Polycarbonate: The Latest Architecture and News

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.

Sustainability is much more than simply deciding for or against a specific product. It is a concept that must be integrated into the way we build and design architecture, as well as the intelligent use of existing buildings and their potential renovations. From a sustainability perspective, demolishing an old building is just as unsustainable as building a new one. Both use large amounts of embodied energy that can be avoided when all planning parties consider new ways of working and collaborate more closely.

In this sense, the efficient use of raw materials and the reduction of waste for reuse is essential. Polycarbonate in façades, for example, has a life cycle of at least 20 years on average and can be recycled and reused in many ways, thus doubling its useful life until it can no longer be usefully recycled.

The use of translucent materials in Brazilian architecture has been a growing trend in recent years. Translucent laminated glass, polycarbonate and acrylic are just a few of them. They have different advantages and disadvantages regarding cost, impact resistance, and thermal and acoustic insulation. What outlines the common benefit between them is the constant dialogue they provide between interior and exterior.

Sustainability needs to go further beyond inspiring speeches and promises, with visible, concrete actions. In order to see this change, it is essential for individuals, companies and governments to take responsibility and act in a sustainable manner in their daily lives and practices. By taking into account the environmental and social impacts of their decisions and seeking more conscious and responsible alternatives, they can take steps to ensure a sustainable future for the next generations. In the construction industry this is even more urgent. Responsible for a large amount of solid waste and greenhouse gas emissions, it is essential for this industry to adopt sustainable practices, such as recycling, to minimize environmental impacts.

However, even though product recycling processes have significantly advanced in recent years, there are still certain challenges associated with the use of recycled materials. This is due to a variety of factors, such as performance and durability, or even due to the difficulty of obtaining suitable raw materials. But there are also successful examples that show the possibilities of recycled materials.

In architecture, the concept of daylighting refers to when buildings allow natural light inside to provide a number of benefits, from enhanced visual comfort and productivity, to improved health and higher energy savings. However, to reach optimum levels of sunlight, reaching a balance is key; while too much can produce an uncomfortable glare and tremendous amounts of heat, too little can lead to health deficiencies and a greater dependency on artificial lighting. In that sense, the qualities of polycarbonate panels are unmatched, becoming an attractive choice for facades and roofs by achieving a soft, diffused light with varying levels of transparency, brightness and opacity.

Whether blending in or standing out, embodying transparency or solidity, expressing coarseness or softness, a façade is the medium through which we engage with architecture. It tells a story and can often set the tone for the rest of the interior. But apart from defining a purely visual experience, a building’s envelope must also be practical, durable and have the ability to properly manage natural lighting and ventilation needs. After all, by being the point of contact with the outside, it is responsible for mitigating sounds and providing protection from climatic conditions, such as wind, rain, heat and humidity. Therefore, when designing a facade, it is important to consider a balance between performance and a beautiful aesthetic. Of course, many materials successfully meet these criteria. But when it comes to creating a comforting, light-filled ambiance while ensuring resistance, ease of installation and versatility, the properties of translucent polycarbonate panels seem to be unparalleled.

Translucent polycarbonate panels boast unique and striking aesthetics while simultaneously maintaining efficient functionality. They can add depth and color to a façade and may adapt to meet a wide range of performance requirements, from temperature resistance to impact resistance to UV protection and more. Rodeca, a leading company in the polycarbonate panel industry, offers high-quality products with high customizability vis-à-vis colors, transparency levels, treatments, profiles, sizes, joint systems, and more. Below is a detailed list of these many options, accompanied by diagrams and installation steps. We also discuss several case studies where polycarbonate facades have been used to great success, taking full advantage of the options available alongside the intrinsic aesthetic qualities of the translucent panels to complement and elevate their designs.

Polycarbonate has become an alluring alternative to glass in facades, as it has different levels of translucency and can provide optimal transmission and diffusion of light. Moreover, it is light, flexible, recyclable, durable, resistant to impact, and includes UV protection, in addition to resisting temperatures between -40°C and 115°C. But beyond its functional properties, this thermoplastic also provides wide-ranging aesthetic opportunities, allowing architects to create unusually dynamic and expressive facades.

Diversifying the materials of an interior space can greatly improve its depth and visual interest. At the same time, adding partitions or other delineations of internal space can help organize flow, circulation, and visibility. Polycarbonate, a type of lightweight, durable thermoplastic, is an excellent medium for both functions.

In its raw form, polycarbonate is completely transparent, transmitting light with nearly the same efficacy as glass. However, it is also lighter and stronger than glass and tougher than other similar plastics such as acrylic, polystyrene, ABS, or nylon, making it a good choice for designers seeking durable, impact and fire resistant materials that still transmit light. Like glass, it is a natural UV filter and can be colored or tinted for translucency, yet it is also prized for its flexibility, allowing it to be shaped into any size or shape. Finally, it is easily recyclable because it liquefies rather than burning, making it at least more environmentally friendly than other thermoset plastics. For example, recycled polycarbonate can be chemically reacted with phenol in a recycling plant to produce monomers that can be turned back into plastic.

Translucent facades are light glazing panels used on the exterior of buildings, protecting the structure from weather damage, dampness, and erosion. Its composition of polycarbonate microcells creates a soft, naturally diffused light with a wide range of possible colors, brightnesses, and opacities.

By fixing these panels in place with concealed joints, it’s possible to hide unsightly building elements and assist in protecting users from harmful UV rays, while also ensuring maximum thermal conduction. Individuals who use them will notice a reduction in energy bills because they use the sun’s natural light to heat and illuminate buildings, creating very attractive indoor environmental conditions for different uses.
