This comprehensive guide delves into the world of impact-resistant exterior windows, exploring their benefits, features, costs, installation process, and everything you need to know to make an informed decision for your home.

What are Impact Resistant Windows?

Impact-resistant windows, often referred to as hurricane windows or storm windows, are specifically engineered to withstand high winds, flying debris, and forced entry. Unlike standard windows, they are constructed with multiple layers of glass bonded together with a resilient interlayer, typically made of polyvinyl butyral (PVB) or SentryGlas®. This interlayer acts as a shock absorber, preventing the glass from shattering and creating a dangerous opening in your home’s envelope.

When struck by an object, the outer layer of glass may crack, but the interlayer holds the glass fragments together, maintaining the window’s integrity and preventing penetration. This crucial feature distinguishes impact-resistant windows from regular windows, which typically shatter upon impact, leaving your home vulnerable to the elements and potential intruders.

Key Components of Impact Resistant Windows

Understanding the components of impact-resistant windows is essential for appreciating their superior performance:

  • Glass Layers: These windows typically consist of two or more layers of tempered or laminated glass, each contributing to the overall strength and impact resistance.
  • Interlayer: The interlayer, usually PVB or SentryGlas®, is the heart of the impact-resistant technology. It’s a flexible, durable material that bonds the glass layers together and absorbs impact energy.
  • Frame: The frame is equally important as the glass. It’s designed to securely hold the glass layers and withstand high winds and pressure. Common frame materials include aluminum, vinyl, and fiberglass.
  • Reinforcements: Some impact-resistant windows incorporate additional reinforcements, such as metal bars or thicker frame profiles, for enhanced structural integrity.
