Problems solved by technology

However, the lack of permeability / venting to either water vapor or air makes this system problematic.
However, these systems allow water to penetrate, causing water damage which is also problematic.

[0056] Referring again to FIGS. 3 and 4, the features in this exemplary embodiment of the horizontal and vertical joints work to prevent water from penetrating to the architectural wall. This is proven by the tests represented in the examples below.

[0057] Air infiltration, water penetration, and structural performance tests of the system installed in a laboratory test chamber were performed. Wall Assembly A was tested on Apr. 8, 2005, which Wall Assembly B was tested for water penetration in accordance with ASTM: E 331 on Apr. 22, 2005, and for water penetration in accordance with ASTM: E 331 but modified to monitor air flow as openings were cut in the back-up wall on May 6 and Jun. 7, 2005. The following comments describe the test procedures and results for each wall assembly.

Abstract

A wall panel joint apparatus and a system using same is disclosed. The wall panel joint includes a perimeter joint body having a predetermined size and shape. The perimeter joint body floatably attaches to at least two wall panels. Embodiments include where the wall panel joint includes zero, one, two, three or more compartments. Also, some embodiments include a rainscreen clip that forms an additional compartment. The system includes at least two wall panel joints that attach the wall panels to an architectural wall. At the point of intersection of the joints, the joints are mitered. The system also includes a wall attachment device and a means for attaching the joint to the wall attachment device. The system is a liquid water impermeable, air permeable and water vapor permeable system, providing a ventilated, waterproof wall panel attachment joints for use in same.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] The present application claims the benefit of Provisional Patent Application Ser. No. 60 / 645,101 filed Jan. 20, 2005 and Provisional Patent Application Ser. No. 60 / 655,370 filed Feb. 23, 2005, which are incorporated herein by reference.TECHNICAL FIELD [0002] The present invention relates to wall panel joints and systems for wall panel application. BACKGROUND INFORMATION [0003] Architectural panel has been in use for many years. All architectural panel systems can be classified into two major categories, namely, “face-sealed” and “vented rainscreen” systems. [0004] Face sealed systems include all systems with joinery that make use of sealant in the joinery whereby the system is substantially nonpermeable to either water or air. Achieving complete face seal is the very basis of all face seal systems. Sealant can be caulking, gasket, or other sealant of similar function. However, the lack of permeability / venting to either water vapor or ai...
