As the air moves through a duct, it interacts with the surfaces. The smoother that inner surface is, the better it is for air flow. The rougher the surface, the more it slows. of attic space ( ventilation ratio) measured at the attic floor level (ceiling). For large-volume attics, such as where roof slopes are greater thandesigners also should consider increasing the amount of attic ventilation to account for the additional volume of attic space.

R-value is the measure of a material's resistance to heat flow. The higher the R-value, the more resistant a material is to heat flow. If you lived in Minnesota, for example, you'd want R insulation in the walls instead of R, because R insulation is more resistant to heat flow, and.
