Hi mbe,
How old is the house you live in?
I ask this question because they used to put what was called a plank board inside/between the plasterboards on stud partion walls. The plank was about an inch thick, sometimes it would be double boarded with either the plank or the outer boards. This was for sound-proofing, insolation etc. There was not a lot of timber/steel stud work in these types of wall, usually along top and bottom and up both sides. This was very popular in the late 70's to mid 90's. This could be what you have in your house.
