Pennsylvania's climate presents a unique set of challenges for building envelopes, necessitating window systems capable of withstanding high winds, projectile impacts from debris during severe convective storms, and the thermal cycling common to its four distinct seasons. The primary housing stock, often comprised of older brick and frame constructions, can be particularly vulnerable to the stresses imposed by these events. Therefore, the selection of impact-resistant glazing becomes a critical factor in safeguarding property integrity and minimizing potential damage. Our installation process adheres to stringent ASTM standards, ensuring each unit functions as a vital component of your home's defense against the elements.
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.
What are the drawbacks of impact windows in Philadelphia?
While primarily offering benefits, impact windows can present a higher initial investment compared to standard windows. In Philadelphia's climate, the most significant drawback might be the perceived over-engineering for events less frequent than in tropical zones, though their resistance to hailstorms and severe thunderstorms provides tangible value. Aesthetic considerations, such as the slight tinting or increased frame thickness, are also factors some homeowners evaluate.
