North Sea Cape Classic 30 window gasket replacement

[DLETF]

I am interested in replacing the sun-damaged windshield and sliding glass gaskets on our trawler. The windshield glass is etched with the words "TEMPERED GLASS" but I have not found any information about the glass or window manufacturer.
This North Sea Cape Classic 30 was built near Church Point, Nova Scotia in 2001.
I would appreciate any information or suggestions about replacing the gaskets.
Thanks

If the builder is still in business then I would ask them who made the windows. If not then are there any other markings on the window frames?
