In a hot-humid climate, moisture flows from outside to inside most of the year. In a mixed-humid climate, moisture flow changes direction in cooling and heating seasons. Using the proper wall assembly in your home is important for controlling moisture.
R-value is standardized measure of a material’s resistance to heat flow — the higher the R-value, the greater the insulating ability. However, the actual R-value of a wall or ceiling can be a lot less than the R-value of the insulation material in it, depending on the installation.
To overcome the forces that wind places on a building, construction of the walls with connectors and sheathing is important.
