What Is This White Piece of Wood Under the Door Sill Plate Called? What Material To Replace?

I'm having my front door replaced with a new pre-hung door. New door will include a new aluminum sill plate, but I would like to replace the piece of white wood that sits UNDER the sill plate, on top of the concrete landing pad. Is there a specific industry term for that piece of white wood? I've come across videos of it being referred to as "Door Sill / Threshold," using them interchangeably with the actual aluminum sill plate. Also, what type of material can be used to replace this piece? Pressure-treated lumber? Does any PVC/Composite material exist for this piece? https://preview.redd.it/1mznwcdjrf3f1.jpg?width=4032&format=pjpg&auto=webp&s=348dd9e92226c5ce82bbf27671c3eb827c38b6b5 submitted by /u/oldmanmachine [link] [comments]
