You can configure uPVC tilt and slide patio doors to feature two, three or four panels in total. The size of the door depends on the number of panels you choose. To give you a rough idea, however, a single panel usually measures between 80 and 100 cm in width. The minimum and maximum dimensions that are technically possible are also specified in the configurator. If you would like a sliding door in a smaller or larger format, however, feel free to contact our customer service team directly, and they will find a bespoke solution to suit your needs.
