This is a modern design gauze-roller. It, just like usual rollers can be rolled into a coil. The installation of this type of gauze is done from the outside on the window frame. The gauze can be rolled into a compact cassette (the spring mechanism allows to do this easily). You can choose the colours of the frame – white and brown. This type of gauze is installed on the window and balcony doors. There are also two types of available opening variations (horizontal and vertical). At the end of summer, the warm season or at the disappearance of insects the gauze is usually rolled up until next use.
