In the contemporary context, global warming has marked a turning point in the way we think about architecture. We are witnessing record temperatures on our planet and a challenging panorama in many large cities, characterized by heatwaves and, in some cases, more severe winters. These circumstances have triggered a cycle in which the demand for heating and cooling systems increases, which, in turn, translates into higher energy and operating costs for buildings.
Given this situation, it becomes imperative to design energy-efficient buildings to reduce both the environmental impact and the associated costs. One of the strategies to achieve this is to properly plan the facade, which, serving a function similar to the building's skin, can help reduce the energy required for heating and cooling. In this context, the polycarbonate panels developed by Rodeca contribute to the energy efficiency of buildings, in addition to their lightweight, slender construction, and translucent aesthetics.
Features and Architectural Applications of Polycarbonate Panels
Translucent building elements combine effective thermal insulation and translucency to create a striking visual appearance in architecture. Made of thermoplastic polycarbonate, the panels are particularly lightweight, making them suitable for retrofit projects of any scale or complexity. Their low weight also helps prevent any structural issues, and their co-extruded layer protects against UV rays, ensuring long life and durability. These panels find diverse applications, from interiors to exteriors, where they are especially suitable as facade and roofing solutions for industrial and commercial buildings.
The structure of the translucent building elements is composed of several layers that form air chambers acting as multi-level insulators, which reduce heat transmission. Depending on the specific project requirements and the energy demand in the building, it is possible to use panels that have from four to twelve layers. In this manner, the multi-layer structure effectively minimizes heat transfer through the facade. Furthermore, polycarbonate possesses a naturally low thermal conductivity in comparison to materials like glass or metal.
Technical Characteristics and Load-Bearing Structure
In a vertical installation scenario, the 60 mm thick translucent construction elements achieve a heat transmission coefficient (U-value) of 0.75 W/m²·K, reducing heat loss and contributing to a comfortable indoor environment.
In addition, the inherent lightness of the material allows translucent building elements to generate less compressive and tensile stress on the surrounding materials. The polycarbonate panels and their aluminum frame system are significantly lighter compared to other traditional facade framings in materials such as metals or wood. As a result, the lightweight plastic panels are easy to handle and install, reducing costs and effort in on-site execution.
Translucency, Optimization, and Aesthetic Qualities
Since the width of the panels can be customized for each project, there is significant potential for savings through load-bearing structure optimization. With Rodeca facade systems, it is possible to glaze large surfaces while maintaining an external appearance with fewer joints. The optimization in the use of materials makes them a cost-effective solution for the construction of energy-efficient facades.
To enhance their characteristics, translucent polycarbonate panels can also be used in conjunction with thermally broken aluminum framing systems. This reduces heat loss in the building during winter and minimizes heat transfer from the exterior to the interior during summer, a beneficial condition in the contemporary urban context. Additionally, aluminum, like polycarbonate, is very lightweight compared to other building materials, such as steel, while maintaining the same strength and stability.
In addition, their translucency allows natural light to enter without causing glare, making it an optimal way to naturally illuminate interiors, enhancing the well-being of its inhabitants. Consequently, the need for artificial lighting and energy is reduced, demonstrating how polycarbonate panels contribute to a design that makes conscientious and efficient use of resources.
Translucency, a multidisciplinary concept, has fascinated scientists, designers, artists, and philosophers throughout history, spanning fields as diverse as physics, architecture, and art. In contemporary architecture, the research and development of new materials has transformed traditional conceptions. Not only technical capabilities but also ecological impact, thermal qualities, lightness, and other aspects are now assessed.
In this way, Rodeca's translucent polycarbonate panels exemplify a material that combines striking aesthetics with lightness and outstanding ecological characteristics. This is particularly relevant in the current context of energy-efficient building design, aiming to reduce both environmental impact and energy costs.
