Water and moisture related construction defects are some of the leading causes of building failures, call-backs, and construction litigation in the US. One ASHRAE statistic states that 90% of construction defects ligation is due to water and moisture problems. ASTM estimates that water-related defects cost Americans over 9 billion per year in finish and structural damage. This course will look at the better and best ways to manage moisture through drainable wraps and rainscreens.
- Examine the importance of moisture management in wall assemblies, and discuss the consequences of not managing moisture effectively, such as mold, breakdown and damage to materials.
- Analyze the ways in which drainable wrap provides better moisture management.
- Identify the ways in which rainscreen systems provide the best moisture management solution, and explain the important part that rainscreens play in areas like drainage and water resistance.
- Evaluate installation best practices for drainable wrap and rainscreen systems, while identifying what the advantages are of a top vent, vent strip and corrugated rainscreen.
