If you live in South Florida, the Gulf Coast, or anywhere along a hurricane corridor, you already know that choosing the right impact windows is one of the most important decisions you can make for your home. Two names come up more than almost any other in this conversation: PGT Innovations and CGI Windows & Doors. Both are respected manufacturers with decades of experience. Still, they are not the same, and depending on your home, your budget, and your priorities, one may be a significantly better fit than the other.
Let’s break it down honestly, the way a trusted neighbour would β no sales pitch, just real talk. PGT vs CGI
A Quick Look at Both Brands: PGT vs CGI

PGT Innovations has been manufacturing impact-resistant windows and doors since 1980, making it one of the oldest names in the business. Based in North Venice, Florida, the company built its reputation serving homeowners directly in the state most affected by hurricane activity. Over the decades, PGT has grown into a large family of brands, but its core product line remains focused on impact windows and doors for residential use.
CGI Windows & Doors is another Florida-born manufacturer, founded in 1992. CGI stands for “Custom Glass & Glazing Industries”, and the brand has earned a loyal following among builders, contractors, and homeowners who prioritize heavy-duty construction and custom sizing. CGI products are especially popular in high-end residential and commercial projects where performance standards are non-negotiable.
Both brands are Florida Product Approved and meet Miami-Dade County Notice of Acceptance (NOA) standards β the toughest building code requirements in the country. So right off the bat, you know you’re comparing two solid options.
Impact Protection: Too Close to Call
When it comes to the core job β keeping your family safe during a storm β both PGT and CGI deliver. Their products use laminated safety glass bonded to a durable interlayer that holds the glass together even when it shatters on impact. Neither brand is going to let a Category 4 storm walk through your windows.
Where they differ slightly is in frame construction. CGI windows are known for their heavy-duty aluminum frames, which many contractors describe as feeling exceptionally solid and well-built. PGT also uses high-quality aluminum, but they’ve invested more heavily in their vinyl and hybrid frame options, giving homeowners more material choices.
If raw structural strength and frame weight are your priority, many installers give a slight edge to CGI. If you want more flexibility in frame material and style, PGT has more to offer.
Energy Efficiency
Both brands offer Low-E glass options that reduce heat transfer and help keep your cooling costs down β a big deal in Florida where air conditioning runs nearly year-round.
PGT has put significant focus on energy efficiency across its product lines. Their WinGuard series, for example, is ENERGY STAR certified and designed to perform well in the demanding Florida climate. CGI also meets energy efficiency standards, but their product identity leans more toward structural performance than energy marketing.
For homeowners who are particularly focused on lowering utility bills or qualifying for energy efficiency tax credits, PGT’s lineup may give you more clearly labeled, certifiable options to choose from
Customization and Style

Here’s where personal preference starts to matter a lot. PGT offers an extensive range of window styles β single-hung, double-hung, casement, sliding, picture windows, and more β along with multiple frame colors and glass tint options. If you’re trying to match a specific architectural style or you want a polished, curated look, PGT gives you plenty of tools to get there.
CGI is also available in a range of styles and custom sizes, and they genuinely shine when it comes to large or non-standard openings. Their ability to produce oversized units with heavy-duty performance is one reason luxury builders and commercial contractors keep coming back to them. If you have large glass areas, floor-to-ceiling windows, or uniquely sized openings, CGI is worth a serious look.
Pricing
Neither PGT nor CGI is a budget brand β and honestly, with impact windows, you don’t want to cut corners. That said, CGI windows tend to run slightly higher in cost, largely because of their heavier construction and custom capabilities. PGT offers competitive pricing across a wider range of products, making it easier to find an option that fits different budget levels without sacrificing protection.
Keep in mind that the total cost of your project depends heavily on installation, the number of openings, and your specific window sizes. The brand price difference may be smaller than you think once everything is factored in.
Warranty and Support
PGT offers a limited lifetime warranty on their impact windows, which covers frames and glass under normal use conditions. CGI also offers strong warranty coverage. In both cases, proper professional installation is key to keeping your warranty valid β which is another reason to choose an experienced window and door replacement company rather than attempting a DIY job.
So, Which Brand Actually Wins?
Here’s the honest answer: it depends on your home and your priorities.
- Choose CGI if you have a larger, high-end home, oversized openings, or you want the heaviest frame construction available. CGI is a contractor’s brand that earns its reputation in demanding conditions.
- Choose PGT if you want more style options, a strong energy efficiency focus, and flexible pricing across a wider product range. PGT is a proven workhorse brand that has protected Florida homes for over 40 years.
Both brands will protect your home. Both are trusted. Both are Florida-proven.
What matters most is working with a knowledgeable window and door replacement company that can assess your specific home, explain your options clearly, and install your windows correctly β because even the best impact window in the world is only as good as its installation.
