Wincore Impact-Resistant Windows

​Wincore offers the StormForce 8800 Series, a line of impact-resistant windows specifically engineered for coastal regions prone to severe weather conditions. These windows are designed to withstand hurricane-force winds and the impact of flying debris, meeting stringent coastal building codes.

Key features of the Wincore StormForce 8800 Series includes the following:

  • Impact-resistant laminated glass — The 1-inch thick insulating glass unit incorporates a durable plastic interlayer bonded between two glass panes under heat and pressure. This construction ensures that, even if the glass is broken, the interlayer holds the fragments together, preventing penetration and maintaining the building's envelope integrity.
  • Robust frame construction — Frames and sashes are constructed from thick-walled vinyl profiles that are strategically reinforced and fusion-welded at precision-mitered corners. This design enhances structural strength and water-tightness, essential for withstanding extreme weather conditions.
  • Energy efficiency — Standard features include Low-E glass and argon gas fills, which improve thermal performance by reflecting heat and reducing heat transfer. The innovative U-channel spacer design further reduces heat loss and helps retain insulating gas, contributing to lower energy bills and increased indoor comfort.
  • Enhanced security and noise reduction — Laminated glass not only resists impacts from debris but also deters forced entry attempts and reduces external noise infiltration, providing a safer and more comfortable indoor environment.

The StormForce 8800 Series is available in various styles, including double hung, double slider, casement, awning, picture, and geometric shapes, allowing you to choose designs that best fit your aesthetic and functional needs.

Wincore Window Energy Efficiency

​Wincore emphasizes energy efficiency across its product lines, integrating advanced technologies and design features to enhance thermal performance and reduce energy consumption.

Key Wincore Energy Efficient Features

Wincore windows include the following energy efficiency features, providing you with the opportunity to save more on your utility bills while also increasing the comfort of your home:

  • Low-E glass — Wincore windows are equipped with Low-Emissivity (Low-E) glass coatings that minimize the amount of infrared and ultraviolet light passing through the glass without compromising visible light. This helps maintain indoor temperatures by reflecting heat back into the room during colder months and reducing heat gain during warmer months.​
  • Argon gas fill — The space between glass panes in Wincore's dual-pane windows is filled with Argon gas, an inert gas that enhances insulation by reducing heat transfer. This feature contributes to improved thermal performance and energy savings.​
  • U-channel spacer system — Wincore utilizes a uniquely designed U-channel spacer system that reduces temperature transference between glass panes. Unlike conventional box spacers, the U-channel design forces the transfer current to travel a longer path, thereby weakening the conduction of heat and improving the window's insulating properties.
  • Chambered vinyl profiles — Wincore window frames feature honeycombed chambers within the vinyl profiles, providing structural strength and acting as tiny pockets of insulation. These chambers enhance the overall energy efficiency of the windows by reducing heat flow through the frame.

Wincore ENERGY STAR® Partnership

As an ENERGY STAR® partner, Wincore offers products that meet or exceed the stringent energy efficiency guidelines set by the U.S. Environmental Protection Agency. Windows and doors bearing the ENERGY STAR label have undergone independent testing to ensure they contribute to reduced energy consumption and increased savings for homeowners.

Energy Efficiency Tax Credits

Homeowners who install ENERGY STAR certified windows and doors from Wincore may be eligible for federal tax credits under the Residential Energy Credit program. To qualify, the products must be installed in an existing primary residence and meet the specific requirements outlined by the IRS. It's advisable to consult a tax professional or visit the IRS website for detailed information on eligibility and the application process.

By integrating the energy efficient features listed above and maintaining partnerships with programs like ENERGY STAR, Wincore demonstrates a commitment to providing products that enhance home comfort while reducing environmental impact and energy costs.

Wincore Window Warranties

​Wincore offers comprehensive warranties for its window products, providing coverage for various components under specific terms and conditions. It’s important to note that warranty coverage may vary by window series; for this reason, it’s important to ascertain and understand your warranty terms before purchasing.

Wincore offers warranty coverage for the following window components:

  • Vinyl components — Wincore vinyl frames and sashes are warranted against peeling, flaking, chipping, blistering, and corrosion for the lifetime of the product. This lifetime warranty applies to the original purchaser as long as they reside in the home where the products were installed. It's important to note that this warranty becomes void if the vinyl is painted, stained, or altered in any way.
  • Insulated glass units — Wincore insulated glass units are covered under a 20-year limited warranty. If a defect arises within this period, Wincore will provide replacement parts at no charge. After 20 years, the warranty becomes pro-rated, meaning the coverage decreases over time. Additionally, Wincore offers a 25-year Glass Breakage Warranty for certain series, such as the 5400 Series, where the company will send a replacement insulated glass unit or sash at no charge if the glass breaks within 25 years from the date of purchase.
  • Hardware — Wincore hardware components, including locking mechanisms, fasteners, rollers, and balances, are warranted against peeling, flaking, blistering, rusting, and corrosion for the lifetime of the product. In the event of such defects, Wincore will provide replacement hardware at no charge.
  • Screens — Wincore window screens are covered under the company’s comprehensive warranty, ensuring they are free from defects in material and workmanship. If such defects occur, Wincore will provide replacement parts at no charge.

To activate your Wincore warranty, you’re required to complete the registration process within 30 days of installation. This can be done by mailing the perforated card found in the warranty pamphlet supplied by your Wincore supplier or by completing the online form available on Wincore's website.

Nationwide Supplier Network

Wincore’s window products are available nationwide through the company’s expansive supplier network. To find a supplier near you, you can initiate a search on the Wincore website. You’ll be required to fill out a form with your address and some other basic contact information. After submitting this information, you’ll receive supplier/builder recommendations based on your location.

The Bad

  • Warranty Limitations and Exclusions
  • No Specialty Windows

Warranty Limitations and Exclusions

Wincore warranties cover only manufacturing and material defects and do not include damages caused by improper installation, normal weathering, accidents, fire, flood, acts of God, vandalism, misuse, abuse, harmful chemicals, building settlement, or structural failures. Additionally, labor costs for removal or installation of replacement parts and shipping costs for returning defective products are not covered.

It’s also important to note that any window damage due to installation isn’t included in Wincore warranty coverage. In many cases, Wincore suppliers may offer workmanship warranty coverage, but you’ll have to confirm this with your specific supplier.

No Specialty Windows

While Wincore offers a variety of window customization options, including frame colors, grid options, etc., the company doesn’t offer any specialty window options, such as allowing you to customize your window shapes. For many customers, specialty window options aren’t necessary, as the common window styles available will meet most needs and preferences. However, if you’re looking for something very specific or unique, you may need to consider other window companies in your area.
