The Components of an Energy-Efficient Window
No matter how beautiful it looks, glass is a fragile material that could easily break when enough pressure is applied, such as from impact or even harsh weather. Plus, glass is naturally conductive, allowing heat to pass through either side—making large, unprotected windows a nightmare when trying to cut back on energy consumption.
Energy-efficient windows are important. But what makes an energy-efficient window that way? Here are some metrics that measure its overall energy performance:
This quality measures how much heat the glass prevents from escaping. The lower the U-Value is, the better. The U-Value serves as an insulation device from both outside and inside temperature. Heat loss is the leading cause of energy drain, especially in winter and nighttime.
Solar Heat Gain Coefficient
The SHGC measures how well the replacement windows block or prevent heat from sunlight entering the room. Specifically, it describes how well the glass filters solar radiation, represented by a number between 0 and 1. The lower this figure is, the better.
Visible transmittance measures how much visible light comes through the window. The better this figure, the “clearer” the glass looks. This factor is important for daylighting purposes.
Condensation Resistance Factor
The CRF is a number from 30 to 80, which measures how much the replacement windows can resist condensation. The higher the number is, the better.
Experts said that the lower the air leakage, the less air will pass through. Energy efficiency is actually measured by how energy escapes the interior through your windows.
