Expertly Designed Energy-Efficient Window Frames

Strong, Insulated Window Frames are Essential

T-Core Insulated Frames

Window frames have two important jobs: protecting all of the window’s other components, and tying the windows into the walls of your home. To do these jobs well, window frames need to be structurally strong and built for energy efficiency. Improveit’s Performax54 Windows feature the T-Core Insulated Frame to maximize both of these characteristics, creating a window frame that’s a whopping 400 times stronger than standard vinyl window frames.

Here’s how:

Virgin Vinyl vs Recycled Vinyl Windows

Virgin vinyl refers to vinyl material that has not been previously used in other applications. Unlike reground or recycled vinyl, which degrades after each use and re-processing, virgin vinyl offers exceptional strength and durability essential for windows to stand the test of time. Performax54 windows are made from a virgin vinyl blend to ensure you get long-lasting, high-performing window frames that won’t rot, fade, chip, or peel over time.

Fusion-Welded Window Frames

Just like the steel frames of skyscrapers, Performax54 windows’ feature fusion-welded frames. Mechanical fasteners can fail over time, making the sash, glass, and spacer components (as well as the frame itself) susceptible to breakage. Believe it or not, the welded seams in Performax54 window frames are actually stronger than the vinyl itself!

I-Beam Reinforced Windows

Performax54 window frames feature I-beam reinforcement for structural integrity form the inside out. This guarantees that the frames won’t warp, bow, or sag, and protects the sash and glass components from the effects of expansion, contraction, and settling. With I-beam reinforcement, Performax54 windows stay square, true, and securely installed.

Efficient Insulated Window Frames

Too often, window frames are overlooked as a factor in a window’s energy efficiency. Some manufacturers even leave their vinyl window frames hollow. This allows for wasteful conduction, or heat transfer, through your window frames. Whether your warm indoor air conducts to the cold exterior in the winter, or hot air conducts into your air-conditioned home in the summer, without insulated window frames, you’ll be paying more to heat and cool your home year-round. Performax54 windows feature T-Core Insulated window frames with spray foam insulation filling every nook and cranny. This application provides the air-tightness you need for the most energy-efficient window frames possible.
