The market offers a variety of solutions, each designed to meet different needs and budgets. From advanced glass technologies to robust frame materials, the components of impact resistant windows work together to create a formidable barrier. This article will guide you through the essential aspects of selecting the best impact resistant windows, ensuring your home remains safe and secure.
Understanding Impact Resistant Windows
Impact resistant windows are engineered to withstand significant force without shattering, unlike standard windows. Their primary purpose is to prevent debris from penetrating your home during high winds and to deter forced entry. This resilience is achieved through a combination of specialized glass and reinforced frames.
At the core of these windows is laminated glass, often featuring a strong, clear interlayer bonded between two panes of glass. This interlayer holds the glass together even if it cracks, preventing a gaping hole in your home’s envelope. The frames are also designed to be exceptionally strong, securely holding the glass in place under extreme pressure.
Key Benefits of Choosing Impact Resistant Windows
Superior Storm Protection: The most significant benefit is their ability to withstand hurricane-force winds and flying debris, protecting your home’s interior from water damage and structural compromise.
Enhanced Security: Impact resistant windows make it much harder for intruders to break in, adding an extra layer of security to your property.
Noise Reduction: The laminated glass construction also provides excellent sound insulation, significantly reducing outside noise.
UV Protection: Many impact resistant window options block a high percentage of harmful UV rays, protecting your furniture and flooring from fading.
Energy Efficiency: Modern impact resistant windows often come with energy-efficient features, helping to reduce heating and cooling costs.
Types of Impact Resistant Glass
When searching for the best impact resistant windows, understanding the different types of glass available is essential. The strength and performance of the window largely depend on its glass composition.
Laminated Glass with PVB or SGP Interlayers
The most common type found in impact resistant windows is laminated glass. This involves bonding two or more panes of glass with a flexible, transparent interlayer. Polyvinyl Butyral (PVB) is a common interlayer material, known for its ability to hold glass fragments together upon impact. For even greater strength and stiffness, SentryGlas Plus (SGP) interlayers are used, often in areas requiring extreme protection.
Annealed, Heat-Strengthened, and Tempered Glass Combinations
While the interlayer provides the impact resistance, the outer glass panes can be annealed, heat-strengthened, or fully tempered. Annealed glass is standard glass. Heat-strengthened glass is stronger than annealed but not as strong as tempered. Fully tempered glass is the strongest and shatters into small, blunt pieces when broken. Often, impact resistant windows combine a tempered or heat-strengthened outer pane with an annealed inner pane and a robust interlayer for optimal performance.
Frame Materials for Best Impact Resistant Windows
The frame plays a critical role in the overall integrity of impact resistant windows. A strong frame is necessary to hold the laminated glass securely during an impact event. Several materials are commonly used, each offering distinct advantages.
Vinyl Frames
Vinyl frames are a popular choice due to their durability, low maintenance, and excellent energy efficiency. They are often reinforced with steel or aluminum to meet impact resistance standards. Modern vinyl frames for impact resistant windows are designed to be robust and long-lasting.
Aluminum Frames
Aluminum frames are known for their strength and sleek appearance. They are inherently strong and can withstand significant forces, making them a good candidate for impact resistant windows. However, traditional aluminum can be less energy-efficient than other materials, though newer designs incorporate thermal breaks to improve performance.
Fiberglass Frames
Fiberglass frames offer an excellent balance of strength, durability, and energy efficiency. They are dimensionally stable, meaning they resist expansion and contraction with temperature changes, which helps maintain the window’s seal and integrity over time. Fiberglass is a premium option for best impact resistant windows.
Key Features to Look for in Impact Resistant Windows
When evaluating different options, several features distinguish the best impact resistant windows from standard alternatives. Focusing on these aspects will ensure you choose a product that offers maximum protection and value.
Certifications and Ratings
Always look for certifications from reputable organizations. In hurricane-prone regions, certifications from Miami-Dade County, Florida Building Code (FBC), Texas Department of Insurance (TDI), or testing standards like ASTM E1886/E1996 are crucial. These indicate that the impact resistant windows have undergone rigorous testing to prove their ability to withstand high winds and large missile impacts.
Glass and Frame Strength
Beyond the certifications, inquire about the specific glass thickness and interlayer type. Also, consider the frame’s construction, including any internal reinforcements. The best impact resistant windows will feature heavy-duty components designed for extreme conditions.
Energy Efficiency Ratings
Look for the National Fenestration Rating Council (NFRC) label, which provides objective information on a window’s energy performance. Key metrics include U-factor (heat transfer), Solar Heat Gain Coefficient (SHGC – solar radiation blocked), and Visible Transmittance (VT – light allowed through). High-performance impact resistant windows often excel in these areas.
Hardware and Locking Mechanisms
The hardware and locking systems on impact resistant windows should be robust and durable. Multi-point locking systems, strong hinges, and corrosion-resistant materials contribute significantly to both security and longevity.
Professional Installation: A Critical Component
Even the best impact resistant windows will fail to perform optimally if not installed correctly. Professional installation is paramount to ensure that the windows meet their intended performance standards.
Experienced installers understand the specific requirements for anchoring impact resistant windows to your home’s structure, often using specialized fasteners and sealants. Proper installation ensures that the window system can withstand the forces it was designed for, maintaining the integrity of your home’s envelope during severe weather.
Top Considerations When Choosing Impact Resistant Windows
Making the right choice involves weighing several factors unique to your situation and location. These considerations will help narrow down your options for the best impact resistant windows.
Local Building Codes and Requirements
Always check your local building codes. In many hurricane-prone areas, impact resistant windows are either mandated or highly recommended to meet specific wind-borne debris protection standards. Ensuring compliance is essential for your safety and for obtaining necessary permits.
Climate and Specific Threats
Consider the specific environmental threats your home faces. While all impact resistant windows offer enhanced security, the level of storm protection needed might vary depending on your region’s susceptibility to hurricanes, tornadoes, or other severe weather events.
Budget and Warranty
Impact resistant windows are an investment, and prices can vary significantly based on materials, features, and brand. Balance your budget with the level of protection and energy efficiency you desire. Also, thoroughly review the warranty offered by manufacturers and installers, covering both the product and the installation.
