RV wall construction is an important factor in selecting an RV. Each type of construction has its own advantages and disadvantages, such as cost, weight, insulation and weather resistance.
Knowing the different types of wall construction can help owners make an informed decision about the type of RV that best suits their needs and budget.
Let’s take a look at the different types of RV wall construction.
How are mobile home walls constructed?
The construction of mobile home walls can vary depending on the type and construction of the mobile home. The general process begins with the construction of the frame and the application of insulation. The walls are then lined on the outside and inside before all seams are sealed to prevent water penetration.
Knowing the materials used to build your walls can help you understand how to maintain and care for your RV. In addition, this information can be helpful when you hang items.
It is important to know that the specific process for building RV walls can vary by manufacturer and type of RV. Since many manufacturers use different techniques and materials, we recommend that you contact the manufacturer for the most accurate information for your specific unit.
How thick are the studs in mobile home walls?
The thickness of studs in RV walls can vary depending on the design and model. However, in most RVs, studs are typically made of wood, aluminum or steel and are usually between 1 and 3 inches thick.
If you need more information about the size and thickness of the studs in your RV walls, you can check the RV manual or contact the manufacturer.
Pay attention to the length of the screws you use inside your RV. A woman screwed the TV mount completely through the wall of her RV. Oops!
Types of mobile home wall construction
Manufacturers use different types of RV wall construction. Which one you use can have a significant impact on the capabilities of your RV and your comfort inside it. Let’s take a look at some of the most common types.
Aluminum frame with fiberglass exterior
This is one of the most common types of mobile home walls. It uses an aluminum frame with fiberglass panels. Manufacturers build the structure, apply insulation, and then attach the exterior panels with adhesive and screws. The seams are then sealed to prevent water from entering the wall.
These are great because they are lightweight, strong and extremely durable. They also increase the insulation of the RV, making it easier to stay inside in any weather. It is the perfect balance of strength, durability and insulation.
Laminated composite
A laminated composite wall for RVs uses a wood or aluminum frame to support the wall. After the frame is completed, the manufacturer applies several layers of foam or fiberglass insulation. The more layers, the more thermal and sound insulation the camper gets.
Once the insulation is complete, an outer skin of fiberglass, aluminum or other materials is bonded to the frame. An adhesive or vacuum technique creates a permanent, tight seal between the layers.
The final step is to apply the interior wall sheathing, usually wood or vinyl. This is attached with adhesive or fasteners. The finished product is a wall resistant to weather and moisture.

Steel frame with aluminum or fiberglass outer wall
Steel frame structures are a strong and durable way to build mobile home walls. However, they can be heavy and provide a different level of insulation than other types of construction. The frame is made of steel and is attached before foam or fiberglass insulation is added.
Manufacturers then attach the exterior wall panels, which are usually made of aluminum or fiberglass. The panels are attached to the frame with adhesive, screws or rivets. However, manufacturers must seal the seams and holes to prevent future water damage.
Solid fiberglass
Fiberglass mobile home walls are made of a single molded fiberglass shell that is strong, durable and provides excellent insulation. Unfortunately, fiberglass walls can be expensive and are more difficult to repair than other types.
The process begins with the manufacturer building a mold, usually of wood or aluminum. The manufacturer then covers the mold with layers of fiberglass, either by hand or with a resin that bonds the layers together. The mold is heated to allow the glass fibers to cure, which can take several hours.
Once the mold has cured, the structure is removed from the mold. The structure is then completed with trim pieces and decorative elements. The end result is a high quality mobile home that is strong, durable and well insulated.
Wooden frame with aluminum or fiberglass outer skin.
Wood frame mobile home wall construction consists of a wood frame covered with plywood or other materials. This type of construction is lightweight and inexpensive, but may provide a different level of insulation than others and may rot or cause other damage over time.
Wood frame construction is lightweight and relatively inexpensive, which can reduce the cost of the RV. Aluminum or fiberglass exterior walls do not weigh much, which can help improve fuel efficiency and reduce overall weight.

Why will mobile home walls peel?
When mobile home walls delaminate, the material of the exterior wall separates from the interior structure. This can happen for a variety of reasons. The most common reasons are water damage, poor construction, prolonged exposure to heat and sun, or damage from an impact.
If you want to avoid delamination in your RV, you need to maintain it regularly. Failure to do so can cause serious and expensive damage to your RV. Delamination repair is neither cheap nor easy.
The construction of the wall of the mobile home is important
The type of RV wall construction is an important factor to consider when purchasing an RV. Different construction methods offer different advantages and disadvantages, such as strength, durability, insulation and cost.
Regardless of the type of construction, however, it is important to properly maintain the RV. Take steps to prevent water damage, heat and sun exposure, or impact damage.
Regular inspections by a qualified RV technician can help identify and correct potential problems before they develop into serious issues.
