In Washington, the installation of impact windows must align with local building codes, which may incorporate provisions for seismic resistance in addition to wind and water intrusion standards, often referencing ASTM standards for performance. The prevalent housing stock, characterized by a mix of mid-century homes and more contemporary constructions, requires careful evaluation of existing window openings and structural integrity for effective integration of impact-rated glazing systems. When selecting a provider in Seattle or surrounding areas, prioritize those with a deep understanding of regional building science, a history of successful installations in coastal and seismically active zones, and a commitment to adhering to all relevant codes.
Common questions
Do hurricane impact windows really work in Washington?
While Washington is not subject to hurricanes, impact windows are engineered to withstand high winds and projectile impacts, making them highly effective against the severe windstorms and significant precipitation common to the state. They also offer added benefits for seismic resilience.
Which hurricane windows are the best for Seattle?
The optimal impact windows for Seattle are those that meet or exceed ASTM E1996 and ASTM E1886 standards for windborne debris and water resistance, and also consider seismic performance. Look for laminated glass and robust frame systems designed for longevity in a wet climate.
What is the difference between storm windows and hurricane windows?
Hurricane impact windows are a permanent upgrade, replacing existing windows with integrated impact-resistant glazing and frames designed for extreme weather. Storm windows are typically secondary, temporary additions placed over existing windows for supplemental protection.
Is it worth it to get impact windows in Washington?
Given the frequent windstorms, heavy rainfall, and seismic considerations in Washington, impact windows offer substantial value. They provide superior protection against severe weather, enhance energy efficiency in the often-cool climate, and can contribute to overall home resilience.
Can I install impact windows myself in Seattle?
Professional installation of impact windows is highly recommended in Seattle. Proper sealing, structural integration, and adherence to local building codes, which may include seismic provisions, are critical for performance and warranty. Incorrect installation can compromise the window's protective capabilities.
What factors influence the cost for impact windows in Washington?
The cost for impact windows in Washington is influenced by the window size and quantity, the specific type of impact-rated glass and frame materials selected, and the complexity of installation in diverse housing stock. Local building code requirements, including those for seismic zones, also contribute to the overall investment.
