If your Colorado home’s energy bills seem higher than expected, your windows may be part of the reason. Older, drafty or inefficient windows can allow heated and cooled air to escape, requiring your HVAC system to work harder to maintain a comfortable indoor temperature.
Replacing outdated windows with energy-efficient replacement windows can help reduce unwanted heat transfer and improve indoor comfort. While the amount a homeowner may save depends on several factors, upgrading inefficient windows can be an important consideration for improving a home’s energy efficiency.
How Can Windows Affect Energy Bills?
Windows are an important part of your home’s exterior envelope, which means they can affect how easily heat moves between your home and the outdoors. During Colorado winters, inefficient windows can allow warm indoor air to escape while cold outdoor air enters. In the summer, heat from the sun can enter through the glass, potentially increasing the demand on your air conditioning system.
Drafts can make the problem even more noticeable. If you feel cold air around your windows during the winter or notice that certain rooms are consistently warmer or colder than others, your existing windows may not be providing the level of insulation your home needs. For homeowners in Colorado’s mountain communities and along the Front Range, where temperatures can change significantly throughout the year, window performance can be an important part of maintaining a comfortable home.
Can Energy-Efficient Windows Lower Heating and Cooling Costs?
Energy-efficient replacement windows are designed to reduce heat transfer through the glass and frame. Features such as insulated glass, multiple panes and Low-E coatings can improve a window’s thermal performance.
Reducing unwanted heat transfer can help your home maintain a more consistent indoor temperature. In turn, your heating and cooling systems may not need to work as hard to compensate for outdoor conditions.
However, there is no universal amount that every homeowner will save by replacing their windows. Potential energy savings depend on factors including the home’s age, existing windows, insulation, HVAC system, window orientation, local climate and how efficiently the home is sealed overall.
That means new windows should be viewed as one part of a home’s overall energy-efficiency strategy rather than a guaranteed way to reduce a specific amount from your monthly utility bill.
What Should Colorado Homeowners Look for in Replacement Windows?
When comparing replacement windows, look beyond appearance and price. Energy performance, durability and proper installation should also be part of the decision.
Marvin windows offer Colorado homeowners a range of options designed around performance, durability and design flexibility. Depending on the product and configuration, homeowners can choose features such as multiple panes of glass and Low-E coatings to help manage heat transfer and meet the needs of their home.
When selecting replacement windows, consider:
- Insulated glass: Double- and triple-pane glass can provide greater insulation than older single-pane windows.
- Low-E glass: Low-emissivity coatings can help manage heat transfer while allowing natural light into the home.
- Energy-efficient frames: Frame materials and construction can affect a window’s overall thermal performance.
- Proper installation: Even a high-performance window needs to be properly installed and sealed to perform as intended.
The right combination of glass, frame and installation can help create a more effective barrier between your Colorado home and the outdoor elements.
Are New Windows Worth the Investment?
Energy savings are only one consideration when replacing windows. New windows may also help reduce drafts, improve indoor comfort, minimize outside noise, improve functionality and update the appearance of your home.
For homeowners in Denver, along the Front Range or in Colorado’s mountain communities, selecting windows appropriate for the home’s location and climate is especially important. Homes at higher elevations can experience cold temperatures, snow, strong sunlight and other demanding weather conditions.
If your windows are difficult to operate, visibly damaged, noticeably drafty or showing signs of condensation between glass panes, it may be worth having them evaluated.
