Zenera la udzudzu logudubuzika izi silina kanthu koma njira yofanana ndi makina otsekera otsekera.Mapanelo amphamvu amakhomedwa kuti agwire mauna kumanzere ndi kumanja kwa ukonde wazenera.Chitoliro chozungulira chidzadulidwa kukula kwawindo lawindo ndipo mauna adzakulungidwa mmenemo ndikukhazikika molimba ndi machitidwe a masika ndipo pamapeto pake adzalowetsedwa mu gulu lozungulira la alloy.Izi zidzakhazikitsidwa ngati gulu lapamwamba la mazenera.Mbale idzamangidwa kumapeto akunja kwa mauna ndipo imakhala ndi dzenje lapakati pomwe ulusi umamangidwa kuti ukoke ndikukankhira mauna kuchokera pamwamba mpaka pansi.Phifer Quality Fibre-Glass ndizomwe zingagwiritsidwe ntchito pa izi. kapangidwe ka roller-shutter.Chitsanzochi chikhoza kukhazikitsidwa pawindo lamatabwa komanso pawindo la Aluminium.

The retractable Aluminium two track sliding systems ndi zitseko za makaseti awiri ndi makonde.Timagwiritsa ntchito makina amagudumu akumunsi kuti azigwira bwino ntchito pazitseko ndi mazenera.

Kuwoneka kowoneka bwino kolimba kwambiri pakumanga kuphatikiza kapangidwe kake kumapangitsa makina athu otsetsereka kukhala chinthu chodabwitsa kwambiri pamawindo, zitseko, makonde.amene amakhala ndi mipata yotakata kuti kuwala kwadzuwa ndi mpweya wabwino zidutse koma zokhala ndi mauna oyandikana kwambiri kuti tizilombo tiwateteze.
