Energy Efficient Windows – Costs & Savings

Replacement Window and Doors in Denver 

Energy-efficient windows are an essential consideration for both new and existing homes

Are you already feeling the heat? The windows in your home can greatly impact the heat that enters or escapes. Understanding the significant consequences of having subpar, builder-grade windows installed is important. The beauty of having new energy-efficient windows adequately selected and installed is that they can significantly help improve window performance in your home and help minimize unnecessary heating, cooling, and lighting costs.

Benefits of Having Energy-Efficient Windows


Improves Energy and Cost Savings

When the glass on windows is not very efficient, it allows excessive radiant heat and harmful UV and infrared rays to enter. This results in unwanted heat gain during summer and heat loss during winter, and forces you to spend extra money on constantly running air conditioning, swamp cooler, attic fan, or regular fans, which increases electricity consumption.

With our energy efficient windows, glass technology makes it possible for you to have super energy-efficient windows with low-E coatings.  This reduces the higher solar heat gain, without compromising the design, view, or the amount of daylight that comes in.

Reasons for Home Energy Loss

These windows have special coatings that protect your home's fabrics, floors, and art from sun damage, saving you money on replacements.

Reduces Your Carbon Footprint

By installing our energy-efficient windows, you can reduce the amount of power you consume, which in turn helps reduce greenhouse gas emissions. This is because the energy you save would have been used to create greenhouse gases. Conserving energy in this way is an excellent method to reduce your overall carbon footprint and contribute to a greener planet.

Enhances Your Home’s Thermal Equilibrium

Energy-efficient windows are designed with Low E coatings on the glass to provide excellent thermal resistance. This feature ensures that your home is not overheated by direct sunlight, allowing you to maintain a comfortable temperature indoors, even on scorching days in Colorado. So, you can stay cool and relaxed when the weather gets hot.

Low E 366 Glass

A study conducted in Roseville, California, showed that using Cardinal's LoĒ² glass can make a significant difference in keeping homes cool and saving energy in the hot and dry Southwest. The study compared two identical houses, with one equipped with clear double pane and the other using LoĒ² glass. The results indicated that the house equipped with LoĒ² glass showed a 25% reduction in cooling energy and 10% savings in heating energy. Furthermore, the air conditioning unit used in the LoĒ² glass house ran 1/3 fewer hours compared to the one used in the test house using regular low-e glass.


Improved Lighting and View

New fiberglass windows with low-E coatings serve as the perfect window replacement solution to the traditional tinted glazing or shades on your windows to reduce solar radiation. These windows protect your home from unwanted heat without obstructing your views or the amount of daylight that penetrates your home interiors.

Costs for Energy-Efficient Options

Replacement windows with Low E coatings have now become a standard feature. On average, the cost of having these windows installed cannot be considered expensive, particularly when you consider the enormous costs incurred when you don’t. This is one of the features that will increase the value of your window.

Caution: U-Factor Rating for Windows 

You do not want to get caught up in a situation where you have purchased windows according to the U-factor of the glass and have ignored the material of the window frame itself.  It is crucial to consider that the U-factor of energy-efficient windows may only pertain to the efficiency of the glass, not the entire window. Often, the frames do not have the same level of energy efficiency as the glass. This is why we recommend using fiberglass for the window frame to ensure optimal energy efficiency.
