Benefits of Vapor Semi-Permeable Insulation on Masonry Walls in Hot-Humid Climates
An area’s average climate determines, in part, the types of materials used in residential and commercial construction. Hot and humid climates include parts of North and South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Texas, and Mexico according to Herbertson’s Thermal Regions (a modified version of the Koppen Classification scale).
Herbertson defines a hot and humid climate as a place that receives more than 20 inches of rain annually and exhibits one or both of these conditions:
In high precipitation areas, moisture can threaten the integrity of the structure and its materials. To keep standing pools of water, wind-driven rain and leaks from weakening the building over time, contractors need to incorporate construction technology that keeps moisture out and allows it to dry if it finds a way in. Among some of the most effective materials used are weather resistant barriers and vapor-transmitting insulation.
