Impact windows & doors in Illinois
Last updated: September 24, 2026
Illinois experiences a wide array of weather phenomena, from severe thunderstorms and tornadoes in the spring and summer to harsh winter blizzards and extreme cold. For residents in the Chicago metropolitan area and throughout the state, the need for robust fenestration solutions is driven by these significant seasonal weather fluctuations.

In Illinois, the primary considerations for impact windows and doors revolve around the significant threat of severe thunderstorms, including high winds and the potential for tornado-driven debris, as well as the extreme conditions posed by winter storms. Our impact-rated products are engineered to adhere to rigorous building codes, often meeting or exceeding ASTM E1886/E1996 standards for windborne debris impact and cyclic pressure resistance, vital for compliance and safety. The predominant housing stock, encompassing historic Chicago architecture and more contemporary suburban residences, demands solutions that offer both aesthetic integration and superior structural performance. Understanding the specific wind zone classifications and debris impact requirements relevant to your property's location within Illinois is crucial for selecting the most appropriate and effective impact fenestration system.
Common questions
What is the highest rated impact window?
The highest-rated impact windows are those that have undergone rigorous third-party testing and meet or exceed industry standards such as ASTM E1886/E1996. These products are designed to withstand extreme wind speeds and projectile impacts, offering superior protection against severe weather events prevalent in areas like Illinois. Look for manufacturers who provide independent certification for their products' performance metrics.
What is the average cost of hurricane windows?
The cost of hurricane impact windows is influenced by factors such as the size and type of window, the specific impact-resistant materials utilized (e.g., laminated glass, reinforced frames), and the complexity of installation. While a precise average cost cannot be stated without a site-specific assessment, the investment reflects the advanced engineering and materials required for robust protection against severe weather in Illinois. A detailed phone quote is the most accurate way to ascertain project-specific pricing.
Do hurricane impact windows really work?
Yes, hurricane impact windows and doors are engineered to provide significant protection against high winds and flying debris during severe weather events. Their construction, typically involving laminated glass and reinforced frames, is designed to resist penetration and maintain structural integrity, demonstrably reducing the risk of damage and enhancing safety in regions like Illinois. Independent testing validates their efficacy.
Which hurricane windows are the best?
The 'best' hurricane windows are those that meet or surpass the most stringent impact and wind resistance standards relevant to your specific geographic location within Illinois. Consider windows with robust frame materials, such as reinforced vinyl or extruded aluminum, and multi-layered laminated glass that adheres to ASTM E1886/E1996 specifications. Evaluating a provider's adherence to these technical specifications is key.
What is the difference between storm windows and hurricane windows?
Storm windows are typically temporary or secondary window units installed over primary windows for added protection during inclement weather, whereas hurricane impact windows and doors are integrated, permanent fenestration systems designed to withstand extreme wind forces and projectile impacts as defined by standards like ASTM E1886/E1996. Impact windows offer a higher level of protection and are a code requirement in many hurricane-prone areas.
What impact window specifications are most important for Illinois?
For Illinois, the most critical impact window specifications include resistance to high wind speeds and projectile impacts, as defined by ASTM E1886/E1996 standards. Given the state's susceptibility to severe thunderstorms and tornadoes, ensuring windows can withstand significant pressure differentials and resist penetration from windborne debris is paramount for structural integrity and occupant safety.
