CA 2535278

The present invention is directed to a banded doorsill base for disposition between a pair of door jambs of a door frame. The doorsill base includes an elongate central portion formed from a polymeric material having a first coefficient of linear expansion, and first and second wooden strips bonded to and extending along opposite sides of the central portion for constraining the central portion and preventing linear expansion thereof. The first and second strips are formed from a material having a second coefficient of linear expansion less than the first coefficient. The first and second strips substantially prevent linear expansion of the central portion. The present invention also relates to a method of forming the banded doorsill base, and to a doorsill assembly having a banded doorsill base.
