Wincore Windows & Doors
Wincore designed its 5400 Series vinyl windows for remodeling — welded frames, tilt-in sash and Low-E, argon-filled glass, positioned on value rather than luxury extras. RADIANT installs them across North DFW, and we’ll tell you honestly whether they fit your home and budget.
On display at our Southlake showroom — 500 N Kimball Ave #106, Southlake. Open the window, work the locks and compare it side by side before you decide.
Product lines
Wincore Windows & Doors is based in Parkersburg, West Virginia, and makes several vinyl window lines. Two are built for replacement work in existing homes; the rest are aimed at new construction or coastal codes.
“Designed for remodeling applications, 5400 windows offer value and performance.” Wincore’s own tagline for the line: “Don’t spend a fortune. Just make them think you did.”
Wincore calls the 7700 its “flagship retrofit product line,” with more decorative options than the 5400.
The 400 and 500 are new-construction lines with an integral nailing fin or brickmould. The 8400 (inland coastal) and 8800 (impact-resistant) are built for coastal building codes.
For replacing windows in an existing North DFW home, the 5400 and 7700 are the lines that matter.
Window styles
The 5400 covers the widest range of styles in Wincore’s lineup, which makes it easy to keep a whole house consistent — the hung windows in the bedrooms, a picture window in the living room and a bay off the breakfast nook.
White, Tan or Clay inside and out, with exterior laminate options Wincore lists as Hunter Green, Brown and Black.
Optional contoured grids sit inside the insulating glass, so the glass surface stays smooth to clean. Patterns: Colonial, Prairie and Perimeter.
Tinted bronze, tinted grey, obscure and rain glass are listed options — useful for bathrooms and street-facing rooms.
Energy & glass
In North Texas, the bigger job for a window is holding back summer sun, not winter cold. Here’s what Wincore builds into the 5400 — and the one detail worth checking on your quote.
Wincore says Low-E “helps keep homes warmer in winter and cooler in summer.” Its 5400 double-hung page lists Low-E with argon as standard; older literature calls it optional.
A ¾" dual-pane insulating glass unit with an argon gas fill, set ½" into the sash to keep the glass edges warmer.
Wincore says its U-channel spacer conducts less heat than conventional box spacers at the edge of the glass.
Wincore’s 5400 thermal performance chart shows ENERGY STAR status per style and glass package, zone by zone. Some configurations qualify in the South-Central and Southern zones and some don’t.
Ask us to show you the NFRC numbers for the exact window we’re quoting. In Texas sun, a lower solar heat gain (SHGC) number usually matters more than anything else on the label. On west-facing glass, solar screens block 80–90% of summer heat on top of that.
Warranty
Wincore’s Replacement Windows Warranty covers the 5400 and 7700. For the original homeowner living in the home, it lists lifetime coverage on the vinyl, hardware and screens against defects like peeling, blistering and corrosion; 20 years of full coverage on the insulating glass against seal failure that fogs the view, then a declining share for the 5400 after that; and 10 years on factory-applied exterior coatings. It transfers once to the next owner if Wincore is notified within 30 days (with a fee), and it does not cover labor. Wincore asks owners to activate the warranty within 30 days of installation. A separate 25-year glass breakage certificate exists for the 5400.
RADIANT reviews coverage with you at the estimate, so you know exactly what’s covered before you sign.
Honest fit
If your windows are foggy or cracked but the frames open, close and lock well, replacing just the glass may be all you need. We’ll tell you which windows need what.
A chambered vinyl frame with frames and sash welded at the mitered corners. Wincore says the chambers add strength, rigidity and thermal performance.
Both are Wincore replacement lines. The 5400 is positioned on value and performance. The 7700 is Wincore’s flagship retrofit line, with a beveled exterior frame that mimics wood and more decorative and color options. We can show you both and price them side by side.
It depends on the configuration. Wincore publishes a 5400 thermal performance chart showing ENERGY STAR status for each style and glass package in each climate zone; some qualify in the southern zones and some don’t. We’ll confirm the status of the exact windows on your quote.
Wincore’s replacement-window warranty lists lifetime coverage on vinyl, hardware and screens for the original owner, 20 years of full coverage on the insulating glass, and a one-time transfer to the next owner. Labor isn’t covered by Wincore. We walk through the details at your estimate. Read the warranty.
