Below are the designs of our three standard sizes for your kitchen back wall. The SoWhat-Flex material is easy to make exactly to size yourself. If you have overhead cupboards and you still want to cover the space near the extractor, choose the 70 cm height. You can incorporate the material behind the kitchen cabinets or make cut-outs. To do this, use a sharp paring knife and a good metal cutting ruler. If you choose a custom size, we will mail you a design adapted to your size for approval.
