The District of Columbia experiences a temperate climate with distinct seasons, but it is particularly vulnerable to severe weather events such as intense thunderstorms capable of generating damaging winds and airborne debris. The housing stock, a diverse mix of historic row houses, modern apartments, and commercial buildings, can all benefit from upgraded window systems. Impact-resistant windows, engineered to meet rigorous testing protocols including ASTM E1996 and E1886, offer a critical layer of defense by preventing glass failure under extreme pressure and impact. Our meticulous installation ensures these systems perform as intended, safeguarding your property.
Common questions
What are the drawbacks of impact windows?
A primary consideration with impact windows involves their initial procurement and installation expense, which is generally higher than standard glazing due to the specialized materials and construction. Some homeowners also note a slight reduction in visible light transmission or a subtle tinting effect, depending on the specific product's coatings and laminate composition. However, these factors are often outweighed by the long-term benefits of enhanced security and protection.
What is the highest rated impact window?
Determining the 'highest rated' impact window involves evaluating products against established industry standards, such as Miami-Dade County protocols or ASTM E1996 and E1886, which certify resistance to wind pressure and projectile impact. Manufacturers like PGT, Simonton, and Andersen offer lines that consistently meet or exceed these rigorous testing requirements, providing proven performance in severe weather conditions.
What is the average cost of hurricane windows?
The cost of hurricane impact windows is influenced by numerous variables, including the size and number of units required, the specific product line and its performance ratings, the complexity of the installation site, and any necessary modifications to existing window openings. Factors such as the type of frame material—whether vinyl, aluminum, or reinforced composite—and the specific glazing technology employed also play a significant role in the overall investment.
Do hurricane impact windows really work?
Yes, hurricane impact windows are engineered and rigorously tested to withstand significant wind loads and impacts from airborne debris, a critical function during severe weather events. By incorporating laminated glass, typically two panes of glass bonded with a strong interlayer such as polyvinyl butyral (PVB), and robust frame systems, these windows effectively prevent glass fragmentation and penetration, thereby protecting interiors from wind and water intrusion.
Which hurricane windows are the best?
The 'best' hurricane windows are those that comprehensively meet or exceed relevant building codes and impact resistance standards, such as those set by Miami-Dade County or ASTM. Factors to consider include the window's design pressure (DP) rating, its ability to resist specific missile impacts (Level 1 or Level 2), frame material strength (e.g., reinforced vinyl or aluminum), and the quality of the laminate interlayer used in its construction.
How do impact windows benefit Washington D.C. properties?
Impact windows offer Washington D.C. properties enhanced protection against severe thunderstorms and strong winds prevalent in the region. Their laminated glass composition is designed to withstand impacts from wind-borne debris, preventing breakage and subsequent water intrusion. This significantly reduces the risk of interior damage and contributes to a more secure and resilient building envelope.
