What are the Most Energy-Efficient Windows in 2025?
Keeping heating and cooling costs low is a top priority for residents in Maryland, DC & Northern Virginia. That’s why more and more homeowners are opting to make energy-efficient upgrades to their property, and top-quality windows are a popular choice.
In this article, the experts at S&K Roofing discuss the most energy-efficient windows available in 2025, along with their many benefits.
6 Benefits of Energy-Efficient Windows
There’s a reason why many homeowners are opting for energy-efficient windows. They offer a wide range of benefits in the Maryland, DC & Northern Virginia climates, including:
- Lower energy bills: Because energy-efficient windows reduce heat transfer, homeowners can reduce their reliance on HVAC to maintain an ideal temperature, lowering energy bills without sacrificing comfort.
- Improved comfort: The area’s hot, humid summers and cold winters can impact your indoor comfort. With energy-efficient windows, the outdoor climate won’t impact your indoor temperatures to help maintain consistent comfort.
- Reduced condensation: Double- or triple-pane energy-efficient windows reduce the chance for condensation to form on your interior windows, especially during brutally cold winters.
- Less noise: The insulated glass and tight seals of energy-efficient windows can reduce noise pollution from streets and neighbors to give you a quieter living space.
- Lower carbon footprint: Choosing energy-efficient windows means you’re using less energy for your HVAC and reducing your greenhouse gas emissions, making new windows an eco-friendly choice.
- Increased home value: Upgrading to energy-efficient windows can draw home buyers as energy-saving features are highly desirable.
Energy Performance Ratings for Windows
When choosing energy-efficient windows, it may be helpful to rely on some of the National Fenestration Rating Council (NFRC) labels, including:
- U-Factor: A window’s U-Factor measures heat transfer. In the cold, Mid-Atlantic winters, a U-Factor of 0.30 or less is ideal.
- Solar Heat Gain Coefficient (SHGC): The SHGC measures the amount of solar radiator admitted. Opt for a SHGC of 0.25-0.40, even lower for south-facing windows.
- Visible transmittance: The amount of visible light transmitted is measured by visible transmittance (VT). A range of 0.30-0.70 balances daylight and heat control.
- Air leakage: For a tight seal, choose a window with an air leakage (AL) rating of 0.3 cfm/sq ft or less.
Your Most Energy-Efficient Window Options
Choosing the right products for window installation is key for ensuring the best performance in your home. The most energy-efficient window options include:
- Vinyl windows: Vinyl windows reduce thermal bridging or heat transfer through the frame. Plus, their internal air chambers also improve insulation.
- Wood-frame windows: Wood-frame windows have low conductivity and are often used in high-performance products from premium brands.
- Insulated windows: With multiple panes of glass filled with inert gas, insulated windows dramatically reduce heat transfer, UV penetration, and air leakage.
