Timberflex and Flexboard can be attached with the use of glue and staples to a framework. This framework should consist of horizontal ribs to attach the material. In most applications at least three ribs are recommended. Where the height of the framework is over 4', it is recommended that a horizontal support rib be used every 15 to 18 inches to provide the necessary support. (Fig. 1 and Fig. 2)

Vertical support ribs are not needed to attach the Timberflex or Flexboard. Vertical ribs should only support and position the horizontal ribs. It is recommended that any vertical ribs be set back slightly from the horizontal ribs so they will not interfere in the forming of the material. Only attach to a flush vertical rib when forming a seam.
