Architecture is a dynamic field, with technologies and materials constantly evolving. A revolution making waves in the construction world, architectural membranes are thin, flexible materials that serve as a protective layer for structures. Typically composed of materials such as polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETFE), and coated fabrics, these membrane in architectures offer the unique properties of high strength and flexibility. These lightweight, flexible and durable materials have become an integral part of modern structural design and construction.

Types of architectural membranes

PVC Membranes:

• Versatile and cost-effective.
• Commonly used to tensile fabric architectures.
• Excellent weather resistance and UV radiation resistance.

PTFE Membranes:

• Offers exceptional durability and ability to withstand extreme temperatures.
• Ideal for long-span applications.
• Known for its self-cleaning properties.

ETFE Membranes:

• Transparent, lightweight, and environmentally friendly.
• For transparent roofs and facades.
• Has excellent thermal insulation properties.

Many customers choose PVC membranes from the FLFX factory because of their excellent flexibility, tear resistance, self-cleaning, UV resistance, etc. This PVC architectural membrane material is exposed to sunlight, and the interior of the building is filled with natural diffuse light, making the indoor space brighter. The service life of the architectural membrane is more than 25 years. The strength of the material can maintain a stable mechanical structure even in typhoons and rain weather.

FLFX PVC architectural membrane is also a type of PVC tarpaulin. It mainly adopts the industry-leading knife coating process and introduces PVDF and fluoropolymer surface treatment imported from Germany. It achieves excellent weather resistance and stain resistance while effectively blocking plasticizer migration and anti-aging. Thereby greatly extending the service life of the membrane material. Mainly used in large public facilities such as stadiums, exhibition halls, shopping malls, and airports.

Types of tensile fabric architectures

Tensile fabric architecture, also called tensile membrane architecture, is a specialized construction and structural engineering technology. Lightweight yet strong architectural tensile roofs or shading structures are created primarily from materials such as PVC, PTFE or ETFE. In this construction method, the fabric is stretched taut to create a three-dimensional surface that can span large areas while remaining stable and resisting environmental forces.

Tensile fabric architectures offer architects and designers significant flexibility in shape and form. Tensioned membranes can take on a variety of shapes, including cones, domes, sails and other free-form designs. Tensile membrane architectures are lightweight compared to traditional building materials. This property makes them ideal for creating large covered spaces without the need for heavy support structures.
