If you’re considering installing impact windows for hurricane protection, you may wonder whether there are different grades available. The answer is yes! Impact windows are classified into various grades based on factors like glass strength, wind pressure resistance, debris impact ratings, and frame materials. Understanding these grades can help you choose the right windows for your home in a hurricane-prone area like Broward County.
Factors that Determine the Grades of Impact Windows
- Glass Type The type of glass used plays a crucial role in determining the grade of impact windows. The higher the quality and strength of the glass, the better the grade:
- Laminated Glass: This glass consists of multiple layers, offering excellent durability and protection against breakage.
- Tempered Glass: Stronger than regular glass, tempered glass is used alongside laminated glass in high-grade windows to prevent shattering into dangerous shards.
- Insulating Laminated Glass: Provides enhanced insulation for energy savings while offering hurricane protection.
- Wind Pressure Resistance Different grades of impact windows are tested to withstand various wind pressures. Windows with higher wind resistance are ideal for areas with more severe hurricanes.
- Basic Grade: Rated for wind speeds of 130-150 mph, typically for regions with moderate hurricane risks.
- Premium Grade: Rated for winds exceeding 150 mph, offering maximum protection during category 4 or 5 hurricanes.
- Debris Impact Resistance Impact windows are graded based on their ability to withstand flying debris, which is critical during hurricanes:
- Small Missile Impact: Tested against smaller debris like roof gravel.
- Large Missile Impact: Tested against larger debris such as tree branches and 2×4 boards, making them suitable for areas with stronger storms.
- Frame Materials Impact windows are also graded based on the materials used in their frames:
- Aluminum Frames: Offer great strength and are lightweight, often found in high-grade windows.
- Vinyl Frames: Provide solid protection and are common in mid-grade windows. They are more affordable than aluminum but still highly durable.
- Certifications and Building Codes The grade of an impact window is validated by certifications from governing bodies, such as:
- Miami-Dade Approval: One of the strictest certifications, ensuring the windows can handle the toughest hurricane conditions.
- ASTM and NFRC Standards: Additional testing to measure impact resistance, air infiltration, and thermal performance.
Glass Options to Consider for Impact Windows
Impact windows come with different glass options that enhance their performance and determine their grade:
- Heat-Strengthened Glass: Offers additional resistance to wind pressure and thermal stress, reducing the likelihood of breakage.
- Low-E Glass: Provides excellent energy savings by minimizing the amount of ultraviolet and infrared light that passes through, while still allowing visible light.
- Laminated Glass: Known for multi-functional benefits, including UV protection, sound control, and superior hurricane resistance.
- Insulating Laminated Glass: Combines the benefits of insulation and hurricane protection, making it an excellent choice for both energy savings and safety.
How to Choose the Right Grade of Impact Windows for Your Home
When choosing the grade of impact windows for your home, consider:
- Your Local Building Codes: Areas like Broward County have strict regulations, especially for homes in high-risk zones.
- Wind Exposure: Homes near the coast may require higher-grade windows due to stronger wind exposure.
- Budget: Higher-grade impact windows offer more protection but may come at a higher cost. However, they often lead to savings on insurance premiums and energy costs.
