In the construction sector, the pursuit of immediate cost savings during the design or building phase—whether through hiring less qualified professionals, using low-quality materials, or modifying construction systems without technical backing—can lead to financial losses and future rework, compromising a building's performance and durability. The Franklin Township Library in Somerset, New Jersey, is a clear example of the consequences of inadequate material choices, particularly regarding energy efficiency and carbon footprint.
During its construction in 2005, the originally specified Kalwall translucent fiberglass-reinforced polymer (FRP) panels were replaced with polycarbonate panels on the roof to achieve an initial savings of $90,000. This seemingly harmless decision quickly proved problematic, resulting in significant operational challenges.
As a highly transparent material that stands up to all but the most extreme of weather conditions, is easily formed into any size or shape, and, once formed, will last for thousands of years, glass is still one of the most innovative and crucial materials used in architecture. Although contemporary building practices allow us to form huge, glittering skyscrapers of glass that rise hundreds of meters into the air, the ancient material’s original purpose – to welcome light into weathertight and secure interiors – remains its most important more than a thousand years on.
As important as glass is to almost every typology of architecture in the form of windows, when it comes to the roof of a building, the use of glass is not so simple. We’ve understood the power and danger of combining light and glass ever since we saw a magnifying glass used to concentrate the heat of sunlight into incredibly high temperatures in children’s cartoons. Under a glass roof, the solar gain can make for uncomfortable internal environments without the correct protective precautions.
Translucency, at its essence, is an optical property that enables the total or partial passage of light through materials, without providing a clear view of the objects behind them. Despite its apparent simplicity, this property has fascinating applications in the architectural field, generating attractive and powerful proposals that play with light without obstructing views.
Traditionally, glass sheets have been the symbolic material associated with transparency, commonly used in the fabrication of doors and windows. However, technological advances in production and the exploration of innovative materials have significantly expanded the opportunities to take advantage of this property in both interior and exterior applications. These advances challenge preconceived limitations and encourage creativity in the development of novel architectural proposals.

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.

After over two decades in the making, the Perelman Performing Arts Center opened to the public on September 19, 2023. The luminous cube-shaped building was designed by the architecture firm REX, led by Joshua Ramus, to become one of New York City’s cultural keystones and the final piece in the 2023 Master Plan for the rebuilding of the 16-acre World Trade Center site. The inaugural season will feature commissions, world premieres, co-productions, and collaborative work across theater, dance, music, opera, film, and more. While only eight stories high, the venue stands out due to its monolithic façade composed of translucent veined Portuguese marble.
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.
In the heyday of high modernism, architects such as Le Corbusier and Mies van der Rohe extolled the aesthetic value of whiteness, which they viewed as connoting purity and simplicity. Mies van der Rohe’s Farnsworth House, for example, paired the stripped-down whiteness of its structural skeleton with expansive floor-to-ceiling windows, using the enveloping natural light to further elevate the already heavenly aspirations of the space. Today, some contemporary architects and designers have evolved the sublime aesthetics of white high modern architecture by using translucent fabric partitions, complementing the purity of the white walls with the fabrics’ ethereal play of light and shadow. Below, we discuss different design strategies for working with white fabrics in this way, and include two examples of projects that have used translucent fabrics in soothing but innovative ways.

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.

When designing a space, architects across the board tout the importance, and even necessity, of incorporating natural light into interiors. This means taking measures to control the quantity of light being let in and its distribution throughout the space.
In the case of residential spaces, where privacy plays a larger role than in public spaces like offices, restaurants, and stores, opaque materials like screens, tinted glass, and other barriers are the go-tos for providing protection and privacy from the outside; however, the privacy that these methods provide often comes at the cost of the space's natural lighting, forcing designers to seek alternative materials that allow for both light and privacy.
Composed of microcell panels, polycarbonate offers various solutions for the use of natural lighting in architectural enclosures. Whether applied to facades, interior spaces or roofs, the benefits of polycarbonate, such as lightness, clean lines, colored panels, and light effects, offer a wide range of design freedom. Microcell panel technology reduces the need for artificial light and favors uniformity in the diffusion of natural light, achieving energy efficient facades and the illusion of spaciousness in interior spaces. Below, we've selected 10 projects that have used polycarbonate as a wrapping material.
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.
