CASE STUDY: Evolution 30 Boat

Evolution Boats approached Seaglaze at the beginning of 2018 looking for a set of windows and doors for the new Evolution 30 vessel the company were building for a customer in France. We recommended the series 11 clamp-in frames for easy installation and adherence to ISO 12216.

Diane Ching, Evolution Boats Ltd

I am so impressed with how professional and smooth the process was. All of the crew involving changing the window had never had a window delivered on time before so getting 10 custom windows delivered on time is priceless! The windows were packed up well and looked better than I could have wished for.

Finally in, looking good, and most importantly….watertight.
