ECOPLY BARRIER ADVANTAGES. 4 . 1 A RC H I T E C T S / D E S I G N E R S. Modern construction practices are moving toward providing greater energy efficiency and an airtight building envelope. These principles of high performance building are common in nearly all current green building standards and construction codes. Proper sealing between wall assembly components prevents unwanted air movement in and out of conditioned air spaces. Advantages: Ecoply BARRIER can form an integral part of a weathertight system including two of the four Ds' of weathertightness.

9 Drying and drainage. A rigid air BARRIER provides a more robust cavity and prevents the insulation bulging, which would increase the chance of moisture bridging from the cladding to the framing line. Provides both structural support and protection from moisture. Structural bracing is achieved when installed in accordance with the Ecoply BARRIER bracing specifications. Bracing benefits may result in cost savings by reducing internal lining bracing elements (Refer to section on bracing).
