Curved Glass & Marine Windows

Modern vessel design often includes curved surfaces, complex angles and large openings that cannot be covered with a standard flat glass panel. In these cases, a custom-made solution is required so that the glass follows the shape of the vessel with precision.

The curvature must be compatible with the frame, the supporting points and the installation method. Even a minor deviation in the radius or geometry can cause installation difficulties, uneven gaps or unwanted mechanical stress.

• Adaptation to the vessel’s geometry
• Accurate curvature radius
• Uniform fitting within the existing frame
• Clear visibility from the interior
• Seamless integration with the vessel’s design
• Compatibility with the installation system

The term marine windows covers different types of windows and glass panels used in cabins, bridges, side openings, passenger areas and navigation stations.

Each application has different requirements regarding visibility, size, thickness, curvature, fixing method and exposure to weather conditions. For this reason, every glass construction must be designed according to the position of the window and the vessel’s intended use.

Thermal glass bending makes it possible to shape glass into a specific curve and geometry. The process must be carried out under controlled conditions so that the glass panel acquires the required shape without unwanted distortion.

The success of the construction depends on the correct combination of design, templates, moulds, temperature, processing time and controlled cooling. The accuracy of the initial project measurements
is equally important.

Accurate measurement is a fundamental stage in the manufacturing of curved glass. Measuring only the height and width is not enough. The curvature, angles, available clearance, edges and the points at
which the glass will be supported or bonded must also be recorded.

When an existing glass panel is available, it can be used as a measurement reference only when it has not been distorted and accurately represents the original geometry. Otherwise, a new template must be created or the construction must be measured directly on site.

• Recording of external dimensions
• Measurement of curvature radius and depth
• Inspection of the construction’s symmetry
• Recording of edges, holes and cut-outs
• Inspection of the available installation clearance
• Identification of supporting points
• Inspection of the existing frame
• Trial verification of the template

The material and glass thickness are selected according to the position of the panel, its dimensions, curvature, installation system and the stresses to which it will be exposed.

Different forms of safety glass may be used in marine applications, depending on the technical requirements of each project. The final selection must be made after evaluating the construction rather
than being based solely on appearance.

Each project is organised according to the vessel’s design, the type of glass panel and the method that will be used for its final installation.

1. 01

   Technical Assessment

   The position, geometry, dimensions and operating conditions of the glass panel are evaluated.

2. 02

   Measurement and Templating

   The perimeter, curvature, edges and special features of the construction are accurately recorded.

3. 03

   Selection of the Appropriate Glass

   The glass type, thickness and technical characteristics are determined according to the project requirements.

4. 04

   Mould Construction

   A suitable forming base is created to define the final curvature of the glass panel.

5. 05

   Thermal Glass Bending

   The glass is shaped under controlled conditions until it acquires the required geometry.

6. 06

   Final Processing

   The required processing of edges, surfaces and special features is completed.

7. 07

   Geometry Inspection

   The curvature, dimensions and compatibility with the project template are verified.

8. 08

   Installation Preparation

   The new glass is prepared for trial fitting, bonding and sealing.

More information about the complete process is available on our boat windshield and marine glass panel manufacturing page.

A correctly manufactured curved glass panel must be installed without being forced into an incorrect position or a distorted frame. The fitting must remain uniform around the entire perimeter
while maintaining the required installation clearance.

Adhesives, primers and sealing materials are selected according to the glass type, frame material and technical requirements of the construction.

• Trial fitting before bonding
• Inspection of uniform perimeter gaps
• Surface preparation and cleaning
• Use of compatible marine-grade adhesives
• Controlled alignment of the glass panel
• Continuous perimeter sealing

Our services cover new vessel constructions, refits and the replacement of older curved windshields or marine windows.

For replacement projects, the existing glass and frame are evaluated before the new panel is manufactured. When the original glass has become distorted or no longer fits correctly, it should not be copied without first inspecting the actual geometry of the construction.

• New windshields for private vessels
• Marine windows for commercial vessels
• Replacement of broken curved glass
• Reconstruction of older cabin windows
• Visual and functional upgrades
• Custom constructions based on templates
