While Iowa is not typically associated with hurricanes, the state is highly susceptible to severe wind events, including derechos and tornadoes, which can produce wind speeds comparable to or exceeding those found in tropical storms. Our hurricane windows, engineered with laminated glass utilizing PVB or SentryGlas® interlayers, are designed to withstand significant impact from windborne debris, a critical factor during Iowa's powerful convective storms. These systems undergo rigorous testing according to ASTM E1886/E1996 standards, ensuring they can resist the high wind pressures and projectile impacts characteristic of severe Midwestern weather. Selecting windows that meet these demanding specifications provides essential protection for homes throughout Iowa, including the Des Moines area, against unpredictable and destructive storm events.
Common questions
Which hurricane windows are the best for Iowa?
The most effective hurricane windows for Iowa are those engineered with laminated glass and impact-rated frames, tested to ASTM E1886/E1996 standards for missile impact and wind pressure resistance. These specifications are crucial for withstanding the severe straight-line winds and potential debris impacts from derechos and tornadoes common in the region.
What is the difference between storm windows and hurricane windows?
Hurricane windows, often called impact windows, are permanently installed and engineered to resist direct impacts from windborne debris during severe storms, verified by rigorous testing protocols. Storm windows are typically secondary, removable units installed seasonally to offer protection against wind and rain, but they do not generally meet the same direct impact resistance standards.
Is it worth it to get impact windows in Iowa?
Given Iowa's propensity for severe thunderstorms, derechos, and tornadoes, impact windows are a highly worthwhile investment. They provide superior protection against property damage from high winds and flying debris, potentially lowering insurance costs and enhancing overall home security and resilience against unpredictable weather.
Can I install impact windows myself in Iowa?
While DIY installation might seem feasible, the performance and integrity of impact windows are critically dependent on precise installation to meet their stringent impact and wind resistance ratings. Professional installation by experienced technicians is strongly recommended in Iowa to ensure the windows function as intended and comply with building codes.
How much value do impact windows add to a house in Des Moines?
Impact windows can significantly enhance a home's value in Des Moines by offering robust protection against the severe weather threats prevalent in the Midwest. This enhanced security and reduced risk of storm damage make them a highly desirable feature, potentially leading to lower insurance premiums and increased appeal to prospective buyers.
What are the permitting or licensing quirks for impact windows in Iowa?
In Iowa, including the Des Moines area, permits are generally required for the installation of impact windows to ensure compliance with state and local building codes. While specific installer licensing requirements can vary, it is essential to work with providers who can demonstrate adherence to relevant performance standards like ASTM E1886/E1996.
