Wooden Doors

Wooden doors can cost thousands.

Why are wooden doors so expensive?

How can you identify a good door?

When choosing a wooden door, quality is key.

Wooden doors are categorized based on their core materials.

The difference in core materials largely determines the quality of the door.

This is also a crucial factor in selecting a high-quality wooden door.

The price composition of a wooden door is approximately:

Door core: Surface: Door frame = 5:3:2

If the door core is made of solid, high-quality wood, the cost will be high.

If the door core is made of glued wood chips to form a hollow core door panel,

the cost will be very low.


Bridge Hole Particle Board

Bridge hole particle board is a common material in the home furnishing industry and is also widely used in wooden doors. Due to its low cost, it is favored by some small wooden door manufacturers. However, the essence of bridge hole particle board is the use of a large amount of glue to bond and compress wood scraps, resulting in high formaldehyde content, poor load-bearing capacity, and poor anti-deformation performance. Additionally, because it is a hollow structure, its sound insulation effect is also poor.


Particle Board

Particle board is a type of board made by crushing natural wood into particles and then pressing it with glue. It is low-cost and has poor moisture resistance. Typically, the door core uses a three-layer composite particle board, which has better overall performance than honeycomb paper filling but is slightly more expensive.


Density Board

Density board, also known as MDF (Medium Density Fiberboard), is a very common wood door core material in the market. It is made from wood fibers or other plant fibers, combined with adhesive substances to form an artificial board. To save costs, manufacturers often use the wet process to produce fiberboard. Due to the net pattern on its back, the surface area of the two sides of the fiberboard is unequal, making it prone to warping and deformation when exposed to moisture, thus making it impractical.


Honeycomb Paper

Honeycomb paper is made based on the honeycomb structure principle found in nature. It involves gluing corrugated paper into numerous hollow three-dimensional hexagons to form an integral force-bearing paper core. It is lightweight, uses less material, and is low-cost. However, it has fatal drawbacks: it has very poor resistance to damage, is easily destroyed, and has very poor moisture resistance. Wooden doors with honeycomb paper as the core material generally have a short lifespan and are very impractical.


Oriented Strand Board (OSB)

Oriented Strand Board (OSB), also known as LVL (Laminated Veneer Lumber), is made by hot-pressing and gluing multiple layers of veneer. It has minimal deformation, high strength, and stable structure. Due to the oriented gluing and high-temperature high-pressure process, it addresses the deformation defects of wood from the internal stress aspect. Fuqing LVL enhances the product’s moisture resistance according to regional differences, preventing deformation and warping caused by humid environments. Additionally, Fuqing LVL delves into the environmental needs of interior doors and has independently developed resin adhesives that meet the new national standard ENF level, ensuring a healthy living environment.


As an essential part of home decoration, the choice of wooden doors determines the health of the home environment. It is important to choose high-quality core materials and use high-quality wooden doors. Fuqing LVL has been deeply involved in wood manufacturing for 33 years and is the “drafting unit of the national standard for LVL (Laminated Veneer Lumber).” Fuqing LVL is synonymous with quality and environmental protection!


For wooden doors that resist deformation, use Fuqing door core materials!
