Joint tape reinforces drywall seams, butt joints, and patches — it's what prevents joint compound from cracking along the seam as the building moves and settles over time. Choosing the right tape type matters: paper tape for flat tapered seams where compound embeds the tape for a flush finish, fiberglass mesh for patches and areas requiring self-adhesive application. 

Pro Tool Haus carries both paper joint tape and fiberglass mesh tape in standard roll sizes for professional drywall work. Paper tape produces a stronger, flatter finish on tapered seams. Fiberglass mesh is faster for butt joints and repair patches where embedding tape into compound is less practical.
