The baseboards of our house have a 1/4 inch slot running through the horizontal length of them.
Only exterior wall baseboards have this and only on the North and South exterior walls.
We live in a single story house built in 1949, wood clapboard sided on a slab, no basement or crawl space.
Does anyone know what this design feature does? It's cold in Chicago and all it seems to do is let cold creep in this time of year and bugs in the summer. Thanks!!!:confused:
