6 Steps for an Easy Sub-Wall and Sub-Ceiling Install
- 5/16 plywood (walls/ceiling)
- 3/4 plywood ( ripped into 2” pieces)
- sheet metal screws
- drywall screws
- liquid nails
- caulk gun
- power drill
- tape measure
- circular saw
- table saw
- miter box
- Scribe tool
The purpose of the sub-wall and sub-ceiling is to have something to anchor your walls/ceiling to. We chose to use recycled pallet wood. There are many different options out there you can use for your walls: tongue and groove, bamboo plywood, cedar, to name a few. We decided on recycled weathered pallet wood for a few different reasons. 1: It was free material. We found a shipping company that discarded the pallets when they were done with them. 2. We love the rustic look of the weathered boards.
Step 1: Scrape off all excess spray foam that covers your high ribs. You will need to secure the furring strips to these points and the excess foam will make it impossible to get a level and secure hold.

Step 2: Rip Furring Strips
“Rip” 3/4 inch plywood into two inch strips. A rip cut is to cut the wood in the direction of the grain. These two inch pieces will be secured into place with sheet metal screws to the high ribs of the interior of the van. These pieces are used as anchors for the plywood walls. Secure furring strips to the high ribs of the ceiling as well.

Step 3: Template your Plywood
Take cardboard and template around the grooves and curvatures of the ceiling and the floor. After you’ve made your template, trace onto the plywood and cut out using a jigsaw.
Step 4: Secure Walls into Place
Secure the plywood to the furring strips with drywall screws.
Pro Tip: To minimize vibrations/squeaking between the plywood and furring strips, apply glue.
Step 5: SubCeiling
Template your plywood for the ceiling being sure to work around the curvatures of the van. Mark where your lights will be and either cut out the hole now or later. We chose to cut them out after the plywood was up with a hole saw.
Step 6: Spray Foam Wheel Wells and Insulate Windows and Doors
After your sub-wall is installed, spray foam the wheel wells. This will help with insulation and sound deadening while driving.
