The Fabric

Our exclusive tensile fabric is completely waterproof and is constructed from a woven base cloth which has high tenacity polyester threads. Throughout the manufacturing process, the fabric is coated under constant tension in both warp and weft directions giving it a high performance polymer surface layer. The exclusive technology used on the yarn, gives it true elongation resistance, so once coated, minimum movement in the finished product will occur which is a key factor in the durability of the fabric on your tensile structure.

The Keswick is supplied with white fabric as standard however, if you would like a colourful structure to match your surroundings, there are 39 additional colours to choose from which are available at an additional cost. The fabric can adapt to any required shape and size including walkways and umbrellas which makes them particularly suited to the education and leisure sectors. The flexibility of the fabric allows us to present you with an exciting range of tensile structures in whatever commercial settings you require cover for.

The Keswick Umbrella requires only periodic cleaning. To clean the structure we recommend a solution of warm water and a non-abrasive cleaner. For more information please see the maintenance schedule which is found in your After Sales pack.
