Converting Laundry room into bedroom
« on: March 17, 2018, 06:53:53 AM »

I am looking to convert my laundry room (1st floor, next to driveway/ semi-busy 35mph street) into a bedroom.
It currently has drywall on 3 sides, and 1950s plaster on driveway side (and I believe ceiling).

I am considering the option of opening all walls and redoing some electrical, and re-closing them with modern methods. Sound absorption is important to me, and I would like to not be able to hear conversations/cars in the bedroom (driveway wall).

I hear it's good, but I was not able to find the STC of plaster&lathe. Does anyone know it?
My plaster is 1" thick with a gypsum board as base & mesh wire.

How do the current methods compare to plaster?
I am familiar with the MLV/clip & furring channels, having installed your products in another room.

Is it worth opening this wall to add a couple romex cables, or should I leave it untouched?
or just fur over it and try to fish the romex through the ceiling instead?

It is worth noting that this wall has a window, making decoupling through channels tricky.

We need to start this off the right way and that would be the weak spot of the window and its location.

If and when the window STC rating is improved then we can justify soundproofing the walls.
best to make the "bubble" (room) equal STC value.

It would be best to call me direct and discuss the particulars.
