Glazing basically refers to the glass or the panes of a window. A double glazed or double paned window is one that is set in a frame with two panes of glass. There is a gap between the two layers of glass that is either a pocket of air or filled with an intervening gas.

The two panes of glass are separated by a spacer bar, which keeps them a set distance apart. The spacer bar is filled with either an inert gas that is safe and non-reactive or air. The gases used to fill the gap between the two panes are usually argon, krypton, or xenon.

Argon is the most used gas between windowpanes and is affordable. Krypton is a gas that works best in thinner spaces, which is why it is more commonly used in triple glazed windows. Xenon is the most innovative insulating gas used for windows. It is also the most expensive of all and is not as popularly seen in residences as the other two.

The gap between the two panes of glass acts as an insulator, reducing heat loss and preventing cold air from entering your home. The insulating properties of double glazing keep your home warmer in the winter and cooler in the summer.

R-values are a measure of the thermal resistance of a given material. In simple terms, R-values measure a material’s resistance to energy transfer. You can use R-values to choose the windows with the right thermal resistance. The higher the R-values of a window, the higher the insulating value of a window.

Windows with just air pockets in between the two panes usually have lower R-values compared to those filled with insulating gases such as argon. The R-values of double glazed windows with air pockets usually carry R-values between 2 and 3. Double glazed windows with argon gas, on the other hand, carry slightly higher R-values, between 3 and 5.

Some manufacturers offer double glazed windows with an extra layering of a special low-E (low emissivity) insulating film. This low-E coating reflects the UV rays, protecting the interior of your home. The coating bumps up the R-value of a window, making it more energy efficient.

Triple glazing is like double glazing but with an additional pane of glass. Triple glazing is more expensive than double glazing but offers even better insulation and noise reduction. The extra pane of glass and the wider gap between the glass panes help reduce heat loss and noise transmission even more.

Secondary glazing involves adding a second pane of glass to the inside of an existing window. This can be a cost-effective solution for homeowners who want to improve their windows’ energy efficiency and noise insulation without replacing them entirely. However, secondary glazing is less effective than double or triple glazing and may only be suitable for some types of windows.

There are several styles of double glazed windows to choose from, each with unique features and benefits. Take a closer look at some of the most popular double glazed window styles below.

Casement windows are one of the most famous styles of double glazed windows. They are hinged on one side and open outwards, providing excellent ventilation and easy access for cleaning.

Single-hung windows feature a single sash that slides upwards from the bottom, while the top sash remains stationary. Double-hung windows feature two vertically sliding sashes within a single frame. Both the top and bottom sash can be opened independently of each other. This allows greater control over the amount of ventilation and airflow in a room. Both these windows can be customized to suit your home’s interior.

Sliding windows feature sashes that slide horizontally within the frame instead of vertically, like in single-hung or double-hung windows. They are easy to use with a simple sliding mechanism allows for easy operation. It is a great option for hard-to-reach areas or for spaces behind furniture or around other obstacles.
