Open Joint Siding System

This paper discusses the implications of open joints for the performance of rainscreen systems.

Open joint siding system.

Recent trends in the design of exterior claddings have seen an increase use of open jointed rainscreen cladding systems. The downside of the open joint design is that areas of the water resistive barrier are left exposed to sunlight. If your project calls for a panelized look the reveal panel system offers the design flexibility you need.

In these systems the joints between the cladding elements are intentionally left open. Click the register link above to proceed. Various approaches to the design of open jointed rainscreen cladding systems will be are discussed and some case studies demonstrating the detailing of open jointed cladding systems are presented. In the seattle area where i work we get a lot of rain.

A system of components specifically developed for multi family and light commercial construction. We call it open joint siding and it offers the most breathable energy efficient option for modern shed customers. Open joint siding provides extra layers of defense.
