Everything you need to know about materials for interior walls in RVs

Important things to think about before purchasing interior wall material for RVs

When renovating the interior of a pre-owned RV, the insulation, walls, and ceiling likely need some TLC. There are a lot of dings and scratches on the walls. The window and door seals and seams may have deteriorated if the RV has been parked for an extended amount of time, enabling moisture to enter and the growth of mold and mildew.

When purchasing new wall panels for RV material, it's critical to take into account two crucial product qualities to handle these two problems and ensure that your redesign will last the test of time:

Resilience. RV walls sometimes sustain damage from objects dropping off them in transit and people knocking into them while navigating the cramped interior. An optimal choice for RV wall cladding should withstand impact and touch. 

Water and moisture resistance. RV owners most frequently need to rebuild the inside walls and ceilings because of water damage and mold development. It's also an issue that must be resolved immediately, since failing to do so may necessitate replacing more than just the paneling. 

Which interior wall material is the most common in RVs? 

RV walls typically consist of three layers: an internal layer, an insulating layer, and an exterior layer that forms the shell of the vehicle.  

The inside layer of most RVs, which consists of the walls and ceilings, comprises two distinct materials. Medium-density fiberboard (MDF) or thin plywood is typically used to cover the walls of RVs. Higher-end or more costly campers could also include vinyl paneling. Meanwhile, PVC or fiberglass reinforced plastic (FRP) wall panels are commonly seen on RV ceilings since they are both moisture-resistant, lightweight, and don't require painting. 

There are a few advantages and disadvantages to each material to consider, regardless of whether you decide to use two distinct materials for your RV's walls and ceilings or would rather furnish the entire area with one product.
