The Pros and Cons of Triple Glazed Windows

Triple glazed windows are becoming very popular. If you are considering getting triple glazed windows for your home, here are the pros and cons to help you make your decision.

The glazing actually refers to how many panes of glass are in the frame. Double glazed windows have two panes of glass with a space in between. This space contains gas that helps to insulate the window. Triple glazed windows have three panes of glass, and two spaces in between the panes. Of course, both of these are filled with insulating gas which is what helps them to be so energy efficient.


Triple glazed windows can have up to a 30% higher energy rating than double glazed windows, making them the most energy efficient windows on the market. They are also more durable and safer than double glazed windows. They have a lower u value and less issues with condensation. They are also better for reducing noise from outside than double glazed windows. If you are looking for maximum energy efficiency and safety, triple glazed windows are certainly the way to go.


Unfortunately there are a few cons to having triple pane windows as well. The main con associated with them is that they are generally more expensive. However, you will save money in the long term because they last longer and they are more energy efficient. They are also heavier than double glazed windows, but this also helps them to be more durable. Since it isn’t something that you notice once the windows are installed, it really can’t be considered much of a con.
