Iifestile ezingenasikhelo zithatha yonke imilimitha yokugqibela yeembono ngaphandle. Udibaniso olungenamthungo phakathi kokukhenkceza kunye neqokobhe lesakhiwo lwenza inkangeleko eyodwa ebonga kwiinguqu ezigudileyo. Ngokungafaniyo neefestile eziqhelekileyo, izisombululo ze-LEAWOD zisebenzisa isakhelo se-aluminium ye-thermla.
Endaweni yoko, iipaneli ezinkulu zigcinwe kwiiprofayili ezimxinwa ezifihlwe kwisilingi kunye nomgangatho. Ubukhazikhazi, obuphantse bungabonakali i-aluminium edging inegalelo kubuncinci, obubonakala bungenabunzima boyilo.
Ubukhulu be-aluminiyam indima ebalulekileyo ekwandiseni imfezeko yesakhiwo kunye nobude obude beefestile. Ngobunzima be-1.8mm, i-aluminium inika amandla akhethekileyo, iqinisekisa ukuba iifestile ziyakwazi ukumelana nomoya onamandla, imvula enkulu, kunye neminye imikhosi yangaphandle enokuthi idibane nayo kwimimandla yonxweme.
