The installation process for sliding interior doors presents an effective way to create more space within a room. This installation is conducted following the leveling of wall surfaces and the placement of finishing floors. If floor coverings are absent, it is imperative to calculate their thickness and incorporate this measurement into your assessments. Furthermore, before embarking on the installation of sliding doors, it is essential to verify the vertical alignment of the doorway and ascertain the desired direction for the door leaf to retract, thus freeing up the necessary space on the corresponding side.
