The destructive paths left by Hurricane Andrew in 1992 and Hurricane Irma in 2017 starkly remind us of the power of nature’s wrath. These hurricanes, known for their unprecedented force, brought to light the critical importance of preparing homes against such calamities. Among the most effective defenses are impact windows. These aren’t mere upgrades; they are essential safeguards, providing a resilient barrier against the fierce winds and surges of hurricanes. Their role in protecting homes in storm-prone areas is indispensable, proving time and again to be a necessary shield in the face of these formidable natural forces.
However, with so many options on the market, how do you choose the best impact windows for your home? In this guide, we will break down the key factors to consider when selecting a impact window.
What are Impact Windows?
Impact windows, also known as hurricane windows or storm windows, are specially designed windows that are built to withstand high winds, flying debris, and the impact of severe weather conditions such as hurricanes, tornadoes, or strong storms. These windows are made with durable materials and reinforced glass to provide an extra layer of protection for homes and buildings located in areas prone to extreme weather events.
The Glass Types of Impact Windows
To withstand the powerful, high-speed impact of hurricanes, high-quality special glass is essential.The primary glass types used in impact windows are laminated glass and tempered glass, often in combination.
Laminated Glass
Laminated glass is the most common type of glass used in hurricane impact windows. It consists of two or more layers of glass that are bonded together with an interlayer made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large, sharp pieces.
Key Characteristics of Laminated Glass
- Safety: In the event of breaking, the glass shards adhere to the plastic interlayer, reducing the risk of injury from sharp edges. This is particularly beneficial in applications where safety is a concern, such as in vehicles, skylights, and certain architectural features.
- Sound Insulation: The interlayer in laminated glass also provides sound dampening properties, which helps in reducing noise pollution.
- UV Protection: Laminated glass can block up to 99% of ultraviolet (UV) radiation, providing protection against sun damage to people and interior furnishings.
- Security and Burglary Resistance: The tough interlayer makes the laminated glass more difficult to penetrate compared to ordinary glass, providing an added layer of security.
Tempered Glass
Tempered glass, also safety glass, is made stronger than regular glass through a controlled heat or chemical treatment. This special treatment gives tempered glass unique properties, making it the first choice for the automotive and electronics industries.
Key Characteristics of Tempered Glass
- Strength: Tempered glass is approximately four to five times stronger than standard annealed (regular) glass. This increased strength makes it more resistant to breakage and impact.
- Safety: When tempered glass does break, it shatters into small, granular chunks rather than sharp, jagged shards. This characteristic reduces the risk of injury, making it a safer option, especially in areas where breakage may occur.
- Heat Resistance: Tempered glass undergoes heat treatment during the manufacturing process, causing internal reactions that allow it to withstand higher temperatures than ordinary glass.
- Durability: Tempered glass is more durable and resistant to scratches and other damage compared to regular glass. It is less likely to break in response to minor impacts.
Combination of Laminated and Tempered Glass
Some impact-resistant windows use a combination of both laminated and tempered glass to provide additional protection. Tempered glass combined with laminated glass panels may be called “impact glass,” “impact-resistant glass,” or “impact-resistant windows.” Impact-resistant glass combines tempered glass and laminated glass into a double- or triple-glazed unit, which is a type of specialized glass designed to withstand strong forces and impacts. Impact glass is perfect; it offers the advantages of both laminated and tempered glass. Glass and window companies tested doors and windows reinforced with impact glass by firing 9-pound, 2×4-inch wooden missiles at the glass at specific speeds to simulate the impact of flying debris during a hurricane. Glass is considered impact-resistant if it can withstand an impact without penetrating or breaking.
The Frame Material of Impact Windows
The frame material of impact windows plays a crucial role in their overall performance, durability, and energy efficiency. The choice of frame material can impact various aspects of the window’s functionality and aesthetics. Here are some common frame materials used in impact windows:
Aluminum Frames
- Strength and Durability: Aluminum frames are known for their strength and durability, making them suitable for impact windows. They can withstand the forces exerted during severe weather events.
