NFRC Label & ENERGY STAR® Qualification
Energy Performance Testing, Certification, & Labeling
At Five Seasons, we prioritize energy efficiency, and that's why we adhere to the standards set by the National Fenestration Rating Council (NFRC). Through their voluntary program, the NFRC rigorously tests, certifies, and labels windows, doors, and skylights based on their energy performance ratings. This means you can trust the NFRC label as a reliable indicator of a product's energy properties and use it for easy comparison when selecting energy-efficient solutions for your home.
Look out for the NFRC label on all our ENERGY STAR® qualified window and door products. ENERGY STAR focuses its qualification primarily on U-factor and solar heat gain coefficient ratings, ensuring that you get products that meet high energy efficiency standards.
Understanding Heat Gain & Loss
When it comes to energy performance, windows and doors play a crucial role in minimizing heat gain and loss. They can impact your home's energy efficiency through:
- Direct conduction & convection: Heat Transfer Through Material
- Thermal radiation: Emission of Heat Waves
- Solar radiation absorption: Absorption of Sun's Energy
- Air leakage:
Unwanted Air Passage
Key Energy Performance Characteristics
Our products are designed and rated based on essential energy performance characteristics:
- U-Factor:
Measures heat transfer rate through the window - Solar Heat Gain Coefficient (SHGC):
Measures how well the window blocks heat from sunlight - Air Leakage: Measures the rate of air movement around windows and doors
