Thickness of an internal dividing wall?

[EricP]

Two 1980 semis. Concrete block construction, london brick outer walls.

How thick is the party wall likely to be please?

Any rough ideas appreciated. (Plaster thickness disregarded)

The houses are as separate fire compartments, so the wall ought to be at least 9" thick.

Most likely 2 x 100mm plus a 50mm or 75mm cavity. Or solid 215 blockwork. Or 9" brick.

Or measure from halfway between yours and your neighbour's window. Measure from the internal reveal to the wall. Subtract the second from the first & multiply by 2 (assuming that the plaster on the reveal is the same thickness as that on the party wall).

Drill through next time they're out, and measure it... :o)

We did think of doing that in the loft. :))

I can't help but ask how this information will help you - what are you planning to do?

Might be a different thickness in the loft.

Or you might find their water tank.
