What is jit
JIT tile backer boards have an extruded polystyrene foam core and a fiberglass reinforced cement coating. This makes the JIT panels strong, light and water proof. JIT panels are the perfect choice for a variety of applications. They are used as an interlayer to walls, floors, and underfloor heating systems. The cement coating is ready for all types of tile including ceramic, glass or stone tiles in mosaic or large format.
