In Georgia, the primary impetus for impact window installation stems from the need to mitigate damage from severe thunderstorms, which frequently produce damaging winds, large hail, and flying debris, as well as the potential for tropical storm remnants impacting the southern regions. Georgia's building codes align with national standards, often referencing ASTM E1886/E1996 for projectile impact resistance and wind load calculations, ensuring that fenestration products offer adequate protection against these threats. When selecting an impact window provider in Georgia, particularly within the Atlanta and Columbus metro areas, it is essential to verify their familiarity with local building regulations, the specific wind zone classifications applicable to your property, and their experience with the common housing styles prevalent throughout the state, ranging from historic homes to modern constructions, ensuring that the chosen impact window systems meet or exceed all mandated performance criteria and contribute to the overall durability of the structure.
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.
How do I choose an impact window provider in Atlanta?
When selecting an impact window provider in Atlanta, ensure they are knowledgeable about Georgia's building codes and wind zone classifications. Verify their experience with the varied housing styles in the metropolitan area and request proof of their adherence to standards like ASTM E1886/E1996 for projectile impact resistance. A thorough review of their installation processes and warranty terms is recommended for optimal protection.
