2 DESIGN & AESTHETICS The Anchor Facts The anchor as developed for mechanical, non adhesive concealed anchoring for different façade cladding materials. The anchor is used orldide in the façade industry for rain screen, all cladding, exterior and interior façades. The aesthetics of the façade face is not compromised by any visible fastening components. Positioning of concealed anchors on the back of the panel can be selected ithout restrictions. A ide range of alternatives is made available as to the quality and design of the material. The façade performance ill be more effective and in tune ith the requirements of specific materials. Appearance The façade of a building provides a unique appearance. Designers can imagine many possibilities ith different façade materials but they feel that their ideas are impractical due to restriction in anchoring. The installers of delightful and impressive façade materials are enabled by the concealed anchoring method to achieve the designer s vision. There are no limits to creativity. Whether elegant, traditional, modern, delicate or unconventional even the boldest façade designs can be implemented. The anchor is the perfect choice for architects and designers hen specifying thin materials and non visible attachments. Maintenance and Replacement No soiling or dirt and rust streaks on the face of the façades as the attachment components are situated at the rear. Damaged or unanted cladding material is easily replaced ithout removing or damaging surrounding panels. anchors can be reused to replace façade panels.

3 APPLICATION & CONSTRUCTION Various Cladding Materials More than 50 different types of materials may be used ith the concealed façade attachment. Regardless of material or thickness - all ith the highest degree of safety. Dimensional stone ith a thickness from 5 or 6 cm or 2 2 ¼ inches are standard for façade cladding and for the use ith anchors. Natural Stone i.e.: Granite, Marble, Lime Stone, Sandstone, Jura Stone and Slate ith a minimum thickness of 20mm / ¾. Ceramic and Porcelain tile starting ith a thickness of: 7mm, ¼. Man Made Cladding Panels from Stone and Polymer Cement, Crystallized or Bio Glass, Fiber Cement, High Pressure Laminate, Solid Surface Material, starting ith 8 mm, 3/8 in. The load on the foundation and the building is substantially reduced by using thinner, lighteight panels for the substructure. Construction Time, Labor and Shipping The system drastically reduces the ork involved as feer holes are required and creates economic advantages by generally alloing thinner panel s to be used, particularly if rare and expensive cladding material is requested. Thinner panels, cost less for shipping, handling and installing. Quick, simple and safe The undercut holes shall be drilled at the plant or orkshop to guarantee precise spacing of the drill holes. The anchors and hanger attachments ill be installed at the job site, this avoids damages during handling and transportation in addition to saving time and labor. Anchor Drill Machine The drilling of the undercut hole is archived using the Drilling machine or a CNC machine ith drill bits. Different drill bits for different materials (et and dry drilling) are available.

4 ADVANCED TECHNOLOGY The Undercut Hole For the application of the anchor, a mushroom like hole is drilled into the material using the patented undercut method. The diameter of the undercut hole is larger as the cylindrical channel hole. The patented drilling technique carries out the cylindrical and undercut drilling in one step ith only one tool. Speedy performance - Drilling time for a 15 mm deep anchor hole, is less than 10 seconds. Drill Undercut Finished Hole Insert Anchor Insert Bolt The Concealed Anchor A anchor consists of to parts: Anchor and matching bolt. anchors are made from high quality A4 stainless steel. The anchor geometry matches the undercut hole and ensures a stress free attachment to the material. Extreme climate changes such as heat or freeze contribute to different expansion or shrinking of the cladding materials. While these factors can cause damage ith traditional cladding systems, the stress free fit of the anchor eliminates damage of the façade panel. Selection of the correct size anchor and bolt: h S = 4,0mm h S = 5,5mm h S = 7,0mm h S = 8,5mm h S =10,0mm h S =11,5mm h S =13,0mm h S =15,0mm h S = Insertion depth Other dimensions on request. As thicker the cladding material, as longer the anchor may be. Alays the longest anchor available is selected; this ill increase the load factor (Pull out force). The length of the anchor bolt depends on the anchor length, and thickness of the attachment to the anchor. For additional technical information please visit.tile-eze.com.

5 SAFETY & PERFORMANCE Variance in Cladding Material Thickness Tolerances in panel thickness are simply compensated for in a one step drilling task. The anchoring method allos for adjustment of up to 5 mm in thickness difference of the cladding material typical for natural stone or manmade cement panels.

6 SUPPORT vs. DIRECT ANCHORING Anchor With Support Structure The support structure is the static link beteen the structural external or internal all and the façade cladding. Aluminum and ood or a combination of them are available as materials for the support structure. Aluminum has prevailed in the majority of cases. Aluminum support structures can be adjusted in three dimensions and lie against the building structure free from stress. Any uneveness and all projections can be compensated to achieve a perfect horizontal and vertical alignment. Aluminum support structures can also be highly effectively integrated into the lightning protection system, even if the cladding is non-conductive. ign specializes in rainscreen Vertical Maximum possible pull-out loads: Comparison of the systems:wall Bracket Doel Load displacement graph: (Performance factor 2-7 higher for than doel) C-Channel Adj.
