If your home feels cold and drafty – even when the heat is running – your windows may be the problem. Drafty windows are one of the most common issues Colorado homeowners face, especially during Denver’s long winters and unpredictable weather swings. When windows fail, they allow cold air to seep in and warm air to escape, forcing your heating system to work overtime and driving up your energy bills.
At New Windows for America, Denver’s most trusted window experts, we help homeowners eliminate drafts, improve comfort, and save money by upgrading to modern, energy-efficient windows designed specifically for Colorado’s climate.
Why Drafty Windows Are So Common in Colorado Homes
Colorado experiences extreme temperature shifts, high winds, intense sun exposure, and sudden snowstorms. Over time, older or builder-grade windows struggle to keep up with these conditions. Common causes of drafty windows include:
- Single-pane or outdated double-pane glass
- Worn seals and failed insulating glass units
- Poor installation or aging frames
- Lack of proper insulation around the window opening
If you notice cold spots near your windows, condensation, rattling glass on windy days, or rising utility bills, it’s a strong sign your windows are no longer energy efficient.
Energy-Efficient Window Upgrades: What Really Works in Colorado
Homeowners searching for the best energy-efficient windows in Colorado often ask what technologies actually make a difference. Here’s what you should know.
Double-Pane vs. Triple-Pane Windows
Modern energy-efficient windows use multiple panes of glass to create insulating barriers.
- Double-pane windows are a solid upgrade from single-pane and work well for many Denver homes.
- Triple-pane windows offer maximum insulation, dramatically reducing drafts and heat loss—ideal for Colorado’s cold winters and windy conditions.
Both options are a massive improvement over older windows, but triple-pane windows provide superior comfort and energy savings for homeowners who want the best performance.
Low-E Coatings: Keeping Heat Where You Want It
Low-E (low emissivity) coatings are microscopically thin layers applied to window glass. They reflect heat rather than absorbing it.
In Colorado:
- During winter, Low-E coatings help keep heat inside your home
- During summer, they block excessive solar heat, keeping rooms cooler
This balance is critical in a climate with intense sunshine and cold temperatures—making Low-E glass a must-have feature for energy-efficient windows in Denver.
Argon or Krypton Gas Fills
The space between window panes is filled with insulating gas, most commonly argon. These gases are denser than air, slowing heat transfer and reducing drafts.
Gas-filled windows:
- Improve insulation
- Reduce temperature fluctuations near windows
- Increase overall comfort year-round
This is one of the simplest yet most effective technologies for reducing energy loss in Colorado homes.
Understanding U-Factor and SHGC for Colorado Windows
Many homeowners ask: “What U-factor and SHGC should windows have in Colorado?”
Here’s the quick breakdown:
- U-Factor measures how well a window insulates.
- Lower numbers = better insulation
- For Colorado, a U-factor of 0.30 or lower is ideal
- SHGC (Solar Heat Gain Coefficient) measures how much solar heat enters your home.
- Moderate SHGC values are best in Colorado
- This allows beneficial winter sun while limiting summer heat gain
At New Windows for America, we help homeowners choose the perfect balance based on their home’s orientation, elevation, and personal comfort goals.
Can Energy-Efficient Windows Lower Utility Bills?
Yes – dramatically. Drafty windows are one of the biggest sources of energy loss in a home. By upgrading to energy-efficient windows, homeowners can:
- Reduce heating and cooling costs
- Eliminate cold drafts and hot spots
- Improve indoor comfort in every season
- Put less strain on HVAC systems
Many homeowners also ask about energy-efficient window rebates in Colorado. Depending on the year and available programs, rebates or tax incentives may be available for qualifying ENERGY STAR® windows. Our team stays up to date and helps guide homeowners through potential savings opportunities.
