Exterior wall installed on perimeter of OSB floor, yet rest of room is a cement slab?
We recently purchased a house and upon ripping the carpet out in one of the bedrooms noticed that the exterior wall has been built on top of an osb type floor, however directly adjacent is the cement slab. I’ve attached a picture.
I’m hoping that someone here may provide some insight into why the slab/osb combo has been used. The cement slab has heating put in the cement.
The house was built in 1998. It’s considered a ‘walkout’.
We are Alberta Canada. Thanks.
