Fabric sample swatches:
The Nova series is a group of external roller screen materials, available in light colours (white, ecru), greys (light and darker) and black. They are also resistant to weather elements such as strong wind or rain, thanks to the specialised materials used in their production.
The Serge group is made from a special material combining glass fibres and PVC plastic. The colour palette mostly consists of greys and browns, with occasional accents of red, green, and yellow. The material of the blinds partially allows sunlight to pass through.
