What is Double and Triple Glazed Doorglass?

When selecting doorglass and windows, your builder or contractor will sometimes use technical terms that may be unfamiliar to you. Understanding the terminology is key to being aware of the benefits or potential downfalls of your products. 

'Double glazed' and 'triple glazed' are two terms used to describe glass products like decorative glass, but people outside of the building industry are often confused by them. What does double or triple glazed glass mean, and which is a better option for your home remodel or build? We're here to help you understand these terms and their differences. 

What is Glazing?

Glazing refers to the glass that goes inside of a window. Windows can be made out of a single sheet of glass (referred to as 'single pane') or be made of multiple layers - or panes - of glass. These arrangements with multiple layers are called 'double glazed' for two panes or 'triple glazed' for three panes. 

While the verb 'glazing' can also refer to the installation of windows, when you see the full phrase 'double glazed glass' or 'triple glazed glass' it is referencing the pane count of a window or doorglass. 

Double Glazed Doorglass

Double glazed doorglass or windows have two panes of glass in the same frame. There is an air pocket in between the two panes to increase the energy efficiency and insulative effect of the glass. Single pane windows are the least efficient of all options, as cool air and heat can pass easily through the glass. 

Double glazed doorglass offers an additional buffer against heat transfer, helping keep your home cooler in the summer and warmer in the winter. While it is more expensive than single pane doorglass, it is still somewhat lightweight when lifted and installed. 

Triple Glazed Doorglass

As the name suggests, triple glazed doorglass and windows have a third pane of glass added into the frame. This provides another layer of heat protection and energy efficiency. They are ideal for homes located in more extreme climate regions or green homes. Because of their increased benefits and materials, they do tend to be more expensive than a single or double glazed option. 

Triple glazed doorglass is often used for decorative patterns and designs. The more delicate pane of glass with the design is encased by two panes of clear glass in order to avoid damage to the design and reduce the risk of moisture getting trapped in the air pocket. 

Double vs. Triple: Which is Better?

When it comes to deciding which option is better for your project, there are a few points to consider.

Double glazed doorglass is typically less expensive than triple glazed, and it is usually lighter in weight. That can make installation easier, and the frame material doesn't need to be as heavy-duty to support the additional pane found in triple glazed doorglass. However, they are not as energy efficient and cannot support many of the beautiful patterns of decorative doorglass. 

Triple glazed doorglass is stronger and more durable than double glazed doorglass. Because of the extra insulation of the third layer, they reduce noise transfer from the outdoors into your home. Three panes means less risk of condensation, better filtration of UV rays, and more thermal insulation.
