Introduction:

Mechanical cladding systems play a pivotal role in the construction industry, providing not only aesthetic appeal but also serving as a protective layer for buildings. One critical aspect that often goes unnoticed is the impact of thermal conductivity on a building’s energy efficiency. In this article, we will delve into the two main mechanical cladding systems offered by Technik Engineering Industries and explore how material choices, particularly thermal conductivity, can influence the overall energy performance of a structure.

Understanding Mechanical Cladding Systems:

Technik Engineering Industries offers a comprehensive range of mechanical cladding solutions, with a focus on two main categories: the Bracket systems and the Framing systems.

Bracket System:

Primarily employed with structural base materials and moderate cavities behind the cladding, the Bracket system comprises Z and M shaped brackets, shelf angles, L-brackets for restraints, and other variations. The common thread among these brackets lies in the material, with options including stainless steel grade 316 or stainless steel 304, hot-dip galvanized for larger sectioned plates.

Framing System:

Designed for large panels and non-structural base materials, the Framing system excels in accommodating large cavities. This system is further subdivided into:

1. C-channel systems, constructed from stainless steel or hot-dip galvanized materials, often utilized with extension arms and pins or brackets from the Bracket system.

Distinguishing Factor: Connected Area with the Base Material

The primary differentiator between the Bracket and Framing systems lies in their connected area with the base material. The Bracket system necessitates more connected areas, especially when used with structural base materials and smaller to medium cavities. In contrast, the Framing system boasts minimal connected areas, establishing a direct connection from slab to slab with strategically placed holders and the least amount of connections for restraints.

Additionally, it is essential to note that when the connected area is reduced or minimized, the thermal conductivity is also diminished, owing to the reduction in thermal bridging. This is a crucial aspect in optimizing energy efficiency, as minimizing thermal bridging helps create a more effective thermal envelope for the building. The Framing system’s design, with its focus on minimizing connected areas, aligns with this principle, contributing to enhanced thermal performance and overall energy efficiency in construction projects.

Thermal Conductivity Challenge:

An inherent challenge in the Framing system is the higher thermal conductivity associated with aluminum compared to steel. While aluminum minimizes connections, its thermal conductivity is addressed through a thoughtful solution implemented by Technik Engineering Industries. Rubber is strategically placed behind the holding sets and restraints, acting as an effective thermal insulator. This innovation mitigates the transfer of heat from the mechanical cladding system to the building, aligning with the company’s commitment to energy efficiency.

Conclusion:

In the quest for the most efficient mechanical cladding system, the interconnected factors of material selection, design considerations, and thermal conductivity become paramount. Technik Engineering Industries not only provides a spectrum of options but also addresses the challenges posed by thermal conductivity through innovative solutions, ensuring that their mechanical cladding systems contribute to enhanced energy efficiency in modern building designs.
