Tensile membrane structures are lightweight building systems where a flexible membrane is held in tension by cables, masts or compression rings. Unlike traditional buildings that rely on compression and bending, these structures carry only tension and therefore use minimal material to span large distances. They are most often used as roof systems because they can economically and attractively cover large spaces; common applications include sports facilities, warehouses, storage buildings, and exhibition venues. Modern tensile membranes also form entire buildings, temporary pavilions and spectacular canopies that redefine public spaces.
The performance of a tensile structure depends largely on its membrane. PVC‑coated polyester is widely used for exterior canopies because it offers excellent strength, flexibility, translucency, and a design life of 15–20 years. PTFE‑coated glass cloth provides greater durability (30+ years) and is chemically inert, moisture‑resistant and low‑maintenance. Gore Tenara (weldable PTFE) combines strength, flexibility and longevity, making it ideal for demountable or retractable canopies. ETFE films can be used as single‑layer sheets or inflated cushions to provide good insulation and aesthetic effects.
A tensile membrane system consists of a flexible membrane tensioned between compression elements such as masts, arches or rings and supported by cables. Because the membrane is kept in tension, it does not require heavy framing and can span large distances with minimal material. The structure’s form is derived from the pre‑tension applied during installation and the pattern of cables, resulting in graceful curves and surfaces. The membranes’ translucency creates softly diffused natural light during the day and an ambient glow at night.
Our custom tensile membrane structures are used in a wide range of sectors:

A tensile membrane structure is a lightweight building system in which a flexible membrane is held in tension by cables, masts or compression rings. It carries only tension and no compression or bending, allowing it to span large distances economically. Tensile membrane roofs are commonly used in sports facilities, warehouses and exhibition halls.
High‑quality membranes include PVC‑coated polyester with a design life of 15–20 years, PTFE‑coated glass cloth with more than 30 years of life, and Gore Tenara (weldable PTFE) for flexible, durable retractable canopies. ETFE films can also be used, either as single‑layer sheets or inflated cushions for insulation and aesthetic effects.
Yes. While basic fabric structures may degrade over time, modern membranes like PTFE‑coated glass cloth and Gore Tenara are chemically inert, moisture‑resistant and have design lives of 30 years or more. Our custom structures use these high‑performance materials and incorporate appropriate coatings to resist UV exposure and reduce maintenance. Regular inspections and cleaning will further extend service life.
Tensile buildings offer good thermal insulation and can reduce energy consumption for heating and cooling. Their translucent membranes allow natural daylight to filter through, decreasing the need for artificial lighting. Additionally, the short construction periods reduce construction waste and environmental impact.
Absolutely. Fabric architecture provides a wide range of dynamic shapes and three‑dimensional options. Our design team can tailor the form, colour, translucency and printed graphics to meet your aesthetic and functional requirements. Whether you need a conical shade, an arched walkway, or a complex wave form, we create bespoke solutions.
These structures are ideal for stadiums, arenas, exhibition halls, warehouses, transportation hubs, retail centres, car parks, playgrounds and public parks. They are also popular as entrance canopies, walkway covers and shade structures for resorts and event venues.
High‑performance membranes like PTFE and ETFE are resistant to moisture, micro‑organisms and UV radiation. They offer good self‑cleaning properties and retain their strength and translucency over decades. Proper tensioning and drainage design prevent water pooling and ensure resilience against wind and snow loads. Fire‑resistant coatings can also be applied where required.
Unlike conventional structures that rely on heavy materials and compression members, tensile membranes use tension to create structural strength, reducing material usage and enabling lightweight, economical construction. They can be installed quickly and provide large column‑free spaces, resulting in cost and time savings. Furthermore, their aesthetic appeal and ability to create luminous, airy spaces set them apart from traditional roofing systems.
By combining innovative fabric membranes, precisely engineered tension systems, and tailored aesthetics, our custom tensile structures deliver lightweight, durable and visually stunning solutions. Whether you need to cover a stadium, shade a playground or create an iconic entrance canopy, we can design and build a bespoke membrane system that meets your budget and enhances your environment.
