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

Many wooden doors may initially look appealing when they are first purchased, but over time, they can become prone to deformation and cracking. It is important to understand the reasons behind these issues before purchasing and installing wooden doors, as well as strategies to avoid them.

One common cause of cracking in wooden doors is insufficient or poor quality glue used in the joints. 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 being greater than 2% or if the solid wood itself has humidity levels exceeding 12%. These conditions can lead to cracking at the joint between the rung and vertical rung or the door core plate.

The wood board used in the door can also develop cracks if it has not undergone proper drying treatment before processing. When the moisture content in the core of the board is too high and the surface is dry, the moisture can escape due to changes in ambient temperature and humidity, resulting in cracking.

Moisture content is another major factor that can cause deformation in wooden doors. As the moisture content decreases over time, the internal stress of the wood will be revealed, leading to deformation and cracking. The design structure of the wooden door is also essential, as a poorly designed structure or failure to follow proper production processes can contribute to deformation. Additionally, the curing of adhesive, transportation, placement, and environmental conditions in the place of usage can impact the wooden door's propensity for deformation.

Material problems also play a significant role in the deformation and cracking of wooden doors. Both solid wood doors and solid wood composite doors have wood components that are susceptible to dry shrinkage and moisture expansion. Wood is a natural material, making it more prone to deformation than synthetic materials. Additionally, the large surface area and few fixed points in a wooden door make it more susceptible to deformation and cracking.

To avoid these problems, there are several precautions to consider when selecting wooden doors. It is vital to choose products from qualified manufacturers who have conducted in-depth research on various climate and environmental conditions. Paying attention to the thickness of the door is crucial, as thinner handles are lighter and less likely to deform. The recommended thickness for a wooden door is typically between 38mm-45mm. Evaluating the material used is also important—knocking on the door can help determine if the wood has a mellow sound with texture, indicating good quality. The paint process on the wooden door should be carefully examined for a uniform luster and color, comparable to automobile metal paint. Asking whether the door is solid wood or composite is essential, as understanding the principles of heat expansion and contraction can help prevent cracking.

In conclusion, understanding the reasons behind the cracking and deformation of wooden doors is essential for making an informed purchase decision. By considering factors such as glue quality, flatness, moisture content, design structure, material, and paint process, individuals can choose high-quality wooden doors that are less prone to these issues. Taking these precautions will ensure that the wooden doors maintain their aesthetic appeal and functionality for an extended period.

There are so many reasons for wood door cracking, such as changes in humidity and temperature. To prevent it, choose a high-quality wood and maintain appropriate humidity levels. Regularly inspect and maintain the door to prevent cracking.

In conclusion, wood door cracking can occur due to various reasons such as changes in humidity, poor installation, or low-quality wood. To choose and prevent it, consider investing in high-quality, well-sealed wood doors and maintaining proper humidity levels in your home. Regular maintenance and addressing any issues promptly can help prevent wood door cracking and prolong the life of your doors.
