Triple Pane Windows


We are America’s Triple Pane Company

Triple Pane Replacement Windows from Window Depot USA are the epitome of energy efficiency, sound reduction, and condensation resistance. These high-performance windows are made with three panes of glass rather than just two for maximum benefit. Our Triple Pane Replacement Windows utilize industry-leading technology and are carefully manufactured so you can enjoy the many advantages of this amazing product


To understand the benefits of Triple Pane, we must first understand the INSULATED GLASS UNIT.

Insulated Glass Units secure two or three panes of glass together into an airtight unit, utilizing SPACERS to hold the panes apart and seal them together at the same time.

The other elements of an IG unit include Low-E coatings on the surfaces of the glass (to block certain IR and UV rays), and various INERT GASES (which are better insulators than air) used to fill the inside of the unit.

Collectively, this combination of glass panes, Low-E coatings, gas fills, and spacers make up the Insulated Glass Unit. An “IG” is also sometimes referred to as a “glass package”.

The IG unit in a window is the equivalent to the engine in a car. There are engines of different sizes, different horsepower, and different efficiencies. We all know that your engine can make ALL the difference in how your car runs, performs and lasts.

The right IG is critical to the performance, energy-efficiency, and comfort that your new windows will provide.

 “IG” (Glass Package) = Performance Engine of your Windows


In all of the windows that Window Depot USA sells…the glass has at least TWO panes. Putting two panes of glass inside of one window is referred to as ‘dual pane’, and is sometimes called ‘thermal-pane’.

These two panes of glass provide an extra barrier to heat loss (or gain) during the heating and cooling months of the year. The two panes of glass, plus the airspace between…is what allows for improved insulation.

Then when Low E coatings and specialized gas fills like Argon are incorporated…we have what we call an Insulated Glass Unit.  This is why we say that the IG is essentially the engine of the window.


As amazing as dual pane windows are, there is a ‘next level’ energy saving technology, and that is Triple Pane. As you might expect…this means that a THIRD layer of glass is incorporated into the Insulated Glass Unit.

But while this may sound simple, the effects are drastic!


Our Triple Pane windows can increase the U Factor of dual pane, clear glass windows by up to 52%. This improvement comes from a combination of the extra pane of glass, multiple cavities that contain insulating ‘blankets’ of Argon gas, and additional glass surfaces on which to apply our Low E coating technology.

Whether you live in a climate that demands more heating, or cooling of your home…the key to our Triple Pane insulating power is stopping heat flow.

In heating climates, triple pane windows keep more of your warmth and energy IN. In cooling climates, triple pane windows keep more of the radiant heat and temperatures OUT.


Condensation Resistance Factor (CRF) is a measurement used to quantify a window’s ability to resist condensation from forming. Whenever condensation is present, the first thing to look for is the atmospheric conditions…or more simply put, is your home encouraging condensation. This can come from high humidity levels and/or lack of sufficient air-flow in the home…and is magnified by windows that do not provide good insulation.

The reason why insufficient windows promote condensation is that the surface of the glass gets cooler as heat escapes.

Highly insulating windows keep the temperature on the surface of the glass warmer, and thus more resistance to condensing the moisture-rich air in the atmosphere of your home.

Our triple pane windows enhance condensation resistance of normal clear glass windows up to 49%, and can even improve normal dual pane Low E windows by over 20%.

There are many reasons to promote good cond ensation resistance. Excess moisture can lead to rotted window sills, and even mold and mildew promotion.

Triple Pane windows offer the highest CRF’s available.


Another great feature of triple pane windows is their ability to block out more the NOISE from the outside world.

The additional pane of glass, plus the extra airspace created in the Insulated Glass Unit provide additional barriers to sound transmission.

Peace and quiet can be priceless!
