FABRICATION GUIDE

Standard Duty
The standard duty line of fixed windows is designed for applications requiring small size and light glazing. The most common application for these windows are lower cabin, aft bulkhead, and pilot or wheelhouse’s. These windows are commonly used for small commercial and recreational passenger vessels, ranging from small to medium sized river tugs, patrol boats, pilot vessels and pleasure crafts up to 30 feet in length. They are also used on tour vessels and inland ferries. They are available in mitered or radius corner styles.
The Standard duty line of sliding windows is designed for applications requiring less than 7 square feet of window area. These windows provide maximum ventilation when open, and become weathertight when closed. They can be fabricated in mitered or radius corner styles and are also available with optional screens and interior finish rings. See ordering information for available shapes and design considerations.

Medium Duty
The medium duty line of fixed windows is similar to the standard duty line of windows but designed to meet more demanding applications. The heavier frames permit glazing up to 3/8″ allowing these windows to withstand some of the toughest ocean going conditions. They are intended for use on larger commercial vessels and large luxury motor yachts. They are available in mitered or radius corner styles.
The medium duty line of sliding windows is designed for applications requiring greater window area and/or increased strength for larger vessels 30 feet and over. The heavier gage dual track sliding windows are also commonly used on large motor yachts, government and commercial vessels. They provide maximum ventilation when open, and become weather tight when closed. Heavy duty, self locking lock system provides for a strong secure close in the locked position. Specially located flip locks mounted on the inside sill secures the sliders in the open position. They can be fabricated in mitered or radius corner styles and are available with optional screens and interior finish rings. See ordering information for available shapes and design considerations.

Heavy Duty
The heavy duty line of fixed windows is our strongest and most durable extruded aluminum window. They are designed to meet the most demanding applications in any marine environment. From the north sea to the Antarctic oceans the heavy duty line has proven its superiority over other windows in its class. These heavy gage aluminum bolt-on series of windows are commonly used on the larger trans ocean vessels. They are available in mitered or radius corner styles.
The heavy duty line of our three track horizontal sliding windows are commonly used on large motor yachts for large cabin or salon side windows. These windows can only be used in applications where the bulkhead is greater than 2 inches in thickness. These windows come standard with a bolt on, self finishing trim ring that is part of the basic window structure. See ordering information for available shapes and design considerations.

Glazing
There are three basic types of glazing. A) Fixed/Opening windows, B) sliding windows, C) welded/mechanical windshields, D) curved / welded windshields. There are variety of different glazing options available for each style of windows and windshields.
To better understand these options, please refer to the glass tints and options below. For additional information on specific glazing for a certain style, please refer to the corresponding site. Also see windshield fabrication and options for glazing information.

Trim Rings
Trim rings are available in a variety of sizes and thickness. They are also available in many leg depths. Trim rings (or finish rings as they are sometimes referred to ) provide for a finished interior look. In the heavy duty line of windows, interior finish rings and/or aesthetics are usually not a high priority for large ocean going vessels.
Therefore, the self-finishing, through bolted backing plate is sufficient for these applications. Upon request additional finish rings can be custom made for the heavy duty line of windows.

When ordering trim rings, the depth of the legs and wall thickness in critical to insure proper fitting and alignment. Spigot wall thickness commonly ranges from 1/16″ to ¼”, (1/8″ standard). The legs usually range from 3/8″ to 2″, (1″ standard). Unlike bolt or clamp-on windows, trim ring mounting holes are drilled off-point from the holes in the window frames, allowing the finishing screws to be driven from both sides of the cabin wall. These holes are commonly sized for #8 screws. If the requested application calls for through-bolt type windows, the holes are drilled on-point ( in-line) with the holes of the window frame.

Screens
Ocean Dynamics USA manufactures screens that are constructed of marine aluminum extrusion for added strength and longevity. The framing can be finished in the same finishes available as the windows. The screen mesh is available in black and gray.
In two track sliding windows, the screens are commonly installed in the outside track adjacent (AFT) to the forward (stationary) glass. Since both the screen and the fixed glass are in the same track, the screen cannot slide. In three track sliding windows, the screen is usually installed in its own independent track, allowing it to slide freely.

Locks / Knobs
Lock system (A-400) :
Ocean Dynamics USA has designed a very unique and practical type locking system for sliding windows. Unlike other standard sliding windows, our lock system offers a strong spring loaded, 3 pc., interlocking unit which safely secures the sliding lite to the vertical frame post. See accessory page for additional information.

Knob pulls (H-714):
Depending on the height and weight of the sliding glass lite, knob pulls can be ordered and installed in a “hands friendly” area of the window, providing for better leverage when sliding an over sized glass lite.

Finishing
Before you select a finish understand why aluminum is the most desired metal for most marine window fabrication…. Why aluminum? More and more boat owners are having to replace the inferior windows on their boats with aluminum windows. Aluminum has a number of advantages over more costly materials such as Stainless steel or brass. It allows greater flexibility in design and requires less maintenance. For these reasons it is the most popular metal for manufacturing marine windows.
Although bare untreated aluminum has a relatively good corrosion resistance, it is not recommended for a marine environment. To improve their corrosion resistance and enhance appearance, aluminum windows are available in the following options:, ( see chart below)
