Opaque Faade Segment or Universal Substructure System and - PowerPoint PPT Presentation

A Holistic Proposal for the Opaque Façade Segment or Universal Substructure System and Technology for Fixing of Ventilated Claddings and Modelling of Façade Features August 2019

Building envelope industry has evolved dynamically in the last • decades. Glazing enclosures developed in a technical way to reach a • state of certain maturity nowadays. Opaque enclosures responded with craftsmanship oriented, • improvised solutions. 2

Inadequate application of the potential of different cladding • materials. Insufficient compatibility between different cladding and • enclosure materials. Sustainability requirements where opaque enclosures are • efficient. Demand for diversity and “ materiality ” in facades' • appearance. Fragmentation resulting from the multitude of techniques and • methods in the cladding sector. 3

Facilitate the usage and increase the share of ventilated claddings • Devise a universal system/ technology regarding: • a. all types of cladding materials b. all methods of clamping the panels Systemize the existing cladding culture • Enrich cladding activity with new functions like façade volume modelling, grid • pattern diversification The result - BILDA - Universal Substructure System and Technology for Fixing of Ventilated Claddings and Modelling of Façade Features 4

• Universality – applicable for skin elements of any material (stone, ceramics, HPL, metal, FCB, GFRC etc.) - facilitates design and engineering. Installation of the whole envelope by a single contractor becomes feasible. 5

• Downsizing of cladding’s thickness - specific fastening intrusion (precision slot) allows thinner skin elements to be applied. A range of instruments and machines pertaining to BILDA technology assures low- invasive flat “sockets” in panels’ side edges

• Lighter subframe – sophisticated structural optimisation of subframe’s components achieves an excellent strength-to-weight ratio 7

• Fast assembly – revolutionary dual tongue & groove peripheral fastening ensures easy assembly with minimised errors and low installation costs 8

• System solutions for various facade elements – suitable for different cladding areas (corners, reveals, copings, etc.) and for interface sections (to window, to curtain wall, etc.) 9

The Precision Slot • easy and inexpensive to process • minimum intrusion into the panel • reliable grip of the fixing components • allows downsizing of claddings thickness BILDA Slot milling machine 50 mm half - moon shape • better static performance 2  5 mm wide • possibility of wedge or clasp fixing Slot Pin Clasp fixing 14

Slot Milling Rig BILDA precision slot is easy and inexpensive to mill with our patented stationary or handheld slot-milling machines. Equipment is light and compact, with high performance that guarantees initial low cost investment and fast return. 15

Slot Milling Rig • Slot Milling Rig Description Hole Drilling Application The stationary slot milling rig produces BILDA slot milling rig is converted into narrow half-moon precision slots in the stationary side drilling rig by just sides of cladding panels of various reassembling the spindle-and-trolley mobile materials - mainly natural stone and components. It makes holes of 5, 6, 8 and ceramics. The rig is designed for 10 mm in diameter in the sides of cladding productivity and ease of use. It can panels of various materials - mainly natural easily be converted into drilling rig. It is stone and ceramics. The holes are available in mainly three different sizes. produced with precise and clean finish. Highly efficient, fast milling diamond Standard drill bits of different sizes (  5 - wheels of different sizes (thickness 2- 10mm) are used. 10mm, diameter 40-80mm) are supplied. 16
