It is easily damaged in winter. In the winter, the temperature will drop, and the inferior seals are likely to lose their original softness, become very stiff, lack elasticity, and are likely to be damaged when the wooden door is opened and closed.

Soundproof and dustproof effect is poor. The reason why the sealing strip is called a sealing strip lies in its sealing property. The inferior sealing strip is not very good in sealing due to its material and the like. Especially in the winter, due to the relationship between thermal expansion and contraction, the sealing strip is constantly shrinking, so that a large gap is formed in the closed portion of the wooden door, and the airtightness and dustproofness become poor.

Not conducive to the protection of wooden doors. In addition to sound and dust, the other function of the seal is to protect the wooden door. Inferior sealing strips have insufficient toughness. When opening and closing wooden doors, the buffering effect is not good. The use of protective wooden doors is not very strong, especially in winter, because the inferior sealing strips become very stiff, the protection effect is even worse. . The above list is about the harm of inferior wooden door seals. In fact, the shortcomings may be far more than these. Please pay attention to these when purchasing. It is necessary to choose a large manufacturer with guaranteed quality.
