In 1995, Dasan Windows & Doors began business in Southern California primarily as a glass distributor. In 2007, Dasan began manufacturing windows and patio doors at a separate facility in Cerritos, California. They now produce Earthwise windows in California as a member of the Earthwise Group. This family-owned manufacturer has two overriding principles that guide their business practices. These are: 1) To provide products made with superior materials and workmanship, and 2) To offer custom fabrication and personalized service that meets or exceeds customer requirements. Dasan Windows & Doors manufactures Earthwise windows and patio doors for the residential replacement market. Their Earthwise product line is sold to dealers, and contractors servicing the Southern California region. As with all Earthwise Group Members, Dasan builds their Earthwise products specifically for optimum performance in the climate zone they service. In addition to their customization capabilities, Dasan is ready with an in-stock program of their most common sizes, configurations, and colors, which includes their popular bronze frame. According to Brandon Choi, owner, “Joining the Earthwise Group has been an exciting process for our company. We can take advantage of shared best practices, their continuous improvement model, the sustainable manufacturing effort, and more.”
