Bassett Construction provided design assist and installation services for a custom rain screen roof system for Portland Japanese Garden’s Cultural Crossing expansion project.

A unique requirement of the rain screen roof system is that it needs to be walkable. Additionally, there are extreme wind load requirements on this project do to its hillside location. To meet these requirements, a custom engineered supporting fin system was utilized on the underside of the panels. The roof system buildup is complex, but can be described as support angles and clips fastened and sealed to the roof system to create a raised level grid. Then custom extrusions attached directly to the back of the material with supports running across the field of the panels to create a walkable roof.
