Yes, there are different grades of impact windows. They vary in strength, materials, storm rating, and energy efficiency, depending on the manufacturer and the level of protection needed.
The grade of an impact window typically refers to its performance under pressure, and these grades depend on different factors like glass thickness, frame strength, and testing certifications, such as Miami-Dade or American Society for Testing and Materials (ASTM) standards. For example, windows approved by the Miami-Dade County Product Control Division are tested under some of the toughest standards in the country. These windows are rated to withstand large missile impacts and high wind zones, making them suitable for areas with frequent hurricanes.
Impact window performance is often rated using the Performance Grade (PG) system, which includes Design Pressure (DP) ratings. A higher DP rating means the window can resist stronger wind loads and impacts. Other features, like the type of interlayer (usually PVB) and locking systems, also play a role in the window’s overall strength and durability. Choosing the right grade depends on your location, budget, and the level of protection you want. Investing in a top-grade impact window can provide better long-term value, safety, and peace of mind. Always consult a certified installer or window specialist to understand which grade best suits your home or building.
