SOUND DEADENING + FLOOR
- Rattletrap Sound Deadener (recommended: 50 Sq Ft) (Buy on Amazon)
- I used 25′ Sq Ft, and kinda was wishing I had gotten more. It was enough to get a medium-small sized square on every large blank wall, but I did not put sound deadener on the floor, I did not cover the entire wheel wells, and I put minimal on the ceiling.
- Foamboard Adhesive (Buy on Amazon)
- (I would err on the side of buying too much of this! Like 2 per large piece of wood/foam. I ran out and had to use random adhesives I found lying around)
- 1/2″ XPS Rigid Foam Board
- WHY XPS? Despite having a lower R factor, it’s more rigid and therefore great to have as flooring/something to build on top of.
- WHY 1/2′? I wanted to keep the floor as low profile as possible so my head doesn’t hit the ceiling (I am 6’1″).
- HOW WARM? The floor is only “warm” in winter conditions when the heater is running and blowing heat on it. It cools off pretty quickly. We wear down booties ->(Buy on Amazon) and are very comfy in cold conditions.
- 1/2″ Plywood
- Spray Foam (Buy on Amazon)
- Laminate Flooring
- Glue for Laminate Flooring
- Silicone (Buy on Amazon)
- Aluminum edging
SOUND DEADENER INSTALL:
Installation of the Rattletrap Sound Deadener was really straightforward, I just rolled it on with the provided roller! Here is a helpful video I found that shows you how to install the deadener. Skip ahead to 1:21 if you want to get to the meat of the video.
I cut pieces of the XPS foam board to fit the profile of the floor.
I then took the foam board out and used it as a template to cut my plywood. I then glued down the foam board and plywood down using foamboard adhesive, and let it dry with weight on top of everything. I did not screw my floor down. Make sure you get the surface you will be applying the adhesive to nice and clean.
I did add more weight than what is in this photo, but still, I wish I had used more as I got some warping on the rear piece of plywood. Not too concerned because it is under the bed and has a lot of the build on top of it.
Once the plywood was in, I used spray foam to fill the gaps between the plywood and the walls and trimmed it back flat once dry.
I used a roll of laminate flooring from Home Depot, along with glue specifically for that type of flooring that I also got there. I had to cut it into two sections with a seam that would be located under the bed. I glued down the two pieces first, then used a box cutter to cut the edges to the curves of the van. Once dry I used silicone to seal the edges where the flooring met the walls. Where the two pieces of laminate met, I overlapped them slightly and used a straight edge to cut through them both, which resulted in a perfect seam between them.
Here is a in depth how-to that I followed when installing my floors.
I used aluminum stair edging and silicone to finish the edges showing in the door areas.
