Fortis Windows Seamlessly Combine State-of-the-Art Engineering with Elegant Design

Vytex proudly manufactures a wide selection of vinyl replacement windows, including the Fortis series, our mid-level option. Fortis windows provide the ideal combination of innovative engineering and stylish design, making them an excellent choice for homeowners throughout the country.

Innovative Engineering

We offer Fortis windows as our mid-level series, but they’re far from average. They are equipped with a number of state-of-the-art engineering components, including the following, that set them apart from other home windows on the market:

  • VyFoam™ insulation in the frame and sash for added insulation
  • A tight, mortise-cut sill dam wall for enhanced structural integrity and reduced air and water infiltration
  • An interlocking sill and sash for increased wind resistance

Fortis windows are so strong and durable that they’ve achieved an R50 performance grade, a rating that considers factors such as structural performance, resistance to air infiltration, and resistance to water penetration. In fact, they’ve even been demonstrated to stand up against a 171-mph wind load, making them 180 percent stronger than the minimum requirement for the industry.

Stylish & Customizable Design

It’s equally important to choose replacement windows that will beautifully complement the style of the home and reflect the homeowner’s personal tastes. Fortis windows feature thick VyFoam™  insulation, but the frames are anything but bulky — in fact, the Fortis series features one of the thinnest, most aesthetically pleasing frame designs available today.

Homeowners will also love Fortis windows because they can customize them to suit their personal preferences. They’ll be able to select from a wide variety of window styles, including bay, double hung, garden, hopper, picture, and sliding. They can also choose from various exterior colors, which are applied using our exclusive VyCoat™ exterior coating system. With regard to the window interiors, homeowners can choose between two interior colors (white or beige). And, they’ll be able to select from various window grid designs such as flat and contoured grids as well as custom options.

Had a contractor in NJ replace 17 windows using Vytex Windows in the spring. The windows are very strong and look high end. The new windows definitely helped with the drafts. Our old windows were original from 1987 and our home was freezing in the winter and hot as an oven in the summer. The new Vytex windows definitely got rid of the draft issue we had and the difference is very noticeable especially in the bedrooms. Next on our list is a new patio door from Vytex.

Very impressive facility and great customer service from Brooke Ratcliffe!

I am writing a nice review on my Vytex window experience. We are in new jersey and had all new windows installed about 10 months ago as well as a Vytex patio door. Our home was very drafty and made it very uncomfortable in the cold winter months and just as bad when it was hot in the summer. Our home is now much warmer and quite noticeable. The difference was equally noticeable this past summer when we had a heat wave; our home was much cooler...
