Benefits of technology
The patent text describes an improved system for installing cladding assemblies on exterior walls that increases the wind load resistance without adding more fasteners. This is achieved through a cladding reinforcement system that is easy to use and can be placed at strategic locations in the cladding assembly. The system uses reinforcement anchors that are mounted on the cladding panel, with one or more fixing indicators for locating the anchor. The use of reinforcement anchors results in a significant improvement in wind load resistance, increasing the wind load until failure by at least about 55% compared to using screws without the reinforcement anchor. Overall, this system provides a more robust and durable cladding assembly.
Problems solved by technology
In either case, the cladding material is released from its installed position because of the concentration of wind load pressure on the fixings, leading to damage to the cladding material and possible other damage to the structures and substructures around the cladding material.
Screw fixing of cladding materials to substructures has been used to improve the wind load capacity of wall assemblies, but screw fixing is more expensive and slows the installation rate.
Screw fixing increases the holding power of the shank but the head may still be pulled through the cladding, once again due to the concentration of wind load pressure on the fixings.

examples
[0053]The following examples are provided to demonstrate the benefits of embodiments of a cladding reinforcement anchor. The examples are discussed for illustrative purposed and should not be construed to limit the scope of the disclosed embodiments.
[0054]A cladding material, HardiPlank® Lap Siding complying with ASTM C1186 Grade II Type A, was attached with embodiments of the above described cladding reinforcement anchor. The cladding material was 5 / 16 inch thick by 8.25 inch wide. The cladding clip was 2 inch wide. The first leg was 1⅛ inch long and the second leg was 7 / 16 inch long. The thickness of the first leg was 24 gauge. The depth between the first leg and the second leg was 5 / 16 inch. The example show a comparison between a cladding material attached with a cladding reinforcement anchor and a cladding material attached with a nail. The results of the examples are shown in Table I.

A cladding reinforcement system and method for attaching a cladding material to a substructure are provided in this disclosure. The cladding reinforcement system utilizes a cladding reinforcement anchor to provide a large surface area for resisting the forces in high wind applications. In some implementations, the cladding reinforcement anchor has a flat front surface that is adapted to be fastened to the cladding panel. The front surface of the cladding reinforcement anchor is sufficiently flat so that it can be sandwiched between two cladding panels without creating any visible space between the cladding panels. In some other implementations, the cladding reinforcement anchor includes a web having first and second spaced apart edges configured to define a predetermined width for locating the cladding reinforcement anchor against an upper edge of a cladding panel. Fixing indicators can be located on the flat front surface to provide targets for nails or other fasteners.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of United Kingdom Patent Application No. GB1112337.9, filed Jul. 18, 2011, and is incorporated by reference herein in its entirety.BACKGROUND[0002]1. Field[0003]The present disclosure generally relates to systems and methods for installing cladding assemblies.[0004]2. Description of the Related Art[0005]Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of the common general knowledge in the field.[0006]Many cladding materials, such as timber, vinyl, and fiber cement have been used in plank or weatherboard form to construct exterior wall assemblies on buildings. Typically, each piece of such cladding material is installed so that its lower edge covers the fixing positions of the previously installed piece. The location, strength, and configuration of the nail provide the resistance of the wall asse...
