Fabric Membranes

What Are Fabric Membrane Structures?

General Description

  • Series of Patterned Panel welded together and tensioned to form a taut skin.
  • Fabric Membranes are formed in double curvature for rigidity against wind.
  • Free edges have a scalloped shape with a cable.
  • Edges can also be clamped rigidly to the building structure.

Types of Fabric

  • External structures use PVC / Polyester fabric with UV resistant top coatings.
  • Translucent fabric provides big energy savings on lighting.
  • New generation shade cloth can now be used for economical fabric membrane structures.
  • Internal structures can be made in a wide variety of fabrics and surface finishes.

Supporting Structure

  • Great diversity of forms and materials are possible.
  • Painted or galvanized steel is the most economical material.
  • Timber, stainless steel, aluminium and plastic composites have also been used.

Durability

  • Stainless steel fittings manufactured by us in South Africa are durable, elegant and cost effective.
  • UV resistant coatings give a life expectancy of 15-20 years for PVC / Polyester.
  • Shade cloth, with PTFE thread, can now be expected to last more than ten years.
