The Quartz™ luxury collection offers a variety of glass packages designed specifically to reduce the amount of sound transmitted through your windows by up to 25%, creating a more comfortable and healthier environment for you and your family.

Ease of Installation

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, subsill and panning options for more intricate installations.

The series can be easily factory-mulled or set up as a multiple unit in one continuous master frame. This immediately adds value in the form of ease of installation and less costly field labor.
