Impact Window Basics

Impact windows, often called hurricane windows, are specifically designed to withstand intense weather conditions. These windows offer home protection that is far beyond what a normal window offers. They are especially popular (and sometimes required) in areas prone to hurricanes, tornadoes, and other extreme weather events, but their benefits extend to any homeowner seeking durability, energy efficiency, and added security. Let’s dive into what makes these windows unique, why they’re worth considering, and what you need to know about installation and costs.

What Are Impact Windows?

Impact windows are specially engineered with safety glass to resist shattering, even under extreme force. That means they include multiple layers of glass and a durable interlayer (often polyvinyl butyral, or PVB) that holds the glass intact when struck. This technology prevents the window from breaking apart, reducing the risk of dangerous glass shards shattering into your home and keeping your home’s interior protected.

Impact windows undergo rigorous testing to ensure they can withstand both high wind speeds and direct impact from debris. As a result, they’re an excellent choice for anyone looking to bolster their home’s defenses against natural disasters, as well as to improve safety, energy efficiency, and noise reduction.

Be aware that these windows are sometimes mistakenly called storm windows. However, contractors install storm windows over/on top of an existing window in your home. Impact windows, on the other hand, function like any other window installed directly into your home’s structure.

Why Homeowners Choose Hurricane Windows

Here are some of the key benefits that make these windows a solid investment for any household.

Protection During Severe Weather

Impact windows provide a protective barrier during storms, preventing debris from entering the home. This feature is critical in hurricane-prone areas where wind-borne debris can cause substantial damage. In many cases, they also meet building code requirements for storm protection in coastal regions, giving homeowners peace of mind during hurricane season.

Enhanced Security

Because of their shatter-resistant design, impact windows are much more difficult to break into than traditional windows. The additional layer of security makes them a good deterrent against forced entry, enhancing overall home safety.

Improved Energy Efficiency

Impact windows aren’t just strong; they’re also energy-efficient. They’re designed with insulated glass that helps reduce heat transfer, maintaining comfortable indoor temperatures and reducing reliance on heating and cooling systems. This energy efficiency can lead to long-term savings on utility bills, particularly in regions with intense sunlight or extreme temperatures.

Noise Reduction

One of the often-overlooked benefits of impact windows is their ability to reduce noise pollution. The thick, multi-layered glass acts as an effective sound barrier, making them ideal for homes located near busy roads, airports, or other noisy environments. With these windows, you can enjoy a quieter, more peaceful indoor space.

Longevity

With proper care and maintenance, impact windows can last 20 years or more. Many manufacturers offer long-term warranties, underscoring their durability and the expected longevity of the materials.

Types of Impact Windows

You’ll find a range of impact windows available from many manufacturers, each with unique materials and styles to match different aesthetic preferences and functional needs. Here are some of the most common types.

Material Options

  1. Vinyl: Vinyl is a durable, low-maintenance, cost-effective material. It offers natural insulation and is resistant to moisture, making it a good choice for many homes.
  2. Aluminum: Aluminum frames are lightweight yet strong, and they provide excellent resistance to corrosion and weathering. This material is popular for homes in coastal areas due to durability and sleek appearance.
  3. Composite: Composite materials blend various materials to enhance strength, insulation, and appearance. Composite windows are versatile and can often be customized to suit unique design preferences.

Popular Styles

  1. Single-Hung and Double-Hung Windows: These classic window styles have one or two sashes that can be raised or lowered, making them easy to operate and providing ventilation when desired.
  2. Fixed Windows: Fixed impact windows do not open, but they’re a great option for maximizing light and providing an unobstructed view. These windows work well in areas where ventilation isn’t a priority, such as higher walls or large picture windows.
  3. Sliding Windows: Sliding windows are popular for ease of use and clean lines. They provide a modern look while offering impact resistance and are especially suited for wide window openings.
  4. Casement Windows: Casement windows hinge at the side and open outward, allowing for maximum ventilation. They provide a tight seal when closed, enhancing their energy efficiency.

Impact Resistant Windows Installation Process

Choosing impact windows is a significant decision, and proper installation is crucial to ensuring they perform effectively. Here’s what to expect during the installation process.

Choosing a Reliable Installer

Professional installation is the key to window effectiveness. It’s essential to work with a contractor who’s experienced with impact-resistant products. Find an installer who’s certified by window manufacturers, ensuring they follow precise installation standards and procedures. A reputable installer will also be able to guide you through product selection based on your specific needs.

What to Expect During Installation

Installation typically begins with removing existing windows and preparing the opening for the new impact windows. The installer will ensure a secure fit by leveling the frame, adding weatherproofing measures, and sealing any gaps. The process can take anywhere from a few hours for single windows to several days for full-home installations, depending on the scope of the project.

Tips for Home Preparation

To prepare your home for impact window installation, you should remove any window treatments, such as blinds or curtains, that are in the way. Cover furniture and flooring near the installation site to protect your belongings from dust or debris. Your installer should provide you with a clear timeline and instructions for any additional preparation.
