Building enclosures are expected to manage and control moisture intrusion. Through a combination of building science, climate, and material feature discussions, this presentation will explore how to design water control layers for typical framed building enclosures properly. The focus will be on best practices for developing durable, resilient enclosures using moisture control systems that consider deflection, drainage, drying, and durability system components.

TAMLYN TAMLYN is a family-owned company with 50 years in the building products industry and has placed a great deal of recent focus on building science, especially moisture management. This direction led to the development of their TamlynWrap® line, Drainable with its 1.5mm bonded filament creating an enhanced WRB, and RainScreen 6.3 (1/4”) and 10.1 (3/8”). TamlynWrap® RainScreen is a multi-layer water management system, intended for use over existing WRB or coated sheathing, of cavity spaces that are non-compressible and act as a furring matrix to promote enhanced drainage and drying, paired with improved installation efficiency.
