Sprinter PA 14 Motor Home Build (Sound Proofing, Insulating, Laying Floor)

Sprinter Motor Home Build:

The next job on the list was to soundproof all the panels in the van from front to back.

I used Silent Coat for this as it’s about the best sound deadening on the market.


It is not the cheapest but this is important and I wanted to do it right the first time.

I Probably used two boxes to do the van give or take a sheet.

Once you have cut the sheet to fit. All you have to do is peel off the backing paper and stick it in place.

You then warm it up with a heat gun or hairdryer.

Using a hard nylon roller to “press it down” so it is stuck firmly.

This means the sheets then won’t peel off when the van gets hot in the summer.

When the sun is beating down on the exterior panels they get very warm.

I also forgot to mention previously:

I had drilled a load of 32mm holes and painted with red oxide primer. To prevent rust in the walls and hard to reach places.

This was so I could fill with “Recycled Plastic Insulation”. I will use this insulation everywhere I can fit a sheet of “Kingspan” solid insulation board.

It has great insulating properties. Its also waterproof and mice, rat, and bug repellant which is handy and makes it ideal for this project.

As you will see I have started to stuff it in around the windows of the van. In all the cavities with a “handy pokey stick”.

(DO NOT USE YOUR FINGER AS THE VAN WALLS ARE SHARP AS F£$K)

Next on the list was to lay 25mm by 38mm batten (Kingspan is 25mm thick) across the floor.

Spaced out at 600mm intervals (half a sheet of Kingspan).

I fixed these down by screwing them to the floor with normal wood screws with a blob of CT1 silicone.

So, after this was complete I had to cut and fit the 25mm insulation board in between the battens which I held down with a few more blobs of CT1 silicon.

Once this was set I filled any little remaining gaps with expanding foam and once dry cut off with a hack saw blade.

Once the dry expanding foam has been trimmed and cleaned.

Next time to lay a layer of foil bubble wrap as a vapor barrier and extra insulation.

Glued down with high temp spray adhesive.

I then continued all the way up to behind the front seats with the same method. Next, I had the hard task of marking out the plywood floor to cut out the shape of the frame.

Without being able to see what I was doing, I then set about cutting the plywood flooring and fastened it down by screwing through into the battens I had fixed to the floor

Next post we will move on to walls and start build the first kayak box
