Complexity |
|
This wall is moderately easy to construct. Trades can easily understand the methodology used to construct this assembly. Special care must be taken to ensure adequate fasteners for thicker levels of rigid insulation. The structural wood panel may act as a nailing base for the vinyl siding as well as brick tie attachment and may also be used as a substrate for stucco and/or foam plastic sheathing. A wood sheathing panel thickness of 7/16" is recommended to provide adequate racking resistance for the assembly. It may be possible to build this wall in a prefabrication process. |

Moisture Vulnerability |
|
This wall is moderately durable. The vinyl siding acts as a rain screen and is non-absorptive, helping to avoid solar-driven moisture issues. To improve drying to the inside, a variable permeance smart vapour retarder may be used as an alternative to polyethylene. Proper detailing around penetrations such as windows and doors is required to minimize any risk of moisture related issues. On-site construction moisture must also be appropriately managed. |
