When selecting windows and doors for construction projects, certification programs provide crucial validation of product performance, ensuring safety, energy efficiency, and reliability. These comprehensive certification systems help architects, contractors, and homeowners make informed decisions.
Both of these associations are independent groups that solely evaluated window and door manufactures.
The National Fenestration Rating Council (NFRC) provides the industry's most recognized certification for energy performance.
Their labels display critical metrics including:
- U-Factor: Measures heat transfer and insulation effectiveness. The lower the number the better performance.
Solar Heat Gain Coefficient (SHGC): Indicates solar radiation blocking capability
Visible Transmittance: Shows the amount of natural light penetration
Air Leakage: Quantifies air infiltration resistance
--------------------------------------------------------------------------------------------------------------------------
The American Architectural Manufacturers Association (AAMA) certification focuses on structural integrity and durability. Products undergo rigorous testing for:
- Air infiltration resistance
- Water penetration resistance
- Structural load capacity
- Forced entry resistance
- Operating force requirements
Once the AAMA completes their independent testing, the windows and doors are placed into
4 Rating Categories, from poorest rating, R Class to the highest, AW
Class. Customer who choosing to use AW Class products in residential projects will experience longer life and greater performance in a residential application.
R-Class: Commonly known as Residential windows.
they are usually most economical windows and doors that are commonly sold big box stores
LC-Class: Light Commercial windows. These windows offer enhanced performance compared to R-Class.
CW-Class: Commercial Window class products are engineered for mid-rise buildings and applications where higher performance requirements exist. These windows undergo more stringent testing for increased air, water, and structural performance.
AW-Class: Architectural Window class represents the highest performance level. These windows are designed for high-rise and commercial buildings where maximum performance is essential. They must meet the most demanding standards for air infiltration, water resistance, and structural integrity.
