Introduction To Interior Door Panels

Interior door panels are detachable wooden structures used to enclose entrances and exits in houses; remnants of wooden doors have been found in early archaeological sites. Traditionally, they are divided into two categories: simple wooden doors and movable doors for shops facing the street, serving functions of partitioning, protection, and decoration. Modern installation standards also specify requirements for the gap between the door leaf and the frame (e.g., approximately 3 mm at the top and sides, and 8-10 mm at the bottom) and installation precision.

Interior door panels are bonded to the substrate using a vacuum-adhesive film, with a double-sided process contributing to stability. Melamine boards use particleboard as the substrate and offer some moisture resistance. Painted boards use MDF with high-temperature spray painting, providing waterproof performance. Fireproof boards are made of multiple layers of kraft paper, resistant to high temperatures and abrasion. UV boards undergo environmentally friendly processes to achieve a glossy surface. Sintered stone door panels are characterized by high hardness and relatively easy installation. Composite multi-layer door panel processing optimizes the hot-pressing and static-setting process to address the issue of easy separation of the panels. In modern prefabricated houses, door panels are connected to supporting beams via a snap-fit ​​structure, becoming a fundamental building component.
