About Seaglaze

A leading manufacturer in the marine industry.

Marine Experts

Founded in 1970 by two families, Seaglaze still remains a family business to this day.

Seaglaze now occupies a modern, custom-built 10,000 sq ft factory on the outskirts of Norwich (UK).

Employing nearly 40 full time staff dedicated to the manufacture of high quality, affordable products, Seaglaze has a regular client list of prestige boat builders as well as private individuals, throughout the UK and abroad.

Seaglaze specialises in the design and manufacture of repeat boat windows, doors and hatch sets to the boat building industry. However, we are also very proud of our ability to work with anyone ranging from a private customer needing a one-off window to modern commercial vessels needing a full window, door and hatch package.

With our extensive range of custom extrusions coupled with the experience gained from 50 years in the industry, there is virtually nothing that Seaglaze cannot design and manufacture to a high standard and in a timely fashion.

At Seaglaze, we have invested a great deal in making sure our design and production staff are operating with the most modern equipment possible, be it from our ability to offer designs using the latest 3D technology or our custom built IT system from which the whole company is run.

  • Made to Order in the UK

  • One offs to entire sets

  • All products are made by hand

Very pleased with the quality of manufacture and product finish. They look very smart and despite some extraordinarily heavy and persistent rain there are no leaks!

Richard Llewellyn, Moody Owner

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.

Thea Lehner, Dutch Barge Owner

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