Solid balcony “unit”: door – shutters – fly screen (plisse). An ideal exit from a kitchen, a bedroom, or from a study to a terrace … by design. Also offers protection against uninvited guests. Optimum height up to 2.6 meters. Shutters with a fly screen protect you from harsh sunlight, mosquitoes in summer and serve as an additional barrier from frost, wind or hail during cold periods. Shutters with ТМ Schlegel seals serve as a second door in the most severe climate conditions.
