The architectural landscape is evolving, and one of the most exciting trends on the horizon is the rise of fabric roofs. These innovative structures offer an alluring blend of aesthetics, functionality, and sustainability. As cities grow busier and space becomes more precious, architects are turning to lightweight materials that not only enhance design but also improve energy efficiency.
Imagine walking into a stadium with a stunning fabric roof that shields you from the elements while allowing natural light to flood in. The future of architecture is bright—and it’s draped in fabric.
Join us as we explore the various options available for modern fabric roofs, delve into custom designs, and celebrate our successful projects.
Fabric Roof Options in Modern Architecture
Modern architecture employs several fabric roof options that provide versatility, energy efficiency, and aesthetic appeal. Popular choices include PVC membranes, PTFE glass fabrics, and other advanced woven or coated textiles designed for durability and sustainability.
Key Features and Architectural Benefits
- Translucency and Natural Lighting: Many fabric roof options are semi-translucent, allowing for natural daylight to penetrate the interior. This can reduce or eliminate the need for daytime lighting, contributing to energy efficiency.
- Thermal Performance: Fabric roofs possess non-conductive properties, which help maintain comfortable interior temperatures by reducing the transmission of heat and cold.
- Lightweight and Customizable: Fabric roofs are much lighter than traditional materials, requiring less structural support and allowing for bold, creative forms. Their modular nature enables highly customized designs for a variety of uses, from sports arenas to public spaces
Lightweight Materials used by Dunn
Dunn is at the forefront of modern architecture, utilizing innovative lightweight materials for fabric roofs. These materials not only reduce structural load but also enhance design flexibility.
ETFE
ETFE (Ethylene Tetrafluoroethylene) is a cutting-edge, ultralight membrane material that delivers outstanding transparency and design freedom for large-span roofs and facades. Its high translucency, low weight, and elasticity allow us to create bright, naturally lit spaces with minimal structural support, reducing steel tonnage and overall embodied carbon.
ETFE cushions and single-layer systems offer excellent durability, UV resistance, and fire performance, making them ideal for stadiums, transit hubs, and landmark enclosures where long-term clarity and low maintenance are essential.
PTFE
PTFE (Polytetrafluoroethylene) coated fiberglass is the preferred solution for permanent tensile structures that must meet stringent building codes and long service life expectations. With high strength, exceptional resistance to temperature extremes and chemicals, and a lifespan measured in decades, PTFE membranes provide reliable performance in demanding climates and critical infrastructure projects.
PTFE’s controlled translucency (typically around 7–15%) delivers soft, diffused daylight while reflecting a large portion of incident solar radiation, helping Dunn design energy-efficient, glare-free environments for public, commercial, and cultural spaces.
PVC
PVC (Polyvinyl Chloride) membranes offer a flexible, cost-effective solution for a wide range of architectural fabric roofs, canopies, and façades. Their adaptability to complex geometries, good weather resistance, and ease of fabrication make PVC ideal for projects that demand both dynamic forms and reliable long-term performance.
With proper formulation and detailing, PVC systems can achieve impressive durability and low maintenance, enabling Dunn to deliver visually striking, sustainable tensile structures that balance budget, speed of installation, and design impact.
MESH
PVC mesh membranes combine shading, ventilation, and visual impact in a single high-performance façade or canopy solution. The open-weave structure allows controlled airflow and daylight while blocking direct sun and rain, enhancing comfort and reducing cooling loads in warm climates.
Available in a wide range of colors and patterns, PVC mesh can become the most expressive component of a building envelope, enabling Dunn to create iconic, branded facades that meet functional requirements for solar control, thermal performance, and occupant comfort.
Dunn Successful Fabric Roof Projects
Fabric roofs have transformed several iconic structures, showcasing their versatility and aesthetic appeal. Our tensile architects share insight on two emblem projects:
Weidner Field
Weidner Field is home to Colorado Springs Switchbacks FC of the USL Championship and is designed as a multifunctional bowl that supports soccer, concerts, and community events in downtown Colorado Springs.
Sitting at an elevation of about 6,035 feet, it is recognized as the highest-altitude professional soccer stadium in the United States, offering a unique matchday atmosphere for up to roughly 8,000 spectators.
PVC canopy design
For this project, Dunn Lightweight Architecture was engaged to design PVC membrane canopies that shade the seating areas without obstructing views of the pitch or the surrounding stadium environment. The lightweight PVC system follows the bowl geometry, integrating cleanly with the primary structure to deliver both visual lightness and effective solar protection for fans throughout events.
Miami Port
The Miami Port project involved designing architectural fabric structures that enhance transit and cargo operations while providing functional and aesthetic improvements to the port’s infrastructure.
The use of PTFE membranes allows for long-lasting performance under harsh coastal weather conditions, including intense sunlight, salt exposure, and heavy rainfall typical of the Miami area.
Material and Design Benefits
PTFE fabric was chosen for its exceptional strength, durability, and resistance to chemical and environmental degradation, making it ideal for the port’s demanding operational context. The lightweight nature of the fabric reduces the need for heavy structural supports, enabling faster installation and cost savings without compromising on structural integrity or safety.
