| • R-value - Resistance a material has to heat flow. The higher the R-value, the greater the resistance. • Radiation - Wave energy transmitted directly from one object to another through the atmosphere or through transparent or translucent materials. The energy radiated is either transmitted, absorbed, reflected or a combination of all three. • Rail - The horizontal sections of the sash. • Raised Exterior - An angled extension from the frame that adds an aesthetically pleasing dimension to the exterior of the window. • Relative Humidity Condensation Point - The relative humidity level at which visible water vapor or other liquid vapor begins to form on the surface of the sash or frame, based on an inside temperature of 70E F and an outside temperature of 0E F. The higher the percentage, the more moisture the air can hold before condensation will occur. • Rollformed Screen Frame - A method of fabrication in which a flat (usually metal) material is placed on a machine where the material is formed into shape using differently shaped rollers and pressure. • Sash - The part of the window which contains the glass. • Sash Alignment System - An exclusive hinge-type system used on hung windows. This system attaches the sash to the balance, creating perfect alignment between the sash and frame, while allowing the sash to tilt inward for cleaning. • Secure Nest™ Cam Lock - The mechanisms, which draw the sash together into a tight formation with an interlocking cam inside a recessed keeper. • Secure Seal™ meeting rail - An overlapping/interlocking meeting rail. • Shading Coefficient - The ratio of solar heat that is transferred through a glazing material relative to the solar heat transferred through 1/8" clear glass. The lower the number the more efficient the window is at reducing solar heat gain. • Sill - The horizontal, bottom section of the main frame. • Sill Extender - An extrusion that is attached to the bottom of the window to cover the gap between the sill and the rough opening. • Simonton Sill® - An exclusive triple-stepped, sloped sill design. • Single Hung - A window in which one sash slides vertically and the other sash is fixed. • Single-strength Glass - Glass with a thickness of approximately 3/32". • Slider Window - A window in which the sash move horizontally. Sliders are available in a 2- or 3-lite configuration, with the 3-lite having operable end vents. • Sloped sill - The sill of the window that has a downward slope to the outside. This sill has sufficient degree of slope to aid in water runoff. • Solar Heat Gain - The percentage of heat gained from both direct sunlight and absorbed heat. The smaller the number, the greater the ability to reduce solar heat gain. • Spacer - Material placed between two or more pieces of glass in order to maintain a uniform width between the glass, and prevent sealant distortion. • Stepped Sill - An exclusive triple-stepped, sloped sill design. • Stile - The vertical sections of the sash. • Stucco Fin - An extrusion used in stucco home installations that is attached to the main frame to create a smooth, finished look for both the window and the stucco. • Super Sensor Glass™ - A superior energy efficient glass package that offers 1" double strength glass, a solid silicone foam spacer and an optimum ?" airspace filled with Argon gas. • Super Spacer® - A solid silicone foam spacer covered with Mylar. It is sealed to the edge of the glass and then sealed with butyl for greater energy efficiency. |
