The Importance of Installing the Suitable RV Interior Walls


As an RV is your second home, its quality will create a major impact on your living standard. As a result, every RV owner should be aware of the materials used to construct RV interior walls.

Since the interior walls are in charge of a variety of things, choosing the correct kind is vital. Before we go into the exact materials used to create inside walls, let’s take a look at why having these internal walls constructed in your motorhome is essential:

Providing adequate insulation

You can rely on your RV’s exterior panels to shelter you from the extreme high temperature of the wilderness. Interior walls of your RV offer the much-needed insulation, allowing it to be cooler inside on summer days and warmer in colder months.

For instance, if you plan to go RV camping in the winter, vinyl and other plastic products have better insulation than wood. Unless you are frequent summer campers, you might want to add more layers of thick wood board into interior walls for extra insulation as it is durable and easy to install

Offering soundproofing amenities

The inside walls act as a sound barrier between the outside and the inside. The solitude and quietness will be provided by a soundproof internal wall. You don’t want to be bothered by outside noises while parked in a prime location.

Furthermore, I believe you also don’t want anyone else to know what’s going on within the trailer. Hence, pay special attention to the materials used to construct RV interior walls to achieve this two-way soundproofing facility.

Additional soundproofing may be created by interior walls. Soundproofing is an option, but it is sometimes too costly. Instead, you might decide to do it later on the inside wall.

If you don’t want to rebuild the external wall, there are not too many soundproofing choices. However, you might go a step further and install sound prevention on top of your original insulation.

Improving aesthetics

Having an aesthetic design is the most popular reason for people to replace their motor home’s interior walls. While your RV may already have an internal wall, it may not be what you want. This is certainly true if your RV is outdated or the furniture does not fit your needs.

Renovating the RV interior will enable it to shine. If your RV’s interior is made of rusty metal, changing it into a more natural-looking hardwood surface is the best option. It is, after all, your trailer. Hence, you must customize it.

If you are not fond of the wooden design, you may easily replace it with a suitable wallpaper. However, wallpapers are not readily applied to all surfaces. They look best when placed on vinyl or laminated surfaces.

Different Types of Rv Interior Wall Materials


While you have determined to have your interior walls replaced, the difficult aspect now is deciding which type of wall paneling to utilize. There are different materials of RV walls to select that it may be difficult to know where to start.

Choosing the perfect model, on the other hand, will be a lot easier if you understand what to search for. Here are some examples of different kinds of walls you may use to decorate the motorhome’s interior.

Composite Plywood

RV manufacturers utilize a kind of plywood known as Composite Plywood for their RVs. Composite plywood is made up of many sheets of wood and appears in the shape of a big hardwood sheet.

The wood panels are glued one on top of one and another to give the wall its greatest strength. The inside layers of plywood trailer walls are made of inexpensive wood, while the outer layer is made of wood veneer.

Due to the design, Plywood RV interior walls are more common in mid- to high-priced camper vans.

In addition, RV interior walls made of plywood will usually be covered by paint, wallpaper or glue, so if you want to repaint the plywood walls or add more sheets of wood veneer, you may need to remove all of them.

Here are some advantages and disadvantages of plywood walls:

  • Pros
  • Durable structures: Plywood has the advantage of being solid and resistant to impact damage. It has a lot of compressive strength because it’s made up of many sheets squeezed together. It won’t readily shatter, bend, and dent if you strike it.
  • Natural appearance: In contrast to the polished yet chilly metal and plastic, the wood grain helps you feel cozy and comfortable. You can’t help but enjoy the warmth when you’re surrounded by actual wood walls, even if they’re in plywood form.
  • Cons
  • Weak waterproof ability: This type of RV wall often gets wet and suffers from water damage, which can turn into a big trouble. A leak on the roof might allow water to seep through. The adhesive will then degrade, causing the veneers to come free.
  • Vulnerable to fungi and mold: Mold, fungi, and other water-related issues will accompany the water damage. If somehow the plywood panels come into touch with water, fungus might form on the wall.
  • Take all possible precautions to keep the RV interior walls dry. If it becomes wet, clean it with a microfiber cloth right away. Use a blow dryer to deliver moderate heat to each area if feasible.


RV interior walls made of vinyl are extremely popular as they are affordable. Since vinyl sheets are simple to cut and install, you may save money on the cost of acquiring a professional service. RV walls made of vinyl sheets include adhesive on the backside, allowing you to adhere them to walls by simply peeling off the plastic layer.

  • Easy to cut and manipulate with versatile design: Cutting vinyl does not necessitate the use of any special equipment. All you’ll need is a sharp utility knife to get started.

  • Cos:
  • Weak durability: Vinyl has the disadvantage of becoming brittle over time. Vinyl is not trustworthy when seeking for a long-lasting substance. After a few years, vinyl interior wall borders may appear cracks. However, due to its cheap rate, you may change it at any moment.

MDF (Medium density fiberboard)

Medium Density Fiberboard (MDF) is a common plywood substitute. This is also a cost-effective alternative, however these boards will not last long. MDF is a type of wood that can be made into any shape or size with ease. MDF is made up of adhesive sawdust sandwiched between numerous sheets of hardwood.

  • Cost-effective: MDF can be bought at a cheap cost and simple to install in RVs.

  • Cons:
  • Lifespan: MDF is a short-term solution compared to many other RV wall materials. It can degrade with time because it’s constructed of glued sawdust.
