What is the highest R value for 2×4 walls? They are available in widths suited to standard spacings of wall studs and attic or floor joists: 2×4 walls can hold R-13 or R-15 batts; 2×6 walls can have R-19 or R-21 products.
Can you use R19 instead of R13? 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.
Where is R19 insulation used? In many regions of the country, R-19 insulation is recommended for use in outer walls of new construction projects. A different type of insulation is used in areas like basements and attics, and to insulate floors.
