In Minnesota, the primary drivers for impact window consideration stem from the extreme temperature differentials experienced between frigid winters and warm, often humid summers. While not subject to hurricane-force winds, the state frequently endures severe thunderstorms and derechos that can generate damaging straight-line winds exceeding 70 mph, posing a significant threat to conventional glazing. Furthermore, the substantial weight and abrasive nature of heavy snowfall can exert considerable pressure on window frames and seals over time, underscoring the need for durable construction and robust materials such as laminated glass with polyvinyl butyral (PVB) interlayers and reinforced vinyl or aluminum frames.
When evaluating impact window providers in the Minneapolis area and across Minnesota, it is imperative to scrutinize product specifications for adherence to relevant building codes and performance standards. Look for windows certified to meet or exceed ASTM E1886/E1996, the primary standards for windborne debris impact resistance, even if not mandated by local code for non-coastal regions. Understanding the specific wind load ratings and air/water infiltration test results, alongside the quality of the frame construction and the type of impact-resistant glass employed (e.g., laminated tempered glass), will provide a clear indication of a product's inherent resilience and long-term performance against Minnesota's unique environmental challenges.
Common questions
What are the drawbacks of impact windows?
While offering substantial protection, the primary drawback of impact windows can be their initial investment cost compared to standard glazing. Additionally, some laminated glass options might exhibit a slightly reduced visible light transmission or a subtle tint. However, these are often outweighed by enhanced security, reduced noise infiltration, and improved energy efficiency over the lifespan of the product.
What is the highest rated impact window?
The 'highest rated' impact window is contingent upon specific performance metrics like wind load resistance (e.g., TAS 201, TAS 202, TAS 203) and impact resistance standards (e.g., ASTM E1886/E1996). Manufacturers often submit their products for independent testing to achieve various Miami-Dade County approvals, which are among the most stringent in the industry, indicating superior performance.
What is the average cost of hurricane windows?
The cost of impact windows is influenced by numerous factors, including the size and type of the window, the materials used for the frame (e.g., vinyl, aluminum, reinforced vinyl), the specific impact rating of the laminated glass, and the complexity of the installation.

Do hurricane impact windows really work?
Yes, hurricane impact windows are engineered and rigorously tested to withstand significant wind pressures and projectile impacts, such as those generated by severe storms. Their construction, typically involving laminated glass bonded with a strong interlayer, prevents shattering and maintains the integrity of the window opening, thereby protecting the interior of the home from wind and water intrusion.
Which hurricane windows are the best?
The 'best' hurricane windows are those that meet or exceed the specific building code requirements for your region and are manufactured by reputable companies adhering to stringent testing protocols like ASTM E1886/E1996. Consideration should also be given to frame material durability, hardware quality, and the specific type of impact-resistant glass and interlayers utilized for optimal performance.
What are the drawbacks of impact windows in Minnesota?
While Minnesota does not face direct hurricane threats, the severe weather, including high winds from thunderstorms and derechos, can still stress standard windows. Impact windows offer enhanced protection against such events, and their primary drawbacks are generally related to initial cost. However, the long-term benefits of reduced energy loss and increased security often mitigate these concerns over time.
