Quartz Luxury Windows & Doors

Quartz™ luxury windows & doors are architecturally engineered with a distinguished aesthetic design by Quaker Windows. Windows and doors make up a large part of a luxury home’s building façade, and Quartz™ was designed to present your home with distinction, both inside and out.

The largest of sashes. The most breathtaking views. The most comfortable interiors. Quartz™ is everything you would expect in high-end architectural fenestration. In the Quartz™ luxury product line, every component matters. And our patented manufacturing processes ensure that your windows will be both beautiful and strong.

The Quartz™ luxury collection’s patented OptiCore® technology defines the next evolution in thermal, structural and sound transmission performance for windows, while allowing for application flexibility that is changing the face of architectural window design.

OptiCore® technology was previously exclusive to Quaker’s® commercial products. Now we’re proud to present OptiCore® to the Quartz™ product lines. The Quartz CityLine and TimberLine series of windows feature OptiCore® technology across their product lines.

OptiCore® technology features architecturally enhanced aluminum, which combined with an Azo-Core™ thermal barrier reaches some of the lowest emissivity levels (known as U-factor) available in a frame design. Our energy efficient triple glazed glass packages, together with OptiCore, create a comfy interior space even during the coldest weather. All CityLine and TimberLine windows exceed ENERGY STAR requirements in all 50 states.

Quartz™ luxury windows are designed and manufactured to make installation easier. Our windows arrive with an integral miter cut continuous nail fin built into the frame, which surrounds the whole unit. You do not have to worry about open gaps around the window, or uneven fins. Quaker® also offers a variety of receptor, sub-sill, and panning options for more intricate installations.
