Do you know how many kinds of internal filling materials there are for indoor wooden doors?

Density board
Material characteristics: Made of wood fiber or other plant fiber, with fine structure and smooth surface.
Advantages: Easy to process and shape, can achieve complex carving design, good sound insulation effect, relatively moderate price.
Disadvantages: Poor moisture resistance, easy to expand and deform in long-term contact with humid environment, environmental protection depends on the amount of formaldehyde released.

Solid wood integrated material
Material characteristics: Small pieces of solid wood are spliced ​​together to retain the natural texture of solid wood.
Advantages: It has good solid wood characteristics, high strength, strong stability, relatively high environmental protection, good texture and grade.
Disadvantages: High cost, heavy weight, high requirements for production process, and there may be a certain risk of shrinkage and deformation.

Honeycomb paper
Material characteristics: Honeycomb structure made of paper material.
Advantages: light weight, can reduce the overall weight of the door, reduce the difficulty of transportation and installation, low cost, and has certain sound insulation and buffering effects.
Disadvantages: relatively low strength, poor anti-collision performance, poor waterproofness, and aging problems may occur after long-term use.

Particleboard
Material characteristics: made of wood chips after bonding and pressing, with loose structure.
Advantages: low price, good processing performance, and can meet basic use needs.
Disadvantages: poor strength and moisture resistance, environmental protection also needs to be paid attention to, and long-term use is prone to cracking and other problems.

Aluminum honeycomb
Material characteristics: honeycomb structure made of aluminum alloy.
Advantages: light weight, high strength, corrosion resistance, good fire resistance, strong environmental protection, and long service life.
Disadvantages: high cost, mainly used for high-end wooden doors or occasions with high performance requirements.
Different filling materials are suitable for different scenarios and needs. When consumers choose indoor wooden doors, they can make comprehensive considerations based on their own budget, use environment and performance requirements.
