PVC-coated architectural fabric
It also exhibits high tensile strength and good flexural stability. The base textile is predominantly composed of the polymer polyethylene terephthalate, also known as PET (internationally PES). The PVC membrane can be treated with a wide range of additional coatings that extend its durability. For example, the Low-wick coating is used to reduce capillary action, improving moisture resistance and dirt adherence. Also in this vein are anti-adhesion coatings, such as acrylic or PVDF, which prevent the leaching of plasticizers or UV stabilizers from the PVC membrane, while sealing the surface so that less dirt adheres and a self-cleaning effect is achieved. PVC-PES membranes are classified in fire performance according to DIN 4102-1 as B1 (hard to ignite), and in the event of fire they emit little smoke and produce no flaming droplets (Euroclass: B-s2-d0).
Application of PVC fabrics
Application of PVC fabrics in textile architecture PVC–polyester fabric finds broad use in textile architecture and can be employed for temporary or transformable structures as well as for permanent membrane structures of various sizes. A wide range of standard colors, especially for thinner fabrics, broadens the market applicability of these fabrics in construction. Large quantities can also be ordered in any RAL color.
3dtex GmbH has implemented numerous projects with PVC-coated fabrics and draws on extensive experience. An example of textile coverings with PVC–polyester is the 1200 m² temporary grandstand roof for the Film Nights on the Elbe River, completed in 2019. This project demonstrates the conductivity of the PVC membrane during annual spring installations when the fabric is tensioned onto the wooden supports. Another project realized with PVC membranes is the membrane roof for the high-ropes course at Tankumsee, completed in 2021. For the permanent high-point structure with a diameter of 24 m and a spatial area of over 850 m², a Type III PVC fabric was used. Other projects include Lehnin Monastery and the sculpture enclosure for Schloss Seehof. The upcoming Stadtschirm product from 3dtex GmbH also envisions a high-quality PVC-coated fabric.
