Mazenera opanda zingwe amatenga ma millimeter omaliza akuwona kunja. Kulumikizana kosasunthika pakati pa glazing ndi chigoba cha nyumba kumapanga mawonekedwe apadera chifukwa cha kusintha kosalala. Mosiyana ndi mazenera ochiritsira, njira za LEAWOD zimagwiritsa ntchito chimango cha aluminiyamu ya thermla.
M'malo mwake, mapanelo akuluakulu amagwiridwa muzithunzi zopapatiza zobisika padenga ndi pansi. Zokongola, pafupifupi zosaoneka za aluminiyamu edging zimathandiza kuti zomangamanga zikhale zochepa, zooneka ngati zopanda kulemera.
Makulidwe a aluminiyamu ndi gawo lofunikira pakukulitsa kukhulupirika kwa mazenera komanso moyo wautali. Ndi makulidwe a 1.8mm, aluminiyumu imapereka mphamvu zapadera, kuonetsetsa kuti mazenera amatha kupirira mphepo yamphamvu, mvula yambiri, ndi mphamvu zina zakunja zomwe zingakumane nazo m'madera a m'mphepete mwa nyanja.
