FGIA Releases New Surface Temperature Assessment for Condensation Evaluation of Exterior Wall Systems

The Fenestration and Glazing Industry Alliance (FGIA) has developed a new document providing a standard procedure for the measurement of surface temperatures to be used in the condensation evaluation of exterior walls under laboratory conditions. AAMA 501.9, Surface Temperature Assessment for Condensation Evaluation of Exterior Wall Systems, an FGIA standard, is now available for purchase.“AAMA 501.9 is another optional test that can be performed in conjunction with a project specific curtain wall mock-up,” said Greg McKenna (Kawneer), Vice Chair of the Wall Mock-up Condensation Evaluation...

FGIA Releases New Document for Determining THERM Finite Element Modeling Surface Temperatures

The Fenestration and Glazing Industry Alliance (FGIA) has released a new publication addressing aspects of the finite element (FE) thermal modeling process often used to predict interior surface temperatures on fenestration including non-residential windows, terrace and patio doors, curtain wall, storefront, and entrances. AAMA 515-19, Voluntary Procedure for Determination of Fenestration Surface Temperatures by THERM Finite Element Modeling, an FGIA standard, is now available for purchase in the FGIA online store.Per AAMA 515, condensation will occur on any interior surface that falls below the dew...
