Fundamental Elements of Installation
A facade must meet many requirements, ranging from the observance of technical norms to the solution of static and functional problems as well as desired energy savings. However, it is also true that aesthetic and creative factors are the most visual elements of a building and are often uppermost in the mind of the designer. Technical criteria must, therefore, run parallel to aesthetic criteria, allowing creativity to range without excessive constraints.
Anchor Brackets Are Affixed to the Tile
- To “interface” the tile structure with the substructure so that it is strong and long-lasting, four points are identified on the back of the tile. These points are pre-drilled for the insertion of specifically designed anchors which facilitate attachment of the tile to the aluminum framing.
- The location of the four points will vary according to the requirements of the design.
- A cone shaped hole is drilled and undercut (inverted cone-shape) into the tile in one step by completely automated equipment to extremely tight tolerances. Once the programmed design depth has been reached, a specialized flaring, (wider than the entry diameter) creates the housing for the anchor.
- Once inserted, the anchor expands without creating internal forces on the tile. The anchors and screws are stainless steel. Anchor brackets are then secured with stainless steel self-locking nuts.
Bearing Frame Comprised of Vertical Risers and Horizontal Runners
- A grid of vertical risers and horizontal runners form the bearing structure in this system.
- Vertical framework is comprised of extruded aluminum sections.
- Horizontal runners are secured to the vertical risers with aluminum alloy rivets.
- Brackets allow the coupling of the tile and the bearing substructure.
- The bracket shape exactly complements that of the horizontal runners, featuring a screw adjustment system that allows the tile to be perfectly aligned in the vertical plane during installation.
- A second headless screw allows the slab to be locked to the runner, avoiding any horizontal movement due to side winds on the facade or thermal expansion.
- Only one of the upper brackets is fixed, allowing expansion in one direction only.
Thermal Insulation Is Applied
- The rigid fiberglass insulating panel is specially designed for use in ventilated facade systems.
- Due to the completely inorganic nature of fiberglass, the physical characteristics of the panel will not alter over time, thus guaranteeing constant thermal performance, with no degeneration.
- A fiber scrim covering the exposed face prevents mechanical erosion due to air-flow.
Wall Cladding Elements Are Installed
Wall cladding options in porcelain stoneware are diverse. The use of different finishes - natural, polished, glazed – or a combination of more than one type creates wallscapes truly customized to the designer’s vision. Both in technical and aesthetical terms, porcelain is a superior choice for beautiful, strong and frost resistant walls.
Porcelain stoneware is also a more efficient choice than products like natural stone because it is less expensive, more economical to transport and accounts for 1/3 less weight on the building.
- Tile elements with pre-fitted anchors can be factory-supplied. They are immediately ready for attachment to the brackets.
- When the dimensions of the material to be cut are determined at the construction site, a compact, user-friendly, portable machine is available to accomplish the drilling and automatic insertion of the anchors on-site. In this scenario, the installer has maximum freedom to correct any jobsite variations from the original design.
Maximum design freedom is inherent due to the compatibility of different sizes and the flexibility of tile mounting patterns. Diagonal mounting or staggering of one row of tiles vis-á-vis adjacent ones thus become straight- forward operations. Curved surfaces are covered by becoming polygons with the sizes of the sides being a function of the curvature radius.
