Nope! Once you have Simonton StormBreaker impact windows, you can skip the stress of boarding up before a storm. These windows are designed and tested to stand up to powerful winds and flying debris, keeping your home sealed and protected — even if the glass gets hit hard. Think of it like having a built-in shield for your home. The laminated glass stays in place, so you don’t have to rush to cover windows or worry about sudden storms. It’s year-round peace of mind and one less thing to worry about when hurricane season rolls around.
Absolutely! Every Simonton StormBreaker window we install is built with energy efficiency in mind. They feature insulated glass, advanced Low-E coatings, and tight-seal vinyl frames that help keep your home cooler in the summer and warmer in the winter — all while reducing your energy bills.
Beyond saving money, energy-efficient windows make your home more comfortable year-round by cutting down on heat, glare, and outside noise. It’s protection, performance, and peace of mind all in one smart investment for your family and your home.
Quality windows are designed to last decades — and with proper care, Simonton StormBreaker impact windows can easily last 30 years or more. Their vinyl frames are built to resist corrosion, warping, and fading, even in Florida’s hot, humid, and coastal conditions. Unlike standard windows that can weaken over time, impact-rated windows are engineered for long-term strength and performance. You’ll enjoy lasting beauty, energy efficiency, and protection for many years to come — without the constant maintenance or replacement worries.
Simonton’s Double Lifetime Warranty means your investment is protected for as long as you own your home — and even beyond that. The warranty covers the window materials, hardware, and insulating glass against defects for your lifetime, and it’s fully transferable to the next homeowner if you ever sell your home. That transfer adds real value to your property and gives future owners the same peace of mind you enjoyed. It’s Simonton’s way of standing behind their craftsmanship and ensuring your windows deliver long-term beauty, performance, and protection.
Yes — at Fortress Windows, we stand behind every installation we complete. In addition to the manufacturer’s product warranty, all of our window and door installations come with a Fortress Workmanship Warranty that protects against installation-related issues. Our crews are trained to meet and exceed Florida Building Code standards, ensuring your windows are installed securely, sealed properly, and built to last. If anything related to our installation ever needs attention, we’ll make it right — because your trust and peace of mind matter to us long after the job is done.
