Zomatira zamagalasi ndi zomatira zimakhala ndi zinthu zosiyana kwambiri. Chifukwa chake, ndikofunikira kusiyanitsa pakati pawo mukamagwiritsa ntchito. Kugwiritsa ntchito molakwika kungayambitse mavuto aakulu. Nawa mitundu iwiri yayikulu muzochita zawo:
Mphamvu Zomatira: Glass sealant, m'malingaliro mwanga, ndi mtundu wa zosindikizira, zofanana ndi nyengo yodziwika bwino ya silikoni-resistant sealant. Chifukwa chake, mphamvu zake zomatira sizokwera kwambiri. Ntchito yake yayikulu ndikusindikiza. Kwenikweni ndi silicone sealant. Komano, zomatira zamapangidwe zimafunikira mphamvu zomatira zapamwamba kwambiri. Izi zikuphatikizapo mphamvu yopondereza, mphamvu yolimba, ndi mphamvu yakumeta ubweya. Zomata zomangika zimafunikira mphamvu yopondereza yopitilira 65 MPa, mphamvu yamphamvu yopitilira 30 MPa, komanso kumeta ubweya wambiri kuposa 18 MPa.
Moyo Wautumiki: Zomatira zambiri zamapangidwe zimapangidwira kuti zizikhala ndi moyo wofanana ndi nyumbayo. Ndiko kuti, ngati nyumba idapangidwira moyo wazaka 50, ndiye kuti zomatira zomwe zimagwiritsidwa ntchito ziyenera kukhala ndi moyo wautumiki wa zaka 50. Choncho, zomatira zomangira zimakhala ndi moyo wautali kwambiri. Mosiyana ndi izi, silicone sealant nthawi zambiri imakhala ndi zovuta monga kusenda ndi kusweka pakapita zaka zingapo. Chifukwa chake, zomatira zamapangidwe ndizopambana kwambiri kuposa silicone sealant.
