GLOSSARY OF WINDOW TERMS The Learning Center Casement Window A casement style window is hinged on one side and cranks out, often using a hand crank. More expensive than a sliding-type window. Cladding Is the application and process of bending custom painted aluminum to fit around the outside sills and casing. This is a feature that you should inquire about and not just assume it is part of the installation. Clear Clear windows just means that there is no Low-E coating on the glass. Low-E coatings reduce the amount of heat that can come in or get out through the window. Condensation The accumulation of water vapor or droplets as the result of warm, moist air coming in contact with a cold surface and cooling to its dew point temperature. Condensation may occur when a cold window glass or frame is exposed to humid indoor air. Low-conductivity, insulated glass and warm- edge spacers reduce condensation. Casement Window - Desiccant Conduction The transfer of heat through a solid material, such as glass or wood, through direct contact. Heat flows from a higher-temperature area to a lower-temperature one. Convection The flow of heat that occurs through a circulating gas or liquid (such as air) as warm air rises and cool air sinks. Convective heat transfer can take place in large areas (like rooms and buildings) and in small areas (like the cavity between two layers of insulated glass). Low-E insulated glass units lessen cold convection currents by maintaining warmer interior glass surface temperatures. Desiccant A drying agent that is placed inside the panes of glass in a double or triple pane window (IGU) to absorb any moisture that may get between the glass panes. < previous main menu       next > 1-877-SWING CLEAN info@energyswingwindows.com 3245 Miracle Drive Murrysville, PA 15668 724-387-2991 PA Contractor ID PA001856
