Exterior System Components
A critical design consideration for exterior wall applications is the use of a vapor retarder to control moisture migration through the wall . This is done to minimize the potential for condensation within the cavity.
HYDRODRY® is a proprietary self-draining, ventilated wall moisture control system that works by creating a defined drainage and ventilation cavity behind veneer stone, stucco, fiber cement and various other exterior claddings. HYDRODRY® allows your exterior walls to drain and breathe to help protect the structure and air quality of your home - A dry home is a healthy home.
Moisture Movement and Condensation Control in Exterior Wall Assemblies
Understanding and predicting moisture movement within and through exterior wall systems is one of the most important factors affecting enclosure performance. Condensation issues can occur with or without designed air barri-ers, and it is important to understand the role ventilation plays in the design.
Rainscreens 101
One of the key differentiating factors for rainscreen systems is where the system is positioned relative to the insulation and cladding. This decision impacts the wall's thermal performance, moisture management, and ease of installation. Exterior Framing Applications In this method, the rainscreen is part of the external framing layer.
Wall assemblies should be designed and built to reduce and control condensation during cold weather. Condensation control includes reducing and limiting the potential for condensation, safely storing any condensation that does occur, and quickly drying out moisture when drying conditions return.
Ideal Wall Assemblies for Hot
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 .
