Kerf – Kerf is defined as the width of material that is removed by a cutting process. It was originally used to describe how much material was removed by a saw, because the teeth on a saw are bent to the side, so that they remove more material than the width of the saw blade itself, preventing the blade from getting stuck in the material. Gridworx uses fabricated as six sides sawn with plunge kerfs on horizontal edges.

PES (Pressure Equalized System) – Gridworx manufactures the most advanced pressure equalized rainscreen cladding system by addressing the difference in air pressure across the exterior cladding causing infiltration of air and water. As thunderstorms approach the air pressure in the cavity becomes less than the external air pressure along the building face.The natural equalization of this differential in air pressure causes the wall cavity to literally draw water into it. The basic premise of the rain screen principle is to control the forces that permit moisture into the wall system. Its primary function is to restrict the passage of this moisture through the wall caused by atmospheric induced pressures. Gridworx offers the only system that includes a Vertical Water Blocker to deflect both the kinetic energy and capillary action of rain on the wall plane. This enhancement keeps 95% of the water that might enter the wall cavity through the open joint out of the wall cavity. The louvered openings in this component are designed to allow for the free flow circulation in the wall cavity. Additionally this system allows for quicker drying of water in the wall cavity due to increased air circulation.
Point Load Stress – Stress applied to stone, typically found when using stainless steel bent plate installation clips. The point supported disconnects of this type of installation create point load stress. With the Gridworx continuous aluminum channel support system, the concern for point load stress is eliminated.

The smaller diameter ring of this component is designed with wings to secure its stability and correct placement in the pre-drilled hole. The sleeve protrusion between this smaller diameter and the larger diameter ring is designed to isolate the steel fastener; keeping it from making contact with the sides of the Z Girt. The larger diameter ring isolates the head of the fastener from contact with the top of the Z Girt. With a careful analysis, one will note there is no contact between the metal in the wall cavity and that of the steel studs. This thermally isolated ASHRAE system was designed and approved by SGH Engineering
