North Carolina's climate is diverse, with coastal regions facing potential threats from hurricanes and tropical storms, while inland areas like Charlotte and Raleigh experience severe thunderstorms with high winds and hail. The state's housing stock is varied, encompassing historic homes, coastal properties, and modern constructions, each requiring tailored impact window solutions. Permitting and building codes in North Carolina, particularly along the coast, are stringent regarding wind resistance and storm preparedness, often referencing standards like the Florida Building Code or Miami-Dade County protocols. Our impact windows are engineered to meet and exceed these requirements, providing a robust defense against windborne debris and extreme weather, ensuring the safety and security of your home or business.
Common questions
What is an impact window?
An impact window is a specialized window system designed to withstand high winds and projectile impacts common in severe weather. It features laminated glass, consisting of two panes of glass bonded by a strong, transparent interlayer such as PVB or SGP. This construction prevents the glass from shattering upon impact, maintaining the window's integrity.
What are the drawbacks of impact windows?
The primary drawbacks of impact windows include a higher initial cost compared to standard windows and a potential for slightly reduced light transmission due to the laminated glass. Some users may also perceive a minor distortion in visibility. The increased weight of the glass can also necessitate reinforced framing systems.
What is the highest rated impact window?
The 'highest rated' impact window is generally considered one that meets or exceeds stringent testing standards such as those established by Miami-Dade County (TAS 201, TAS 202, TAS 203) and ASTM E1886/E1996. These certifications indicate superior performance in impact resistance and cyclic pressure testing.
How much does one impact window cost?
The cost of a single impact window is influenced by its dimensions, the frame material used (e.g., vinyl, aluminum), the specific type of laminated glass, and any additional features. The complexity of the installation process, including the need for custom framing or structural adjustments, also affects the overall expense.
What is the average cost of hurricane windows?
The average cost for hurricane windows is determined by a variety of factors, including the total number of windows required, their specific measurements, the chosen frame materials, and the impact resistance ratings mandated by local building codes. The scope and intricacy of the installation project are also significant cost factors.
What is an impact window?
An impact window is a robust window system engineered to resist significant forces from windborne debris and extreme pressure fluctuations. It comprises laminated glass, where a tough interlayer adheres the glass panes together, preventing them from breaking apart and thus maintaining the window's barrier function.
