实木复合门的门芯多以松木、杉木或进口填充材料等粘合而成。外贴密度板和实木木皮，经高温热压后制成，并用实木线条封边。一般高级的实木复合门，其门芯多为优质白松，表面则为实木单板。由于白松密度小，重量轻，且较容易控制含水率，因而成品门的重量都较轻，也不易变形、开裂。另外，实木复合门还具有保温、耐冲击、阻燃等特点，而且隔音效果同实木门基本相同。
The core of solid wood composite door is mostly made of pine, fir or imported filling materials. The density board and solid wood veneer are pasted on the outside, which are made by hot pressing at high temperature and sealed with solid wood lines. General high-grade solid wood composite door, the door core is mostly high-quality white pine, the surface is solid wood veneer. Due to its small density, light weight and easy to control the moisture content, the finished doors are light in weight and not easy to deform and crack. In addition, the solid wood composite door also has the characteristics of heat preservation, impact resistance, flame retardant, and the sound insulation effect is basically the same as the solid wood door.