- Low Maintenance: Aluminum frames are corrosion-resistant and require minimal maintenance, which is advantageous in coastal and humid environments.
- Aesthetic Options: Aluminum frames can be powder-coated or anodized to offer a variety of color options, allowing homeowners to match their architectural style.
Vinyl Frames
- Energy Efficiency: Vinyl frames provide excellent thermal insulation, contributing to energy efficiency. They help keep indoor temperatures stable, reducing heating and cooling costs.
- Low Maintenance: Vinyl frames are low maintenance, as they do not require painting or sealing. They are resistant to moisture, which is beneficial in humid climates.
- Cost-Effective: Vinyl impact-resistant windows are often cost-effective compared to other frame materials, making them a popular choice for homeowners seeking both performance and affordability.
Wood Frames
- Aesthetic Appeal: Wood frames offer a timeless and natural aesthetic that enhances a home’s charm and character. They are often chosen for their aesthetic appeal.
- Insulation: Wood provides natural insulation, helping regulate indoor temperatures. However, wood frames are typically less energy-efficient than vinyl or aluminum frames.
- Maintenance: Wood frames require regular maintenance, including painting or staining, to protect against moisture and decay. Homeowners should be prepared for ongoing upkeep.
Fiberglass Frames
- Strength and Durability: Fiberglass frames are strong and durable, similar to aluminum. They can withstand harsh weather conditions and impacts.
- Energy Efficiency: Fiberglass frames offer good thermal insulation, contributing to energy efficiency and comfort.
- Low Maintenance: Fiberglass frames are low-maintenance and resistant to moisture and UV rays.
The choice of frame material should align with the specific needs and preferences of homeowners. Factors such as climate, budget, maintenance considerations, and aesthetic preferences all play a role in selecting the most suitable frame material for impact windows. Regardless of the choice, it’s essential to ensure that the frame is designed to withstand the impact and wind pressure requirements of the region where the windows will be installed.
Key Features of High-Quality Impact Windows
High-quality impact windows are designed with several key features that distinguish them from standard windows. These features ensure superior performance, safety, and protection against severe weather conditions. Here are the key features of high-quality impact windows:
Multiple Layers of Impact-Resistant Glass
High-quality impact windows often feature multiple layers of specially designed impact-resistant glass. These layers provide exceptional strength and durability, making the windows highly resistant to damage from flying debris and high winds.
Thicker Glass Panes
Thicker glass panes are more resistant to impacts. High-quality impact windows typically use glass that is thicker than standard windows. The thickness can vary but is commonly around 7/16 to 9/16 of an inch (11 to 14 mm).
UV-Blocking Coatings
The combination of multiple layers and increased thickness ensures that the glass can withstand high-velocity impacts, such as those caused by flying debris during a hurricane. Even if the outer layer breaks, the inner layers and interlayer hold the glass together, preventing penetration and maintaining the window’s integrity.
Corrosion Resistance
If you live on the Florida, Gulf Coast, or Eastern Seaboard or in a humid environment, corrosion-resistant framing is a must-have. High-quality frames are often treated or coated to resist corrosion, ensuring long-term durability.
Energy Efficiency
High-quality impact windows are designed for energy efficiency. They have low U-factors, which measure insulation properties, and low Solar Heat Gain Coefficients (SHGC), which measure heat blockage from the sun. These features help maintain stable indoor temperatures and reduce energy consumption.
Code Compliance
High-quality impact windows are designed and tested to meet or exceed local building codes and industry standards for impact resistance and safety.
Energy Star® Certification
ENERGY STAR® recommendations are for the four climate zones in the United States – the primary heating zone (North); two combined heating and cooling zones (North/Central and South/Central); and one primary cooling zone (South). Many high-quality impact-resistant windows are Energy Star® certified, indicating that they meet strict energy efficiency standards set by the Environmental Protection Agency (EPA). Energy Star standards are a great benchmark for energy-conscious homeowners, architects, and builders. To choose the best-performing windows, it’s best to look to Energy Star standards.
Incorporating these key features into impact windows ensures their effectiveness in protecting homes and buildings from severe weather, enhancing energy efficiency, and providing long-term durability.
