Energy Efficient Windows
Defining Energy Performance Ratings: 
- U-Factor – A measure of the rate of heat flow through a window. Heat efficient windows have better insulating properties. A lower U-Factor indicates a higher performing window that can help reduce heating and cooling costs.
- Solar Heat Gain Coefficient (SHGC) – The amount of solar radiation allowed to pass through a window. The lower the number, the less solar heat gain the window permits.
- Structural-Design Pressure (DP) – The amount of wind pressure a window will withstand when closed and locked is called Structural-Design Pressure (DP). The higher the number, the better.
- Visible Light Transmittance – Ranging from 0 – 1, visible transmittance is a measure of how much light passes through the window.
