What are RV wall panels?

RV wall panels typically have three layers: an inner layer, an insulating layer and an outer layer that serves as the liner of the vehicle.  

The inner layer of most vehicles, which includes the walls and roofs, is composed of two different materials. Typically, medium-density fiberboard (MDF) or thin plywood is used to cover the walls of vehicles. Vinyl panels can also be found in more luxurious or expensive cars. In contrast, fiberglass-reinforced plastic panels are often used on car roofs, as they are lightweight, moisture-resistant and do not require painting.

Fiberglass wall and roof sheathing is also available, manufactured with a polyester resin system. This is a highly durable, gel-coated fiberglass composite panel with an ideal balance of UV-stabilized glass content for improved weather resistance. 

These panels are applied on vehicles, such as fifth wheels, camping trailers, motor homes and pick-up trucks on exterior walls, entrance doors and trunks.
