Custom Window Systems: Wind-Pact Plus

This is one of the highest wind load rated products. It’s the only one of its type to be available in the 3-Lite Slider configuration at a reasonable price.  


It is also known as XOX or Slide-Picture-Slide, as well as Vinyl IMPACT Bypass, pocket door, and French-type hinged door. Custom Window Systems is definitely one of the most leading window innovators in USA (and right here in Florida!). The Wind-Pact windows are available in white, adobe, and bronze exterior with white interior.


Custom Window Systems has specifically chosen Cardinal Glass for their impact and high-performance heat reflecting properties. This is one of the highest performing glass products available. Cardinal Glass, one of the largest manufacturers of glass in USA, opened their 28th factory adjacent to the Custom factory in Ocala to be able to supply their needs.


Don't forget to ask us about the Cardinal NEAT Self Cleaning Glass! The future is here!


Custom remains the innovator in vinyl impact and energy efficiency. The others eventually must follow their lead! We have a special value package going on right now with all Wind-Pact Impact windows and doors.


Call us now and be surprised at how affordable vinyl impact or insulated windows and doors can be! Custom also manufactures one of the best basic aluminum windows in the marketplace. They are available in almost all configurations.

PGT Windows

Made in USA (Venice, FL), PGT is one of the oldest window manufacturers in the state of Florida. They pretty much invented the original IMPACT Windows, back in the early 90s after Hurricane Andrew devastated much of the Southeast Florida area. They have an extensive variety of products to select from, including Sliding Glass Doors. PGT Aluminum products are available in white and bronze colors, with some items also available in gray. Their vinyl products are made in white as well as tan.

They are the makers of StormBreaker Plus Windows. Made in USA (factories in several locations), StormBreaker Plus was one of the first impact vinyl tilt-in products available. Simonton windows are also available in a horizontal slider version. This brand is heavily advertised and is well known throughout Florida for protecting homes from past major storms. Simonton also produces a fine line of nonimpact windows and doors. They are available in white and tan colors.
