Tighter buildings are more energy efficient but are also less forgiving when moisture gets into the assembly.
So, the question isn't just, “How do we keep water out?” It’s also, “What happens if water gets in? Where does it go? And how does the assembly dry?”
Our blog post looks at:
🔹 Why older buildings were more forgiving of moisture
🔹 How tighter assemblies change moisture management
🔹 Why drainage and ventilation matter
🔹 How rainscreen systems create pathways for water and airflow
🔹 Why building envelope components need to work together as a system
🔹 What should be considered during design
You can’t assume moisture will never get into an assembly. Good design plans for what happens when it does.
Read the full article to learn why better drying starts with better building envelope design.
