Most Popular Types of Energy-Efficient Windows in Denver, CO

Energy-efficient windows keep your home warm in the winter and cool in the summer. That saves your air conditioner or furnace from working overtime to keep your house comfortable. Saving energy also means saving money. While energy-efficient windows might have a higher installation cost, their lifetime cost makes up for it. 


What Makes a Window Energy-Efficient? 

Double- or triple-glazed window panes add layers of insulation to your home. Double-glazed windows have two layers of glass per pane, while triple-glazed have three layers. The space between the glass layers is filled with air or, more often, argon. Argon is better at blocking heat and sound, and it doesn’t contain moisture, which can create condensation between the glass.  

Energy-efficient windows usually include a low-E film that blocks UV rays and helps prevent external heat and cold from entering the house.  

Are Energy-Efficient Windows Cost-Effective? 

Despite the high installation costs, you can still save money at this part of the process. Triple-paned windows are the most expensive and typically use krypton gas, rather than argon. Krypton is more expensive, but it’s a better fit for the smaller spaces between the three panes.   

It’s also a better insulator, so your energy savings over windows’ life will be more significant, especially if windows are treated with a low-E coating. Triple-paned windows filled with krypton gas and coated with low-E films can decrease energy bills by up to 50%.  

Double-paned windows filled with argon are more expensive than double-paned windows filled with air. They’re also more energy-efficient. Using a low-E film on double-paned argon-filled windows further increases their efficiency.  

Gas-filled windows can leak if they’re not sealed properly. Krypton and argon are both non-toxic, so the leaking gas won’t hurt you. However, the gap in your windows will be filled with air instead, exposing them to condensation and resulting in lower energy-efficiency for your home.  

The Frame is Key 

Using energy-efficient windows will have little to no impact if you don’t choose the right frame. You should choose your window frames based on the climate you live in. If you’re in a warm and sunny area with little to no rainfall, a wood frame might be the best option for you. If you live in a wet, humid area, wood will cost a fortune to maintain.  

A wood composite frame often works best, in terms of energy-efficiency and long-term maintenance. The appearance is just as attractive as wood, but it doesn’t require the maintenance that real wood does. The composite material is durable and insulating and is resistant to rot, decay, mildew, and mold.  

Vinyl frames are also durable and insulate well. Wood frames may be the best insulators, but they have significant maintenance costs. Aluminum and other metal frames are lightweight and inexpensive but are the least energy-efficient. Metal is much more efficient at conducting heat, so, in addition to transferring heat into the house, the frame itself could be hot to the touch, posing a danger to your family.  

When you’re looking for the best windows for your home, consider energy costs. Windows should keep your home safe and comfortable, so be sure you choose energy-efficient windows that save you money as they age. Get in touch with Colorado Window Source Denver today and speak with our window experts.
