We built a simple wooden trim for our van conversion window installation.
When you look at professional Conversion Van build-outs you will often notice how neat and finished the window trims look. The metal van frame and window just doesn’t look quite as polished as a well-done trim. See how we finished our wall panels and window installation with this relatively easy to build…….
Van Conversion Window Trim
This project was daunting at first, but after thinking about it for a while, we settled on a simple design and installation method.
Van Window Trim – Design Challenges
Cutting Out The Hole
Lining up the cutout and cutting the hole the correct size. In hindsight, I wish we kept the template for the window installation, as this would have been perfect for marking the hole for the van window trim.
Securing The Van Window Trim.
For this, we decided to use two cover pieces, one on the top and one on the bottom. In addition, each end will be secured behind trim panels. Furthermore, the trim itself is very stiff due to the recess framing so it will be held securely in place.
2-Piece VS 1-Piece Design.
Because the panel will sit behind the factory B-Panel trim, it will need to be made in two pieces that screw together. The recessed frame will go in then the window frame will go on top.
Two-tone color scheme.
Buy building this trim panel in two pieces, it is easy to continue the two-tone Black and Grey color scheme.
Van Conversion Window Trim – How We Built It
The Tools And Materials
- Jigsaw
- Extra Strength Wood Glue
- Surform Pocket Plane / Rasp
- Circular Saw
- Drill and Drill Bits
- ¼” Baltic Birch Plywood
- Scotch Brite Scuff Pads
- Carpenter Pencils
- Paint Brushes
- Self Adhering, Foil Backed, Thermal Acoustic Insulation (eBay)
- 3ft Metal Ruler
- 10-24 Threaded Inserts
- 160grit Sandpaper
- Varathane Stain Carbon Grey
- Varathane Polyurethane
The Steps
Step-1 Mark and Cut The Window Trim Panel
We had the trim panel piece ripped at the correct width by our local wood supplier. We then used our Circular Saw to cut it to the correct length. Then, we marked out a cut mark then used our Jigsaw to cut it out. 
Pro Tip* when using a Circular Saw to Baltic Birch Plywood. Put the face side down to prevent splintering of the wood.
Step- 2 Cut Out The Recess Frame Pieces
The window frame pieces are cut with a taper to fit the shape of the van walls. We also notched out the corners to fit. 
Step- 3 Glue Together The Recessed Frame Pieces
We used some trim moulding to add strength as well as give a decorative finish to the corners. Then we glued on pieces to screw into, these side pieces will also add strength and rigidity.
Step- 4 Install Threaded Inserts
Next, to screw the frame and panel together, we installed Knife Threaded Inserts on around the recessed frame. We backed up the wood with a clamp to prevent splitting when screwing in the inserts. 
Step- 5 Test Fit
We had to drill out the holes a little more to get it to fit, no problem though as the finishing washers cover-up the holes no problem. 
Step- 6 Stain And Seal
First A light sand on the edges to remove any splinters, then two coats of stain and sealer. 
Pro Tip* Scuffing with Scotch Brite Scuff Pads between coats is an easy way to get a nice smooth finish.
Step- 7 Cover With Thermal Acoustic Heat Barrier Insulation
This stuff from eBay is magic, we have noticed a huge improvement in space comfort by adding this to the back side of all our panels. Retain heat in the winter and reduce heat in the summer! Win-win! 
Step- 8 Van Conversion Window Trim – Installation
The best part was seeing all our hard work come together installing our new van conversion window trim.
Another Project Done ✅
With Christmas and school holidays, this project took a while to complete, one month from start to finish. Even so, there is something relaxing and rewarding about taking your time and doing something to the best of your abilities. Now I’m sure there are professional woodworkers who can do a much better job, but I am extremely happy with the results. Another project done.

Ben, how did you attach the trim ring to the window or wall? I re read the securing section.
Does the trim ring clamp around the window frame?
Thanks for the inspiration. We’ve been staring at the window and your write up has been helpful in figuring out what we’ll do.
Hey Casey, thanks for reaching out.
The trim panel slots in behind the factory trim before screwing into the recessed frame. It will be secured at the pillar behind another trim piece, but as it is, it holds in place securely just like that.
Hope that helps.
