Okokuqala, Iphepha elingenanto kunye nezinto zefilimu zahlukile, imbonakalo nayo yahlukile.

1*Ixesha elihle kwaye elide elisebenzayo:
Ifilimu ngumyinge weminyaka emibini utshintsho, umsebenzi, ixesha kunye nemali.
I-Hollow sheet ingasetyenziselwa iminyaka engaphezu kweshumi, intle kakhulu.

2*Ukuhanjiswa kokukhanya:
Icwecwe elinomgongxo linokubonelela elubala olusebenzayo kunye neglosi yomphezulu, ukuze amandla elanga kwindawo nganye yeyunithi kwishedi yegreenhouse asetyenziswe kangangoko kunokwenzeka.

3*Ukugcina amandla:
I-conductivity ye-thermal (ixabiso le-K) iphantsi kunefilimu ye-greenhouse eqhelekileyo, ukwenzela ukuba ukulahleka kobushushu kuncitshiswe kakhulu.

4*Ukuchasana nempembelelo:
I-Polycarbonate yenye yezona mpembelelo zibalaseleyo ze-thermoplastics. Ishiti eliHollow linegama elithi "iglasi engaqhawukiyo" kunye "nentsimbi evakalayo".
Ngokwahlukileyo, i-canopy yefilimu ilula kakhulu ukuba ihlupheke umonakalo womzimba.

5*Ingangenwa lidangatye, ingatshi:
I-Polycarbonate inokumelana nomlilo okulungileyo. Ngovavanyo lweziko lokongamela izixhobo zokwakha umlilo, polycarbonate ehollow sheet ukwibakala B elinqanda ilangatye, kude nomlilo uyazicima.
Kwaye ifilimu echithwe phambi komlilo ayinakunyamezelwa, ihlabathi minyaka yonke liya kubangelwa ngumlilo owenziwe ngumntu ukuze ifilimu ikhuphe amafama ahlupheke kakhulu.

6*Ishiti eliHollow lokuziqhelanisa nobushushu.
Polycarbonate ehollow sheet in -100 degrees Celsius ayenzeki brittle ebandayo, ngo 135 degrees Celsius ayithambi, kwindawo ngqwabalala oomatshini bayo, iimpawu mechanical, njl akukho utshintsho olubalulekileyo.
