Understanding Double Glass for Windows
Double glass windows are common in new homes and when old windows are replaced. They have two panes of glass with a gap in between. This gap is filled with gas like argon or krypton, making them better insulators than regular windows.
Components and Construction
The main parts of double glass windows are:
- Two panes of glass
- A spacer that separates the panes, creating an air gap
- An insulating gas, such as argon or krypton, filling the air gap
- A low-emissivity (Low-E) coating applied to one or more of the glass surfaces to reflect heat
How Double Glazing Works
Double glass windows block heat well, saving energy. The gas and Low-E coating stop heat from passing through. This keeps the inside of your home warm or cool, as needed.
Types of Insulating Gases Used
Argon and krypton are the gases used in these windows. Argon is cheaper and used a lot in homes. Krypton is denser and better for keeping out cold, used in triple-pane windows or in very cold places.

Heat Transfer and Insulation Properties
Windows play a big role in how well a house keeps warm or cool. The U-factor and Solar Heat Gain Coefficient (SHGC) show how good a window is at keeping heat in or out. The U-factor tells us how well a window insulates. A lower U-factor means better insulation.
The SHGC shows how much sunlight can get through the window. This affects how much heat comes into the house.
- U-Factor Ratings Explained: Double-glazed windows keep more heat in than single-pane ones. This means they help lower your energy bills. You also get to enjoy a more comfortable home because you need to use your heating less.
- Solar Heat Gain Coefficient (SHGC): The SHGC of a window controls how much sunlight can enter. This affects the heat inside your home. Windows can be made to let in more or less sunlight, depending on where you live.
- Thermal Performance Metrics: Energy ratings, like the Energy Star system, help us compare windows. A higher rating, like A+, means better insulation and lower bills. This is great for saving money and keeping your home cozy.
