value insulation for a 2x4 wall?
