Wooden door is not only a combination of door skin and door core but also it’s a feeling and understanding and expression for your needs. Shandong Xing Yuan is determined to create a better solution of wooden door infilling materials, the door core.
Two of the common door core types found in modern door production are solid chipboard and tubular chipboard. Both have their own set of structure, functionality, and best uses. So which is best for you? Let’s explore more for you.
1. Density
Solid chipboards often have density of 600kg/m³,which makes it very heavy for doors.If you reduce two much density to it, to 500kg/m³ for example,solid chipboard may break easily,especially for thicker ones,like 44mm ones. Shandong Xing Yuan now can produce NFR chipboard and FR chipboard, which are tested by SGS and widely used in the enviroment which needs fire-proof materials. In different uses, we can offer FR 30mins,FR 60mins,FR 90mins panels. Solid chipboard is heavier and denser. As a well-filled material, they have a firm, solid structure. Although weight is excellent for insulation and stability, it demands heavy-duty hardware and careful treatment when installing.
Tubular chipboard can reduce density up to 50-60% or so,compared with solid chipboard. This is implemmented by its structure: tubes inside.This light weight makes them perfect for interior door use as it is easier to handle. Less weight also means less stress on hardware and hinges, as it does not compromise on performance and will last over the years.
2. Structure
Tubular chipboard features an internal grid pattern in the door made of engineered tubes forming without compromising structural strength. This makes them an excellent option in homes and companies where performance and weight saving are critical factors to consider.
Solid chipboards have no tubes inside. This form of building offers additional impact strength, sound-proofing, and durablity.
3. Sound & Impact Resistance
Although there are tubes in the inner layer,tubular chipboard is still not weak. Both impact and sound are well-absorbed by the tubes, which is a critical requirement for busy family homes or offices with heavy traffic.
However, if you need strong interior doors with much more strength, solid chipboard is still your best choice,especially for fire-rated enviroments. The high-density composition makes solid chipboard an ideal infilling materials for doors that face regular force such as in schools, hotels, or high-security zones.
4. Dimensional Stability
Both tubular chipboard and solid chipboard have great dimensional stability. They are less possible to bend than solid timber door core infillings.
Shandong Xing Yuan offers standard E1 glue,which makes the door core can be used in indoor situations. You never have to sacrifice visual perfection or durability over the years with them.
6. Bending Possiblity
Chipboard offers a unique balance,while solid timber often faces the bending problems. It resists warping and is able to adapt to subtle shifts in the environment. They also have their lighter weight contribute to the resistance against sagging with time.
7. Cost & Budget
One of the reason why we need to use tubular chipboard is the low cost. Tubes inside not only reduce the weight but also brings more benifs, such as simplify installation, and high performance at a cost-competitive price.
Solid chipboards require a higher initial investment, but are cost effective given their long lasting durability.
8. Conclusion
Tubular chipboard: suitable for wooden doors in bedrooms, study rooms, and other inner rooms where efficiency and lightness are important. Also ideal for minimalistic interiors where smooth functionality is sought.
Solid chipboard: most suitable for front doors, fire-rated areas, and sound-controlled rooms. Their sturdy nature provides reassurance and a touch of luxury to expansive architectural designs.
At Shandong Xing Yuan, we put the quanlity first,then offer you with competitive prices. Welcome your inquiry on us.
