Kolbe & Kolbe Foundation™ Series Windows

Foundation™ Series single hung windows will provide you with everything you have come to expect from a window, and more! The unique frame design provides rich, traditional styling previously unavailable in vinyl windows. Exterior glazing allows for interior detailing and long-lasting beauty, both inside and out. The overlapping glazing beads enhance the window's traditional appearance with softened radius edges. What's more, Foundation™ Series single hung windows have interior and exterior accessory grooves. These allow for the easy addition of accessories such as "J" channel, traditional brickmould and mull covers, which will finish your windows beautifully.
Foundation™ Series single hung windows are perfect for your home's unique window arrangements. Don't limit yourself to single windows. Choose twin or triple units. Combine single hungs with studio units for beautiful picture windows. Add transoms, radius or geometric windows above your single hungs for a dramatic look. Segment head single hung units offer another interesting possibility... express your style with an arched window!
The beauty of Foundation™ Series single hung windows is more than skin deep. Being constructed of vinyl, they are nearly worry-free. Frame and sash corners are fusion-welded for enhanced structural integrity. These corners cannot open up, meaning that they are sealed against air and water infiltration. Sloped sills encourage water run-off while also providing a traditional look not commonly found in vinyl windows. Multi-chambered uPVC extrusions provide superior weatherability, enhance the strength of these windows and create a thermal break for insulating value while reducing noise transmission from the outside.
A 1-¼ " prepunched nailing fin provides for easy installation and helps seal the window to the opening. a 1-¼ " setback makes it perfect for use with various exterior materials such as siding, stucco or brick. Along with dual weatherstripping, this full perimeter integral nailing fin helps serve as a wind and water shield for weathertight installations. Optional jamb extenders allow the windows to fit nearly any wall construction.
The trim sash design provides a large daylight opening for a beautiful, unobstructed view. What's more, Foundation™ Series single hung windows are outfitted with recessed tilt latches. This allows for tilting or complete removal of the operating sash - making cleaning your windows an easy task.

Several other features add to the beauty and convenience of Foundation™ Series single hung windows. The 7/8" insulating glass units are an optimum thickness for exceptional thermal performance. Half screens with fiberglass mesh attach easily on the exterior of the windows. A positive screen attachment secures the screen to the frame and allows for easy removal from the interior. The lock rail is internally metal reinforced and the frame includes a stainless steel constant force balance system to help provide trouble-free sash operation. Finally, the sweep lock on the sash matches the vinyl color and provides an elegant appearance.

Opt for beige or white windows. The color is actually part of the vinyl, so it can't flake or peel off and there will never be a need for refinishing. Enhance the view with either flat or contoured grilles-in-the-airspace. Choose the standard 7/8" insulating glass or ask for H°K glass - 7/8" LoE insulating glass with argon fill* and warm-edge spacers. Many other glazing options are also available.

Foundation™ Series single hung windows are the perfect choice for new construction applications where performance and value go hand-in-hand. Ideal for commercial projects and entry-level homes, these windows deliver beauty, energy efficiency and are very low maintenance.
