Marine environments are unforgiving. Salt spray, UV exposure, constant vibration, and temperature extremes will expose every weakness in a poorly designed window system — and on a vessel, those weaknesses become safety issues, warranty claims, and costly rework.

If you manufacture boats and need glazing that performs as hard as your vessels do, explore our marine glazing solutions and see what purpose-built aluminium framing can do for your production.

Marine conditions that standard windows can’t handle

Standard architectural glazing is designed for buildings. Boats are a completely different challenge.

A vessel window faces a combination of stresses that off-the-shelf products were never engineered to withstand:

  • Continuous salt water exposure that corrodes inferior seals and frame alloys
  • Hull flexing and vibration that stress rigid frame joints over time
  • UV radiation that degrades unprotected glass coatings and sealing compounds
  • Rapid temperature shifts between cold northern waters and warm southern climates
  • Fogging and condensation on windscreens that reduce visibility at critical moments

When a window fails at sea, it is not just an inconvenience. It is a structural breach, a safety risk, and a significant repair cost for your customer. The glazing you specify reflects directly on the quality of your vessel.

Custom aluminium boat windows built for marine conditions eliminate these failure points before they happen. The right material selection, profile geometry, and glass specification make the difference between a window that lasts the lifetime of the vessel and one that needs replacing after a few seasons.

We have spent more than 40 years engineering glazing solutions for exactly these demands. We understand what marine conditions do to materials, and we design every component accordingly.

Engineered to fit your vessel, not the other way around

Every boat design is unique. Forcing a standard window into a custom hull creates compromises in fit, aesthetics, and long-term performance.

We manufacture custom marine glazing solutions that are designed around your specific vessel geometry and production requirements. Our capabilities include:

  • Openable and fixed window elements for all hull positions
  • Windscreens and side windows with precise profile fit
  • Roof windows and below-deck hull side windows
  • Heated glass to prevent fogging and freezing in cold-climate operation
  • Toughened and laminated safety glass meeting relevant marine standards
  • Bent aluminium profiles for curved vessel lines and modern design forms
  • Specialty glass coatings for UV protection and moisture resistance

We maintain a library of over 100 aluminium profile types. When your design requires something beyond that range, we develop new profiles in direct collaboration with your engineering team. No compromises, no workarounds.

Our glazing also supports small to medium production batches. We work with boat manufacturers who produce limited runs and bespoke vessels, not just high-volume lines. Minimum order quantities apply, but we are structured to serve focused, quality-driven production rather than mass output.

One advantage that boat builders consistently value is our early design involvement. We review your specifications before production begins and flag potential issues — gaps in sealing geometry, profile choices that create long-term maintenance problems, glass specifications that may underperform in your target market’s climate. Catching these details at the design stage saves significant cost and rework later.

Why European boat builders choose Framecomp

Choosing a glazing partner is a long-term decision. The supplier you work with affects your production schedule, your product quality, and your ability to support vessels already in the field.

Here is what we bring to that partnership:

  • Finnish manufacturing quality — all products are made in Finland under ISO 9001 quality standards, with rigorous material selection and final product testing
  • ISO 14001 environmental certification — relevant for boat builders operating in environmentally regulated markets
  • Over 40 years of industry experience — deep knowledge of what works in demanding marine, transport, and industrial applications
  • End-to-end service — from initial design consultation through production and delivery, we manage the full glazing scope
  • Spare parts and batch support — we support vessels already in service with consistent spare parts availability, protecting your customers’ long-term ownership experience
  • Flexible production — we accommodate the production rhythms of boat manufacturers, including smaller batch sizes that larger suppliers typically decline

We do not position ourselves as the lowest-cost option. We position ourselves as the right option for manufacturers who need glazing that performs reliably over the full service life of the vessel, backed by a partner who stays engaged after delivery.

For European boat builders in the Nordics, the Mediterranean, and Central Europe, that combination of durability, design support, and long-term partnership is what drives the decision to work with us.

Start your glazing project with a free consultation

The best time to involve a glazing specialist is before your design is finalised. Early collaboration means fewer surprises, better material choices, and a window system that integrates cleanly into your production process.

When you get in touch, here is what happens next:

  1. We review your vessel specifications and glazing requirements
  2. We identify the right profile types, glass specifications, and opening configurations for your application
  3. We flag any design details that could cause problems downstream and propose solutions
  4. We provide a clear proposal covering materials, production scope, and delivery

There is no obligation and no pressure. We are a B2B partner, and we build relationships on substance — not sales tactics.
