In Oklahoma, the installation of impact windows is critically important due to the state's high frequency of severe weather, including devastating tornadoes and large hail events that pose a substantial threat to property integrity. The building codes in Oklahoma are designed to address these risks, often referencing stringent standards such as ASTM E1886/E1996 for missile impact resistance and wind load capacity, ensuring that fenestration products can withstand the extreme forces generated by these meteorological phenomena. When seeking impact window solutions in Oklahoma, particularly for areas around Oklahoma City and Tulsa, it is essential to partner with providers who demonstrate a thorough understanding of state and local building requirements, the specific wind zone classifications applicable to your property, and possess experience with the diverse housing stock prevalent in the region, from traditional farmhouses to modern suburban homes, thereby ensuring that the installed impact window systems meet or exceed all mandated safety and performance criteria.
Common questions
What is an impact window?
An impact window is a specialized fenestration product designed to withstand extreme weather conditions, incorporating a robust frame and a laminated glass pane. This multi-layered glass, typically consisting of two panes of glass bonded by a strong interlayer such as polyvinyl butyral (PVB), resists shattering upon impact from windborne debris, thereby maintaining the building's structural integrity during severe storms.
What are the drawbacks of impact windows?
While offering significant protection, impact windows can present certain drawbacks, including a higher initial material cost compared to standard windows due to the specialized laminated glass and reinforced frames. Some homeowners also note a slight distortion in visibility or a darker tint depending on the specific product's composition and UV protective coatings, and installation can require professional expertise to ensure optimal performance and seal integrity.
What is the highest rated impact window?
The highest rated impact windows are those that have undergone rigorous testing and achieved superior ratings according to established industry standards such as ASTM E1886/E1996 for missile impact and wind pressure resistance. These products are engineered with advanced materials and construction techniques to offer maximum protection against severe weather events, often exceeding basic code requirements for residential and commercial applications.
What is the average cost of hurricane windows?
The cost of hurricane impact windows is influenced by numerous factors including the size and type of the window, the complexity of the design, the specific performance ratings required (e.g., wind load and impact resistance levels), and the materials used in their construction. The scope of the project, involving the number of windows to be replaced and any necessary structural modifications for installation, also plays a significant role in the overall investment, and a precise estimate is best obtained through a professional assessment.
Do hurricane impact windows really work?
Yes, hurricane impact windows are engineered to effectively withstand the forces of hurricanes and severe storms. Their laminated glass and reinforced frames are designed to resist penetration by windborne debris traveling at high velocities, preventing the catastrophic failure of the building envelope that can occur when standard windows break, thus providing a critical layer of defense.
Are impact windows necessary in Oklahoma?
Yes, impact windows are highly recommended in Oklahoma due to the frequent and severe weather events, including tornadoes and large hail, that pose a significant risk to property. Their ability to resist high winds and projectile impacts, as validated by standards like ASTM E1886/E1996, provides crucial protection for homes and businesses throughout the state, significantly enhancing structural resilience.
