Lightweight Camper Panels: Diy Guide To Building Your Own

how to make light weight camper panels

Building a camper is a fun and rewarding project, but it's important to keep weight in mind. Here are some tips for making lightweight camper panels:

- Use lightweight materials such as composite panels, foam, or lightweight plywood for the walls and roof. Composite panels, such as those made with epoxy-fiberglass and polystyrene foam, are much lighter than plywood and won't rot if exposed to moisture.

- Consider using a lightweight alternative to timber for the floor and body, such as ThermHex polypropylene honeycomb core material, which is up to 80% lighter than plywood.

- Opt for lightweight batteries, such as lithium batteries instead of AGM batteries, to reduce weight.

- Choose lightweight framing options, such as 8020 instead of wood, to cut down on weight.

- Use lightweight wall panels, such as Duotex, which is easy to install and gives a finished look without adding unnecessary weight.

- Be mindful of the weight of appliances and fixtures, and opt for lightweight alternatives where possible.

Using foam as a base for your panels

Choosing the Right Foam

First, you'll need to select the type of foam you want to use. There are several options available, including rigid foam insulation, polystyrene foam, and polypropylene honeycomb core material, like ThermHex. Consider the specific requirements of your project and choose a foam that best suits your needs in terms of weight, strength, and insulation.

Planning and Preparation

Before you begin constructing your panels, it's important to have a clear plan and gather the necessary tools and materials. Decide on the size and shape of your panels, taking into account the dimensions of your camper. You'll also need to determine the thickness of your foam and choose an appropriate adhesive, such as glue or epoxy, to attach the foam to your panel base.

Constructing the Panels

Once you have your materials ready, you can start building your panels. Here are some general steps to follow:

  • Cut the foam to the desired size and shape using tools such as a fine-tooth saw, a rasp, or a utility knife.
  • Join the foam pieces together using an adhesive like glue or epoxy. Ensure that your work area is well-ventilated during this process.
  • If you're creating "poor man's fiberglass," drape the foam with a material that has tensile strength, such as canvas or window screen. Secure it in place with more adhesive.
  • Sand and paint your panels as needed to achieve the desired finish.

Tips and Tricks

  • When working with adhesives, always work quickly as they tend to set fast.
  • Consider using a combination of different materials for your panels, such as foam for insulation and wood for structural support.
  • If you're creating curved shapes, foam can be easily shaped to fit your design.
  • For added strength and stability, consider using a sandwich panel construction with a foam core and facings such as aluminium or plywood.

Opting for composite panels

Composite panels are made from a variety of materials, including fibreglass, epoxy-fiberglass, polystyrene foam, and ultra-high molecular weight polyethylene plastic. These materials are sandwiched together to create a strong, lightweight, and often more affordable structure than traditional building materials.

The benefits of composite panels include:

  • Lighter weight than aluminium panels, with better impact resistance and repairability.
  • Greater strength and waterproofing than wood.
  • Excellent thermal insulation.
  • Ease of cleaning.
  • Resistance to corrosion and mould.
  • Smooth surface finish.

Composite panels are ideal for various applications in camper van construction, including side walls, floors, roofs, and front and rear panels. They can also be used for structural components, ramp doors, decking, and slide-outs.

When opting for composite panels, you can choose from a range of core materials, including:

  • XPS (Extruded Polystyrene) Foam: A popular choice for RV wall panels due to its smooth, uniform surface and relatively high compressive strength.
  • PET (Polyethylene Terephthalate) Foam: A closed-cell thermoplastic structural foam with good shear and compressive strength.
  • PU (Polyurethane) Foam: Offers excellent thermal insulation and highly compressed stability.
  • PVC (Polyvinyl Chloride) Foam: Simple, inexpensive, and easy to process, making it a good option for RV wall panels.

In addition to the core material, you can also choose from different skin materials, such as fibreglass-reinforced plastic or continuous fibre-reinforced thermoplastic.

Composite panels are available in various sizes and thicknesses to suit your specific needs. They can be purchased as pre-manufactured panels or custom-made to your requirements. Some suppliers also offer CNC cutting services to ensure precise and efficient panel fabrication.

By opting for composite panels, you can create a camper van that is strong, durable, lightweight, and well-insulated, making your camping experiences more enjoyable and comfortable.

Using plywood for your panels

Plywood is a great option for building camper panels, as it is strong, lightweight, and easy to work with. When choosing plywood for your camper panels, it is important to select a high-quality product that will withstand the rigors of camping and outdoor use. Here are some tips and instructions for using plywood for your camper panels:

Selecting the Right Plywood:

  • Choose a plywood product specifically designed for RV and camper construction, such as T-PLY plywood, which offers superior surfaces and consistent cores for enhanced fastener-holding strength.
  • Consider the thickness of the plywood. Camper panels typically range from 3/8" to 1" in thickness, so select a product that falls within this range.
  • Look for plywood with a smooth, premium-grade surface. This will not only give your camper a sleek appearance but also make it easier to apply paint or other finishes.
  • Opt for plywood with a tongue-and-groove or square-edge profile. This will ensure a tight fit between panels and reduce the need for extensive sanding or trimming.

Preparing the Plywood:

  • Before beginning construction, make sure you have all the necessary tools and materials, including plywood sheets, a table saw or circular saw, measuring tape, a drill, screws or nails, wood glue, and sandpaper.
  • Cut the plywood sheets to the desired size and shape using a table saw or circular saw. Mark the cutting lines with a pencil and straight edge to ensure straight and accurate cuts.
  • If you need to join two pieces of plywood together, use a strong wood glue and clamps to create a solid bond. Let the glue dry completely before moving on to the next step.
  • Sand the edges and surfaces of the plywood to smooth out any rough spots and create a uniform finish. Pay extra attention to the areas where panels will join together to ensure a tight fit.

Assembling the Camper Panels:

  • Start by creating a framework for your camper using wood studs or metal tubing. This framework will provide structural support for your plywood panels.
  • Attach the plywood panels to the framework using screws or nails. Place the screws or nails along the edges of the panels and into the studs or tubing below.
  • Ensure that the panels are flush with each other and that there are no gaps between them. Use wood filler or caulk to fill any small cracks or seams.
  • If desired, add a layer of insulation between the plywood panels and the framework for added warmth and comfort. This is especially useful if you plan to camp in colder climates.
  • Finish the exterior of the camper with paint or a protective coating to protect the plywood from the elements. You can also add windows, doors, and other features at this stage.

Using plywood for your camper panels is a cost-effective and relatively easy way to build your own custom camper. With the right materials and careful construction, your plywood camper will provide many comfortable outdoor adventures.
