The Company
Commercial-Grade Frame Technology for Luxury Homes
The Quartz 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 Collection™. The Quartz CityLine and TimberLine series of windows feature OptiCore® technology across their product lines.
What is OptiCore?
Unparalleled Energy Efficiency
The OptiCore® frame design provides exceptional energy efficiency and thermal performance values that are unequalled in the industry.
A Difference You Can Feel
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. The EnergyEnhanced glass package, working together with OptiCore®, creates a comfy interior space even during the coldest weather. All CityLine and TimberLine windows exceed ENERGY STAR requirements in all 50 states.
Honoring Our Past
Founded by the husband-and-wife team of Bud and Marge Knoll in 1949, Quaker’s appetite for innovation has existed since our humble beginnings in the original Saint Louis shop. As time has passed, we’ve transformed to meet consumer demands, but our business philosophy has remained: be dedicated to detailed workmanship and provide a responsive service.
