Gridworx - Mechanical Kerf

Mechanical Kerf

ultraThe patented Gridworks mechanical kerf system utilizes a faux kerf for attachment to our continuous horizontal rails. The Mechanical Kerf Anchor & Gridworx Mechanical Kerf Lock Washer are attached to the back of the cladding panel using a KEIL, FISCHER or T-31 undercut anchor. This system is an effective option for anchoring thin cladding when saw kerfs are not an option, such as ultra-compact surfaces or 20mm thick natural stone. When used in conjunction with our saw kerfed system, the mechanical kerf system can achieve clean, exposed edges at wall transitions.

All of our anchoring systems are designed to be mounted to the building substrate via our standard Thermally Broken Components providing space in the wall for insulation and adjustability.

These mounting systems allow for a precise and far more technical way of mounting wall panels thereby allowing for the introduction of mixed media presentations.

This 12mm UCS (Ultra-Compact Surface) material is augmented with a saddle clip creating a faux Kerf for attachment to a continuous horizontal rail. The Mechanical Kerf Anchor & Gridworx Mechanical Kerf Lock Washer are attached to the back of the stone using a KEIL 8.5mm undercut anchor.

A T31 attachment is utilized on natural stone panels of greater thickness. (1" - 2")

With these anchors combined with today’s contemporary cladding systems, the panels can be set extremely close together creating technically accurate and well defined joints.

Thermally Broken Subframe

A thermal break or thermal barrier is an element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials.

GRIDWORX strives for the best properties of our materials to provide a thermally efficient, energy-saving product that prevents thermal bridging in structural connections. These thermally broken aspects of our Gridworx mechanical stone cladding system are shown below is a section detail of our ASHRAE 90.1 qualified system including our Gridworx sleeve washer and Thermal Sleeve isolating back plate.

Please note in the section detail the item described as, “1/8” Thermal Break - Thermal Shoe.”This component is best described as a plastic footing that functions as an insulator between our aluminum Z Girt and the substrate (typically Dens Glass).This is an impact resistant, high quality extruded component made from ABS SP-9010 plastic. Further, this material is heat resistant.

Thermally broken washer GridPlanxThe second item is referenced as, “Thermal Isolated Sleeve Washers.”This sleeve washer is made from NORYL Resin SE1GFN PPE+PS blend. 30% Glass reinforced Non-brominated, non-chlorinated FR system.

Please note the application of this component (drawing above). This washer is designed to first be placed in the pre-drilled hole in the Z Girt.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.This explanation should make it easier to follow in conjunction with a careful review of the attached section drawing.

This system was designed and approved by SGH Engineering.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 is truly a thermally isolated system.

Make good Better

A proposed building design is demonstrated through building energy simulation to use less energy than a baseline building built to ASHRAE 90.1 specifications. All building components must be qualified by individual testing.Gridworx worked closely withSimpson Gumpertz & Heger, an independent engineering firm, in the development of this system. It was deemed to meet or exceed performance standards in Thermal Performance, Air Barrier Performance and Condensation Potential.
