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

A Holistic Proposal for the Opaque Façade Segment

• r

Universal Substructure System and Technology for Fixing

• f 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.)

• easy and inexpensive to process
• minimum intrusion into the panel
• reliable grip of the fixing components
• allows downsizing of claddings thickness
• better static performance
• possibility of wedge or clasp fixing

various materials - mainly natural stone and ceramics. The rig is designed for productivity and ease of use. It can easily be converted into drilling rig. It is available in mainly three different sizes. Highly efficient, fast milling diamond wheels

• f different sizes (thickness 2-

10mm, diameter 40-80mm) are supplied.

Hole Drilling Application

BILDA slot milling rig is converted into stationary side drilling rig by just reassembling the spindle-and-trolley mobile

• components. It makes holes of 5, 6, 8 and

10 mm in diameter in the sides of cladding panels of various materials - mainly natural stone and ceramics. The holes are produced with precise and clean finish. Standard drill bits of different sizes (5 - 10mm) are used.
