Yintoni ukulinganisa kwe-NFRC kwiifestile?
Ileyibhile ye-NFRC ikunceda uthelekise phakathi kweefestile ezisebenza ngamandla, iingcango, kunye ne-skylights ngokukunika ukulinganisa ukusebenza kwamandla kwiindidi ezininzi. U-Factor ulinganisa ukuba imveliso inokugcina ubushushu bungaphumi ngaphakathi kwegumbi. Okukhona lisezantsi inani, kokukhona imveliso igcina ubushushu ngaphakathi.
Ukuqinisekiswa kwe-NFRC kunika abathengi isiqinisekiso sokuba imveliso yeVinco ilinganiswe yingcali yehlabathi ephambili kwifestile, umnyango, kunye nokusebenza kwesibhakabhaka, ngaphezu kokuqinisekisa ukuthotyelwa.
Imele ntoni i-AAMA kwiifestile?
Esinye sezatifiketi ezixabisekileyo kwiifestile zinikezelwa yi-American Architectural Manufacturers Association. Kukho kwakhona isimboli sesithathu sokugqwesa kwefestile: isiqinisekiso esivela kwi-American Architectural Manufacturers Association (AAMA). Kuphela iinkampani zefestile ezithatha iSiqinisekiso se-AAMA, kwaye iVinco yenye yazo.
IiWindows ezinezatifikethi ze-AAMA zihlangabezana nemigangatho ephezulu yomgangatho kunye nokusebenza. Abavelisi befestile bathatha inkathalo eyongezelelweyo kubugcisa beefestile zabo ukuhlangabezana nemigangatho ebekwe yi-American Architectural Manufacturers Association (AAMA). I-AAMA ibeka yonke imigangatho yokusebenza kwishishini lefestile.
