Frame mosquito - nets are fixed directly to the window frame. They are made of aluminium frame covered with a net. The mounting is done by means of hooks. While placing an order specify the measurements of the width L and height H together with the thickness of the window frame G (correct type of a hook).   Frames of sizes above 100 cm width or height have in addition a supporting element placed in the middle part of the frame, along the shorter side. Mosquito - nets are available in white. It is recommended that the mosquito - net height H was larger than the height of the window frame by 5 cm, and its width L by 2 cm. The final sizes should be specified by means of taking the measurements.
