At Harborside Marine Canvas and Upholstery, we specialize in custom Isinglass panel fabrication, installation, and replacement for boaters who demand comfort, function, and clarity on the water.

What Is Isinglass?

Isinglass is a marine-grade, flexible clear vinyl used in boat enclosures and panel systems. It's designed to provide visibility and weather protection while being lightweight and durable. Over time, exposure to UV rays, saltwater, and temperature swings can cause Isinglass to yellow, crack, or fog.

That’s where we come in. We specialize in:

FAQs – Isinglass Panels & Boat Enclosures

  • What’s the difference between Isinglass and Strataglass?

    Isinglass is the general term for clear vinyl; Strataglass® is a brand of coated Isinglass that’s more scratch-resistant, UV-stable, and distortion-free. It’s ideal for boaters seeking premium clarity and durability.

  • How long does Isinglass last?

    With proper care, Isinglass can last 2–5 years, while coated versions like Strataglass may last longer. Exposure, cleaning habits, and storage all impact longevity.

  • Can I replace just one panel?

    Yes — we can replace individual Isinglass panels while matching the size, material, and connection type. We’ll inspect to ensure full compatibility with your existing enclosure.

  • Can Isinglass be cleaned or restored?

    Minor fogging or debris can be cleaned using marine-safe products. However, once vinyl is scratched, yellowed, or cracked, replacement is the safest and best-looking option.

  • Do you offer rigid enclosures?

    Yes. For select projects, we also fabricate rigid acrylic or polycarbonate panels. These require different mounting systems and are quoted case by case.
