Wood & PVC | Glazing Options
We have an unlimited number of glazing options available including dual pane, triple pane, custom obscure patterns, reflective surfaces, etc. Please see chart on opposite page for our most common glazing specifications. Your sales representative can assist with any other glazing configurations to suit your desired requirements.
Solar Heat Gain Coefficient - (SHGC)
The amount of solar radiation that enters a building as heat. The
lower the number, the better the glazing is at preventing solar
heat gain.
Fading Transmission
The portion of energy transmitted in a spectral region from 300 to 700 nanometers. This region includes all of the ultraviolet energy and most of the visible spectrum, and will give the best representation of relative fading rates. The lower the number, the better the glass is for reducing fading potential of carpets and interior furnishings.
U-Factor
This represents the heat flow rate through a window expressed in BTU / hr / ft2 / °F, using winter weather conditions of 0°F outside and 70°F inside. The smaller the number, the better the window system is at reducing heat loss.
R-Value
Designates window resistance to heat flow. The higher the R-Value, the more efficient the window is in reducing winter heating costs. (This number is the inverse of U-Value.)
