Amawindi angenazimele athatha yonke imilimitha yokugcina yokubuka ngaphandle. Ukuxhumana okungenamthungo phakathi kwe-glazing negobolondo lesakhiwo kudala ukubukeka okuhlukile ngenxa yoshintsho olubushelelezi. Ngokungafani namafasitela avamile, izixazululo ze-LEAWOD zisebenzisa ifreyimu ye-thermla break aluminium.
Esikhundleni salokho, amafasitelana amakhulu aphethwe ngamaphrofayili amancane afihlwe ophahleni naphansi. Ubuhle, ukuhlelwa kwe-aluminium cishe okungabonakali kunomthelela ekwakhiweni okuncane, okubonakala kungenasisindo.
Ugqinsi lwe-aluminium ludlala indima ebalulekile ekuthuthukiseni ubuqotho besakhiwo nokuhlala isikhathi eside kwamafasitela. Ngogqinsi luka-1.8mm, i-aluminium inikeza amandla angavamile, iqinisekisa ukuthi amafasitela angakwazi ukumelana nomoya onamandla, imvula enamandla, namanye amandla angaphandle angase ahlangane nawo ezindaweni ezisogwini.
