How do I …Join the Composite Panels together?

Once you decide you want to build your project using one-piece Composite Panels, one of the first decisions to make is how you are going to join the panels together.

There are 2 main ways of doing this:

1.The DIY Panel Joiner system uses a range of aluminium extrusions to join the panels together and also attach the panel system to the trailer chassis.

Click here to read the details of the DIY Panel Joiner system which has the following advantages:

  • Creates a robust framework around all the panels
  • Ideal for off-road vehicles
  • Extra strength in the joins as panels attached over a large area
  • Provides strong fixing points internally and externally for other attachments eg awnings, internal components etc
  • Floor panel ‘traps’ the floor joiner onto the out-rigger system
  • Powder coated white finish

DIY Roof Corner Caps are also available to provide a water-tight seal at the top of the vertical joiners.

DIY Design note: Please note the Panel Joiner wall 29-29 can be used either way round – DIY recommends you design your project with the roof panel ‘over’ the wall panel – ie as shown below – and then follow this principle for the front wall and rear wall panels. The orientation of the panel joiner will also affect the precise dimensions required for each panel and how it goes together.

Note the roof panel is ‘over’ the wall panel

2. The Panel Rebate Method: The alternate method of joining panels is to rebate out one of the panel edges and fit the other panel into the rebate. Then you use aluminium angle to attach to the external and internal skins to make the join more robustThe alternate method of joining panels is to rebate out one of the panel edges and fit the other panel into the rebate. Then you use aluminium angle to attach to the external and internal skins to make the join more robust

This method may be simpler to install though customers should note that the main adhesion is between the skins and the aluminium trim – there is very little strength to be gained from adhesive applied to the edge of the core. DIY recommends attaching aluminium angle on both the external and internal edges of the panel join to enhance the strength of the join.
