The expert rainscreen cladding technology

total facade solution

BILDA is an innovative technology for assembly of structures and mechanical fixing of cladding panels which comprises the following basic components:
BILD-ing kit. A modular set of square profiles, Q-channeled at corners, and versatile elements that can form various structures through quick dovetail coupling – from flat grids to spatial constructions and entire independent structures. These can incorporate mechanically fixed layers to form cladding skins for facades or other applications. BILDA components are produced from aluminium alloy EN AW 6063-T6.
Cladding method. A precision slot technique that allows for innovative slot-and-blade attachment of the skin elements to the substructure. The precision slot is a minimally invasive cut in the side of the panels that spares their thickness and their strength, respectively. The blades of the fixing clips tie back the panels by penetrating the slots. The ‘slot-and-blade’ connection also allows for even distribution of stress from horizontal load.
Know-how. Assembly rules, detailing, technical data, instructions and methodology, precision slot milling guidelines – all developed through study, modelling, testing and practice.
Slotting machinery. Patented machinery and tools for milling the precision mortise slots in panels by a low-cost cutting process. A range of efficient rigs for the factory and construction site as well as handheld machines is available. These are equipped with cutting discs for all cladding materials.
Features & Advantages
The modular set of elements can be used to just cover walls and create simple cladding layers. It can also help model the cladding layer in a ‘bas relief’ manner or create ‘haut relief’ features and façade elements.
Basic Assemblies
Vertical strut assembly - mainly for ‘landscape’ orientation of the cladding panels.
Horizontal strut assembly - mainly for ‘portrait’ orientation of the cladding panels.
Low Cost
BILDA accomplishes structures of excellent strength-to-
cost ratio due to its integrity. Labour time is saved through quick connections. Panel thickness may be reduced via the flat precision slot. Slots are the easiest cladding panel mortise due to machining through cutting.
Pre-planned solutions
For feature nodes within the cladding areas (corners, reveals, copings, etc.) and for interface fragments (to curtain walls, windows, doors, roofs).
A wide range of fixing clips of different size and shape can support panels from all materials, of different thickness and configuration. The clips, in addition to the preferred ‘slot-and-blade’ method, can handle all known fixing methods - the ‘hole-and-dowel’, ‘undercut’ of different types, etc. These can be employed next to each other.
Complies with regulations
BILDA cladding technology has been designed and is produced in accordance with European building regulations:
▪▪ EN 1990: Eurocode – Basis of Structural Design
▪▪ EN 1991: Eurocode 1 – Actions on Structures
▪▪ EN 1999: Eurocode 9 – Design of Aluminium Structures
▪▪ DIN 18516-1:2010-06 – Cladding for external walls, ventilated at rear
