Demystifying Window Energy Performance Labels
When it’s time to upgrade your home’s windows, understanding energy performance ratings can feel like decoding a complex puzzle. Today, let’s break down these crucial energy efficiency measurements to help you make an informed decision for your Western New York home.
Key Rating Metrics to Consider:
1. U-Factor
– Measures heat loss
– Lower numbers indicate better insulation
– Ideal for Buffalo winters: 0.30 or lower
2. Solar Heat Gain Coefficient (SHGC)
– Indicates solar radiation blocked
– Scale of 0 to 1
– Lower numbers mean less heat gain
3. Visible Transmittance (VT)
– Measures natural light allowed through
– Higher numbers mean more daylight
– Typically ranges from 0.30 to 0.70
Why These Ratings Matter in Western New York
Our region’s unique climate demands specific consideration for window performance. During harsh winters in areas like Springville and Hamburg, proper window ratings can significantly impact your heating costs and comfort level.
Recommended Ratings for Our Climate:
– U-Factor: 0.27 – 0.30
– SHGC: 0.35 – 0.40
– Air Leakage: 0.30 or less
– Condensation Resistance: 50 or higher
Understanding these ratings helps ensure you select windows that perform optimally in our local climate conditions while maximizing energy efficiency and comfort in your home.
Additional Considerations
– Double or triple-pane options
– Gas fills between panes
– Low-E coating options
– Frame materials and construction
Remember, investing in properly rated windows can lead to significant energy savings over time, especially in our variable Western New York climate. Professional installation ensures these performance ratings deliver their intended benefits.
