Illinois' climate presents a unique set of challenges for building envelopes. The state experiences significant temperature fluctuations, from harsh, ice-laden winters to humid, storm-prone summers. This necessitates window systems engineered to withstand not only high winds and projectile impacts from severe convective storms, but also the thermal expansion and contraction that can compromise less durable materials over time. Our impact-rated windows are constructed with laminated glass—typically a polyvinyl butyral (PVB) interlayer bonded between two panes of glass—and robust, reinforced frames, meeting stringent testing protocols for resistance against windborne debris and pressure differentials.
When evaluating providers in Illinois, it is crucial to consider their familiarity with local building codes and permitting processes, which can vary by municipality. Understanding the specific requirements for wind load resistance and impact protection in your area, especially within the greater Chicago metropolitan region, is paramount. Impact Windows Direct prioritizes adherence to these regulations, ensuring that our installations not only enhance your property's resilience but also comply with all relevant state and local mandates, providing peace of mind alongside superior protection.
Common questions
What is an impact window?
An impact window is a specialized fenestration product designed to withstand extreme weather events. Its construction involves laminated glass, featuring a durable interlayer such as PVB, sandwiched between two panes of glass, and reinforced frame systems. This design provides superior resistance to high winds, projectile impacts from windborne debris, and pressure differentials, offering enhanced protection for your home.
What are the drawbacks of impact windows?
While offering significant protection, impact windows can be more expensive upfront than standard windows due to their advanced materials and construction. Some homeowners may also find the glass to be slightly thicker, potentially altering the visual profile, and the initial installation process might be more involved. However, these are often outweighed by long-term benefits like enhanced security and reduced energy costs.
What is the highest rated impact window?
The 'highest rated' impact window is determined by its performance in rigorous testing against established industry standards, such as Miami-Dade County standards or ASTM E1996 and E1886. Look for windows that have successfully passed these tests for large and small missile impacts, as well as extreme wind pressures relevant to your region's potential weather threats in Illinois.
Do hurricane impact windows really work?
Yes, hurricane impact windows are engineered and rigorously tested to effectively withstand the forces of severe weather. They are designed to prevent breakage from windborne debris and maintain structural integrity under high wind loads, thereby protecting interiors from water intrusion and catastrophic damage, which is crucial for properties in vulnerable areas.
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 complexity of the frame, the specific impact resistance rating required, and the scope of the installation project. Because of these variables, providing an average cost without a detailed assessment of your specific needs would be imprecise. We recommend obtaining a personalized quote.
What are the drawbacks of impact windows in Chicago?
In Chicago, the primary considerations for impact windows, beyond their protective capabilities against severe storms and hail, are their thermal performance during extreme winter conditions and their ability to meet local building codes. While offering superior strength, the initial investment is higher than standard windows, and ensuring proper installation to maintain structural integrity and energy efficiency is key.
