Diamond Sea Glaze

Pioneers in Marine Windows and Glass

Diamond Sea Glaze designs and manufactures custom windows, boat doors, deck hatches, and glass for customers around the world. Diamond Sea Glaze delivers what our customers demand: sleek, strong and secure closures. DSG closures have quality built in – so everything else stays out. Each order is manufactured separately from beginning to end in our 80,000 sq. ft. vertically integrated plant just outside Vancouver, Canada. We are one of a few closure manufacturers in the world that insists on processing it’s own glass so we can ensure optimum quality control.
