Isolating noise, cabin

I have driven this car about 10 kilometer all together. I did enjoy the sound of B18 with 2xSU, but less noise would be better. Sound isolation is and will be modest. It is very difficult to add proper isolation between cabin and engine.

Anyway, because the floor was repainted and at hand, I thought adding some extra insulation would not hurt. Maybe it would even protect the new paint.  And because it is out of sight, I could use a bit more modern material. STP Black Silver 1,8 mm was chosen. It has aluminium finish so it won’t stuck to anything.


Removing sticky old ones. There are potato chips also. There was none on the floor.

Found this. I understand there is Oxford Steel, but what is Conley ?

Because no air space is allowed, I prefilled slots with some extra stuff and managed to spend hours.

Don’t know if this helps at all. There is going to be one fabric isolation also under the floor mat.


I could add more. There were many plates in the box you know.

Such a handy roller pin is a… a handy tool. Aluminium may cause some bleeding otherwise.

    Where exactly was that Pressed Steel Co. patent plate located? I’ve never seen it on my father’s Jensen P1800 and I’m curious where to look! Was it actually hidden under the old tar boards? Later 1800S cars had such a plate on the right front fenderwell in the engine bay. It seem odd to install an elaborate badge where no one can see it! The name on the badge is Cowley Oxford, the suburb where Pressed Steel was founded.
