Therefore a black housewrap enhanced with uv resistance is a perfect component for an open joint rainscreen cladding system. A zip wall sheathing system is added over the building envelope as an air and water resistive barrier these wall panels install in fewer steps than a traditional housewrap so that the building is finished sooner. Instead they re deliberately spaced a frac tion of an inch apart which lets air circu late even more freely than it does behind a conventional rainscreen application. The design concept relies on the performance benefits of a rainscreen which is a gap behind cladding that facilitates drainage and drying.

This paper discusses the implications of open joints for the performance of rainscreen systems. You may have to register before you can post. Called open joint rainscreen it s made up of siding courses that aren t over lapped or butted together in any way. Recent trends in the design of exterior claddings have seen an increase use of open jointed rainscreen cladding systems.

In the seattle area where i work we get a lot of rain. 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. An open joint wood rain screen is a construction method that uses wood siding as the outer rain screen layer creates a wall cavity space between the back of the siding and the outer building envelope and has an open joint in the wood siding to allow for ventilation. We call it open joint siding and it offers the most breathable energy efficient option for modern shed customers.

A system of components specifically developed for multi family and light commercial construction. The downside of the open joint design is that areas of the water resistive barrier are left exposed to sunlight. With the air gap between the exterior siding panels and the structure a solar heat barrier is created making the system viable not only in wet climes but in sunny ones as well. If your project calls for a panelized look the reveal panel system offers the design flexibility you need.

The reveal panel system by james hardie can be utilized to create an effective modern durable panelized look.
