Water resistive barrier siding.

Keeping water out of the interior. In fact by varying. The layer beneath the siding the water resistive barrier or wrb is what will protect the plywood or oriented strand board osb sheathing from any water that sneaks in. This article series discusses best practices construction details for building exteriors including water and air barriers building flashing products installation wood siding material choices installation vinyl siding stucco exteriors building trim.

A rain screen is constructed by fastening wooden boards vertically on top of the weather resistant barrier wrb to provide an air gap between the building and the siding creating a drainage plane. The latest tip for creating an airspace between siding and the water resistive barrier wrb is simple and inexpensive. Allow for drying of the exterior. Steel siding is exceptionally resistant to high winds and the impact of flying objects.

It is designed to prevent water from reaching building components that could be damaged by moisture. Prevent air flow in out of the interior. Weather barriers or more accurately water resistive barriers keep bulk water away from vulnerable building components and allow walls to dry at the same time. Water resistive barrier defined.

Steel siding itself is waterproof. It sits just under the siding. Water infiltration can lead to rot of structural elements mold and poor indoor air quality. However the product is susceptible to allowing moisture intrusion into the wall system through condensation and water infiltration.

This article explains the need for water resistant barriers on building exterior walls and explains the concept of a rain screen. A water resistive barrier wrb is a material installed between the sheathing or studs if there is no sheathing and the siding. A proper barrier will be responsible for doing the following. A siding rain screen is an important part of siding replacement and siding repair.
