PGT vs CGI: What's the Difference?

If you are shopping for impact windows or doors in Florida, you’ve probably seen the names PGT and CGI tossed around. They’re both solid brands, but they aren’t the same. Choosing between them isn’t just a matter of picking a logo or price tag. It comes down to how the windows are built, how they handle storms and what works best for your home’s style and layout. Some people care more about durability. Others care about looks or energy efficiency. And yes, sometimes it’s just personal preference. Knowing the difference between PGT and CGI saves headaches, money and ensures your home is actually protected when the next storm hits.

PGT has been a household name in Florida for decades. These windows and doors are engineered to take a beating from Mother Nature.

• Durable Frames: Most PGT windows use high-grade aluminum or hybrid frames. They’re stiff, won’t warp and hold laminated glass like a champ.
• Laminated Glass: The glass is tough. It’s designed to flex but not break when hit with flying debris during hurricanes. That’s what really matters here.
• Energy Efficiency: Low-E coatings reflect the sun’s heat, keeping your home cooler and your AC from working overtime.
• Customization: PGT gives you choices. Frames, finishes, grilles and glass tints. You can make your home look exactly how you want.
• Track Record: Contractors love PGT because installations are predictable and warranties actually cover real problems.

Honestly, if you’re looking for reliability, PGT is hard to beat. It’s classic, proven and built for Florida storms without fuss.

CGI is another big name in impact-resistant windows and doors and they do things a little differently.

• Strong Laminated Glass: CGI uses reinforced vinyl or aluminum frames with laminated glass designed to withstand hurricane-force winds.
• Versatile Styles: They’ve got sliders, casements and French doors, all impact-rated. So whether you want a sleek modern look or a more traditional feel, there’s an option.
• Energy Efficiency: Heat-reflective coatings and UV protection keep rooms cool and prevent furniture from fading.
• Storm Performance: All CGI products meet Florida building codes for wind load and debris impact. No guessing here, these windows are tested.

CGI tends to appeal to homeowners who want strength and style without thinking too much about the frame material. It’s tough, practical and looks good doing it.
