Purpose and fitment for Mercedes Vito W639

The described window is designed for installation in the rear, right section of the Mercedes Vito W639 body, in the rear door area. The vehicle placement is defined as rear – right side, which facilitates clear identification of the part when planning repairs or replacements. Thanks to a design consistent with factory body specifications, the glass works with original seals, guides, and door opening mechanisms, which promotes stable seating and reduces the risk of leaks.

AS3 glass characteristics and heat-insulating properties

The use of AS3-grade glass means that the component meets the safety and light transmission requirements for windows installed in the rear zone of a vehicle. The heat-insulating construction helps reduce interior heating, especially in the cargo or passenger area, which is important for both comfort and the protection of transported items.

The black finish of the glass helps reduce glare and improves privacy inside the vehicle. In practice, this translates into:

• reduced penetration of sunlight into the rear part of the body,
• more uniform thermal conditions in the cabin or cargo area,
• a cohesive, aesthetic appearance of the side and rear body sections.

Performance parameters and installation benefits

As a component from the Car windows group, the product has been prepared for stable installation in factory mounting points. The appropriately selected shape and edge profile facilitate service work, and a correctly seated window supports the maintenance of body tightness and proper structural rigidity in the rear door area.

Key benefits of using this window in a Mercedes Vito W639 include:

• restoration of full functionality to the rear right door zone after damage to the previous element,
• maintenance of compliance with the factory body line and glazing characteristics,
• improved thermal comfort thanks to the heat-insulating properties of the glass.

Color scheme and body integration

The black color of the glass promotes a harmonious connection with factory seals, frames, and trim elements of the rear body section. This type of finish is particularly beneficial in commercial and passenger-delivery vehicles, where it is important to limit the visibility of cargo and maintain a uniform style of side glazing. The dark, heat-insulating glass also helps reduce the effect of interior overheating when parked in sunny locations.

Condition of the element and practical aspects

The product is offered as a used part, which allows for economical repair of the rear body zone while maintaining the functionality required for daily operation. Choosing a used window is often a beneficial solution for fleet or heavily used vehicles, where a reasonable balance between repair costs and vehicle value is important. During installation, it is recommended to use the services of a workshop experienced in working with glass body elements to ensure proper sealing and durable mounting of the window.
