Rethinking WRBs: Performance, Durability, and Efficiency in Modern Wall Assemblies
Exploring the role of self-adhered WRBs in achieving durable, energy-efficient building envelopes
Sponsored by TAMLYN | Andrew Hunt
Self-adhered weather-resistive barriers in modern wall assemblies, particularly within multifamily construction, offer a plethora of benefits to the builder, owner, and occupant.
This multimedia presentation will explore how self-adhered WRBs can contribute to improved air and water control, energy efficiency, and longterm durability. Though serving the same basic function as traditional mechanically fastened wraps, self-adhered WRBs can provide additional benefits by enhancing airflow and improving the tightness of the building envelope.
The presentation also addresses constructability considerations, detailing strategies and alignment with evolving building codes and performance expectations.

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.
