Requirements & Evaluation criteria

Detachment Capability & Installation Optimization: Systems must allow for the removal of facade cladding/ panel without causing damage to either the facade materials or the underlying structure. At the same time, individual fastening parts such as screws or dowels must not be reusable.

Modularity: Systems should be modular, allowing for easy adjustments and modifications as construction needs evolve.

Strength, Stability & Durability: Solutions should provide secure attachment and structural stability comparable to traditional fastening methods & ensure that they can withstand environmental factors, aging, and wear without compromising performance. Moreover, properties such as impact strength and compressive strength, wind tightness/weather tightness (joints) are also relevant.

Thermal Performance: Solutions should achieve a maximum thermal transmittance (U-value - Punctual thermal bridges according to DIN EN ISO 6946) of 0.25 W/(m²·K) or lower, minimizing heat transfer between facade and structure. Materials used in the systems should have low thermal conductivity, contributing to improved energy efficiency. Example for Isolink with 0.24: https://www.schoeck.com/de/isolink#downloads

 

Compliance with the Publication of the Administrative Regulation Technical Building Regulations 2023 (available only in German): https://www.dibt.de/fileadmin/dibt-website/Dokumente/Referat/P5/Technische_Bestimmungen/MVVTB_2023-1.pdf

Important parts of the administrative regulation for technical building regulations

DIN 55699: This standard applies to the application and processing of external thermal insulation composite systems (ETICS) with insulating materials made of expanded polystyrene rigid foam (EPS) or mineral wool (MW) with reinforced base coat and finishing render or flat facing.

DIN 18516-1: Exterior wall claddings, ventilated - Part 1: Requirements, test principles

DIN 1055-1: Wind load on structures

DIN 1055-5 | 2005-07: Actions on structures - Part 5: Snow and ice loads

Flexibility: Fastening systems should accommodate variations in building designs, enabling their application in both residential and commercial settings. The system should therefore be adaptable and have a broader application range. The properties such as adaptability to the surface (balancing of substrate unevenness) must also be considered.

Ease of Installation & improved handling: Fastening systems should be user-friendly, enabling construction teams to implement them efficiently. Hereby it is preferable to consider the reduction of the working steps.

Regulatory Compliance & Increased application safety: Solutions should adhere to relevant construction codes and regulations, ensuring safe and compliant implementation.

Fire Resistance: The fastening systems should comply with fire safety regulations and demonstrate resistance to fire propagation.

Functionality Demonstration: To comprehensively assess the viability of the proposed innovative facade fastening systems, a fundamental requirement is to vividly demonstrate their functionality. This involves employing effective methods to visually and practically depict how the systems operate in practical settings.

Ecological Sustainability: The solutions developed should take into account and address the ecological compatibility of the materials.
