There Are so Many Reasons for Wood Door Cracking. How to Choose and Prevent It?

Wooden doors are a popular choice for many homeowners due to their elegant and timeless aesthetic. However, it is important to note that many wooden doors may start to deform and crack after a certain period of use. Understanding the reasons for these issues and taking preventive measures can help ensure the longevity and durability of your wooden doors.

One common reason for cracking is insufficient or poor-quality glue used in the joints of the wooden door. Additionally, if the flatness of the door is less than 80%, it can contribute to cracking. Another factor is the relative humidity of the connected parts, where a difference of more than 2% or if the solid wood has a humidity level above 12%, can lead to cracks at the joints or the door core plate. To avoid these issues, it is essential to ensure that the doors are properly bonded and that the moisture content is within the recommended levels.

In some cases, cracks and deformations can also be attributed to the wood board itself. If the wood has not undergone proper drying treatment before being processed, the moisture content in the core of the board can be too high, while the surface remains dry. As a result, when exposed to fluctuations in temperature and humidity, the moisture will evaporate unevenly, leading to cracks. To prevent this, it is crucial to ensure that the wood boards used in the construction of the door have gone through the necessary drying processes.

The moisture content of the wood is another significant factor contributing to the deformation of wooden doors. As the moisture content decreases over time, the internal stress within the wood gradually manifests, resulting in deformation and cracking. Therefore, it is important to consider the moisture content of the wood when purchasing wooden doors. Additionally, factors such as the design structure, adherence to production processes, and environmental conditions can also influence the deformation and cracking of wooden doors.

To prevent these problems, there are some precautions that homeowners should take when selecting wooden doors. Firstly, it is crucial to choose products from reputable manufacturers who have conducted thorough research on various climatic conditions, including high temperature and high humidity environments. They will have the technical expertise to produce doors that can withstand different conditions.

Pay attention to the thickness of the wooden door as well. Thinner doors are lighter, and the recommended thickness range is typically between 38mm to 45mm. Doors within this range are less prone to deformations. Furthermore, consider the material of the wooden door by listening to the sound it produces when knocked. A good quality wood will have a mellow sound and distinct texture.

The paint process on the wooden door is also important. Look for doors with a high-quality paint finish that has a smooth and uniform texture. The strength and luster of the paint should be comparable to that of automotive metal paint. Lastly, inquire whether the door is a solid wood or composite as different materials have varying expansion and contraction coefficients. It is important to consider these factors especially during the hot summer months to prevent cracking.

In conclusion, while wooden doors can enhance the beauty of any home, it is essential to understand the reasons behind their potential cracking and deformation. Knowing the importance of glue quality, flatness, moisture content, design structure, and material selection is crucial before purchasing and installing wooden doors. By following these precautions and selecting high-quality products, homeowners can enjoy beautiful and long-lasting wooden doors without the worry of cracks and deformations.
