What Makes Rainscreen Walls Work?
September 30, 2021 @ 1:00 PM - 2:00 PM EDT
Live webinar sponsored by the Air Barrier Association of America
Curious or confused about what “rainscreen” means or how it relates to wall performance? In this seminar, Graham Finch of RDH Building Science will provide an overview of rainscreen wall designs, including all the visible and hidden components and important factors in performance. Claddings and attachments, the air cavity and why width matters, water control, structural considerations, fire and combustibility, exterior insulation … all this and more will be touched on.
This seminar will be of interest to a wide audience within the building industry, in particular architects, designers, contractors, and material suppliers who are interested in the design and construction of rainscreen walls across North America.
- Describe the components of a rainscreen wall and their functions.
- Integrate the science and practical aspects of rainscreen wall performance.
- Discuss specific considerations for heat, air, and moisture control as well as structure and fire.
- Design and detail higher performance rainscreen walls.
Graham Finch, Dipl.T, MASc, P.Eng
Graham is a Building Science Engineer with RDH Building Science in Victoria, BC who specializes in enclosure design, research, and investigation work for new and existing buildings. His work experience includes a wide range of projects including building enclosure and facade design and analysis, forensic investigations, research studies, building monitoring, enclosure testing, and various product development and testing services for projects across Canada and the US.
Graham is regarded as an industry leader in evaluating thermal energy and hygrothermal (heat, air, and moisture) performance of building enclosures. Specific to rainscreen walls, much of his practice and graduate research has focused on hygrothermal performance of rainscreen wall assemblies. His research has resulted in several publications and practical recommendations for the construction industry for rainscreen wall designs. Graham is also the co-chair of the Rainscreen Performance Committee for RAiNA.
