Marine windows have different features depending on the type. Fixed windows are watertight for all vessels, while hinged marine windows are watertight with quadrants to allow for ventilation. Horizontal and vertical sliding windows allow for full visibility and the added convenience of opening and closing.
Marine windows come in a variety of shapes and sizes, and can be created according to custom specifications. Fixed marine windows are typically available as standard, medium or heavy-duty, and come in aluminum, steel or stainless steel. Hinged windows are available as bottom, top or side hinged and are suitable for use in any area that requires a watertight window that can open and close as needed. Horizontal and vertical sliding windows are popular on ferries and other various touring vessels, and come with singular or insulated glazing.
In the case of insulated glazing, two pieces of glass are spaced apart and sealed, which can reduce heat transmission by half. Users can add optional extras, such as insect screens or finish rings, and vertical design the sliding windows to be half-drop, half-raise or full-drop. Silicone or polyurethane are generally used for sealing. Water repelling felt, flock coated rubber or synthetic rubber are suitable choices for sliding windows.
