Textile architecture involves flexible membranes that offer unlimited design possibilities, natural interior lighting and attractive roof surfaces. Today, both designers and contractors are convinced of the advantages of textile architecture and this solution is becoming more and more established in the construction world for multiple applications like transport, sporting and commercial infrastructures, storage, buildings, etc. Many reasons are acceptable to using a textile structure in building construction, which are as follows: The fabric structure is very light weight; Less structural support.; Low cost for construction; Large obstruction free spans; Damage can be repaired very easily; Freedom to architects to design various shapes and appearances; Recyclable. Modern - day quality synthetic materials in the form of either semi finished or finished building materials have convincing structural properties. To get high performance fabrics with good strength, hydrophobicity (water repellent), rot and fungi resistances that are essential properties of fabrics to be used that are essential properties of fabrics to be used as building construction, mainly synthetics fabrics are developed. So, the polymer coated synthetic fabric is highly appreciated in the architecture and construction textile world. As a result coated fabric is now widely used as the envelope of large building construction such as airports, stadium, sports hall, exhibitions and display hall, and storage bases for industrial and military supplies. The fabrics resist extremes of sunlight, temperature, biological attack, wind, rain and snow. Textile membranes are modern composites, most of which consist of highly stable glass or polyester fibres coated with synthetic PVC or PTFE materials. Textile construction techniques are successful because they convey an impression of elegance and weightlessness. These characteristics, coupled with efficient energy and cost savings, have helped this type of architecture to break-through in very different areas. Textile structures enable solutions tailored to all needs and the results are economic and energy saving structures. Prefabricated means that construction times are extremely short and guarantee that production plants or ware houses facilities are ready for use very rapidly. The translucent textiles are suitable for use in different applications and ensure a pleasant working atmosphere. And double - coated, insulated structures help to save energy. Single ply and multiply materials are used in the roofing market to protect building. In traditional build up roofing, alternating piles of felts, fabrics or mats are assembled in place and bonded together with layer of bituminous products such as asphalt or coal tar. Single ply roofing is made of single layer, water tight, weatherable membrane and sealed at the seams and edges. There are three types of single ply membranes: elastomers of thermoplastics and modified butimens.
