Board-and-Bat Configuration
Board-and-Bat is installed by placing wider boards on the wall first, with a gap of a couple inches in between the boards. Narrower "bats" are then placed over the gaps, overlapping the wider boards by 1/2" to 1".
Board-and-Bat siding was most popular on American houses in the 1845 to 1865 timeframe and was viewed by its proponents as an expression of the house's frame within. Board-and-Bat siding is a perfect choice for the customer who wishes to draw upon historically accurate designs.
