PVC-coated polyester fabric PVC Polyvinyl chloride This high-tenacity membrane material has been used for more than 30 years for roofing and facades as well as for temporary structures and exhibition buildings. The great variety of different types available in many different tensile strengths and colours allows a wide range of application. The high tensile strength available allow wide span membrane structures to be built. In addition to its suitability for permanent structures, the high flexibility of the fabric makes it ideal for re-tractable systems. This is a very economical membrane material that has become very popular in all types of application. There is a wide range of strengths, weaving and coating types available, from standard materials up to high quality, highly engineered membrane. The exact type of membrane will be selected to conform to the pro-ject specifications. Detailed characteristics: Life span: Life expectancy is 15 ֖ 20 years, depending on the specific project. Fire rating: The material is self-extinguishing and flame resistant according to DIN 4102 B1or other inter-national standards. An additional advantage in case of fire is the very low density, the most common mate-rials being between 0.5 and 1.5 mm thick. Material pollution: The addition of anti-adhesive PVDF (Polyvinyl di-fluoride) coatings has meant that ma-terial staining has been considerably reduced over the past 10 years, compared to the standard materials (still available) with only an acrylic coating. One major advantage of the PVDF coating is the considerable increase in cleaning intervals. Cleaning: Depending on the specific characteristics of the coating, the material is more or less dirt-resistant and the cleaning intervals vary according to the appearance required. Cleaning is carried out us-ing ecologically greenђ detergents. >

Maintenance: The material is maintenance-free. However, inspections are still recommended in order to find defects (for example damage caused by mechanical impacts of sharp objects) and to identify and re-pair such damages as early as possible. It is also recommended that the perimeter clamping system and the primary structure be regularly inspected. The inspections should normally be carried out annually. However, the specific intervals need to be as-sessed on a project-by-project basis. They can be carried out in conjunction with any cleaning, if the client requests this. Environmental...
