If you are on the market for window replacement, an important topic to consider is that of window glazing. There is a common misconception that this is something people do to their windows to make them more energy efficient and while this is partly true, window glazing in actuality refers to the window glass itself when installed within the window frame. While windows come in a wide range of colours, designs, and styles, they will often come equipped with either single or dual pane sheets.

Double Pane Windows

Double panes are the standard for energy efficient windows and because of this, are often referred to as “double hung” windows. The idea behind double glazed windows is that the double glass panes, in combination with the immediate buffer zone, will provide a more effective barrier against outside temperatures as opposed to single-paned windows. Double-glazed windows are now considered the standard for both replacement windows as well as newly constructed windows. There are many advantages associated with double pane windows outside of saving you money on your energy bills. They also offer noise insulation to help block outside noise, making your home more peaceful and tranquil. Double glazed windows also minimize condensation and can even offer stronger safety.

Triple Pane Windows

To ensure your home is completely sealed up for the cold winter months, you can even choose a triple glaze that will go in between the two panes. Triple pane windows are excellent options for homeowners living in extreme northern climates. They are also great sound reducers for homes near highways or airports, however the extra pane of glass makes for a thick, heavy, and more expensive sash. However, these highly efficient windows will keep the gaps between the inner and outer glazes from allowing air inflow or outflow, although this is usually kept to a minimum due to the gases present inside.

The majority of modern windows are energy-efficient and are integrated with advanced coatings that are heat-sensitive. Homeowners have the ability to choose between a variety of window glazing options that include low-E glass, triple-pane insulated glass, double-pane insulated glass, and single-pane glass.

This will coat the glass in a clear film that is meant to block out light, which will provide you with even more energy savings.

Measuring Window Insulation

Window glazing is rated on three criteria: its ability to insulate, how much light it filters through, and its ability to block heat from the sun. By evaluating these factors, you can choose the best windows that are the most suited to your climate and even customize windows for specific rooms in your home.

A window’s ability to insulate is measured in a handful of different ways. The most common way to measure this is with the R-Value system, which is a measurement of how well materials resist energy transfer. In this system, the higher R-value translates into greater resistance and thus, higher insulation. The glazing options available to homeowners today can even create windows that have almost the same insulation value as walls!
