Energy Efficient Windows

Colorado’s cold climate presents a particular challenge to homeowners. Too often, much of the heat generated inside the home escapes out through windows, unsealed doorways, and uninsulated areas. Before making any purchases, you can always request a free consultation from Paramount Siding and Windows in Denver, Colorado. We are happy to assist you in finding the best energy-efficient window type for cold climates and the perfect fit for your home. Call or contact us today for more information!

To create a comfortable living space in your home, you need energy, usually in the form of central heating and fireplaces. This can contribute significantly to your monthly household bills. You don’t want to see these funds going to waste – or out the window.

Unfortunately, insufficiently insulated glazing can account for 25% of an average home energy bill. To protect your bank account, investigate the NFRC ratings of products before you buy them. And don’t be afraid to shop around and compare different brands.


The best energy-efficient window type for cold climates needs to have fully sealed frames to prevent draughts. They should also be properly installed by a professional. While aluminum frames are robust and affordable, they’re not good insulators. If you live in chilly Colorado, you should choose wooden or clad frames if your budget allows. Otherwise, vinyl frames can insulate well at a more affordable cost.


One pane of glass will not be able to insulate your home as well as two or three panes of glass. Double or triple glazed windows will drastically increase the R-value of a window, which measures the capacity of a window to prevent heat transfer. The vacuum created between the panes, or the gas fill, will act as a buffer to stop heat from escaping and cold from entering your home.

Also, pay attention to the spacers used to separate the panes of glass. Warm spacers made from wood or rubber perform much better as insulators than metal spacers.


Beyond frames and glass is a range of coatings and treatments that can be applied to window glass to make it even more efficient. A Low E-Coating can be used to reflect heat back towards its source. If this transparent metallic oxide is applied to the inner surface of the outermost pane of glass, it will reduce the amount of heat that escapes from your home across the window. This especially worthwhile on large picture windows or sliding patio doors, which have more potential for heat loss.


Logically, opting for multi-paned windows in place of one large pane will increase the overall energy efficiency of the window, however, many clients prefer large windowpanes for aesthetic purposes.

Finally, installing storm windows on the inside or outside of your window glass is another method to increase overall insulation. These can serve a double purpose if your home is in a cold climate (like chilly Colorado) and an area prone to extreme weather (like hail).
