Have you ever wondered what makes a window or door truly energy-efficient?
It’s not just about the glass or the frame; it’s about how well they perform together, tested and verified by a trusted authority. Enter the National Fenestration Rating Council (NFRC), your compass in the vast sea of fenestration options.
Understanding NFRC Ratings
What are NFRC Ratings?
NFRC ratings offer a standardized way to gauge the energy performance of windows, doors, and skylights. Think of them as nutrition labels, but for your building’s openings. These ratings, including U-factor, solar heat gain coefficient (SHGC), and visible transmittance (VT), provide a clear picture of how products will perform in real-world conditions.
Key Components of NFRC Ratings
- U-Factor: Measures how well a product can keep heat from escaping. Lower numbers mean better insulation.
- Solar Heat Gain Coefficient (SHGC): Measures how much solar radiation is admitted through a window. Lower numbers mean less heat entering, which is ideal in hot climates.
- Visible Transmittance (VT): Measures how much natural light is let in. Higher numbers mean more light and potentially less need for artificial lighting.
How Ratings are Determined
The NFRC conducts thorough testing in controlled environments to ensure accurate ratings for windows, doors, and skylights. These tests simulate various climate conditions to provide reliable performance data.
Benefits of NFRC-Certified Steel Windows and Doors
NFRC-certified products not only promise excellent energy performance but also help you save money on heating and cooling. They also contribute to a sustainable environment by reducing carbon footprints. Furthermore, using NFRC-rated products ensures compliance with local energy codes, making your construction project smoother.
Why Choose NFRC-Certified?
- Compliance with energy standards like Title 24

Factors Affecting NFRC Ratings of Steel Windows and Doors
The design and material of steel windows and doors significantly influence their NFRC ratings. Factors like the type of glazing, the presence of thermally broken frames, and the overall design play crucial roles.
Design and Material Impact
- Thermally broken steel products offer superior insulation, reducing energy loss.
- The choice of glazing can affect both U-factor and SHGC, impacting overall energy efficiency.
Comparing NFRC Ratings: Steel vs. Other Materials
Steel windows and doors often outperform other materials like aluminum or wood, thanks to their durable and efficient design. Let’s dive into a comparison, highlighting the strengths of steel in energy performance.
Performance Showdown
| Material | U-Factor | SHGC | Durability |
|---|---|---|---|
| Steel | Low | Varied | High |
| Aluminum | Medium | High | Medium |
| Wood | High | Low | High |
