1.0 would mean all of the light was getting through and 0 would mean none of it was getting through. Our doors feature outstanding vinyl construction, nylon wheel rollers in galvanized steel housings, aluminum rail guide system for rollers. Visible Light Transmittance: measures how much of the visible light is entering the building through the glass. It represents the heat gain through 3mm clear glass. This is expressed as a dimensionless number between 0 and 1. The same radiant principle that makes a double-pane window better than a.

Solar Heat Gain Coefficient: the amount of solar radiation which enters the house through radiation. Learn how heat-reflecting glass for windows and sturdy steel for doors can up. One wrong move and you can damage the insulation functions of the glass. The higher the number the better the glass. Double pane glass is designed to work on insulation. R-Value: the amount of heat retained by the window. The lower the number the better the glass. U Value: the total heat transfer out of a window (Btu/hr-sq ft-F or W/sq m- C). All C.O.G U- and R-values are based on ASHREA Winter Conditions. Framing, cladding, frame type and other items will affect the overall thermal values of a complete window. All Heights in 3 (76) increments from 6’ (1830) to 20’ (6096), except Athena and Pinnacle which are 1. (centre of glass) ratings are based on Vision v4.0 simulations.
