1. There are dead corners where dust accumulates, and cleaning and maintenance are relatively cumbersome
This is the most obvious weakness of grille products. Due to the surface being composed of raised wooden strips arranged one by one, dust is easily accumulated on the sides and gaps of the wooden strips. In dry areas or open spaces in the north, daily maintenance requires the use of a feather duster, electrostatic precipitator, or vacuum cleaner to clean grooves, which cannot be wiped to the bottom with a cloth like ordinary flat walls. For people who have a "cleanliness obsession" or are unwilling to spend too much energy on household chores, it will increase a certain maintenance burden.
2. Limited moisture and water resistance, not suitable for extremely humid environments
Although products on the market undergo sealing treatment, their essence is still wooden substrates (such as density boards, solid wood multi-layer boards, etc.). If exposed to extremely humid environments for a long time (such as inside bathrooms without dry wet separation, or basement on the first floor that is constantly damp), wood still faces the risk of water absorption, expansion, deformation, and even mold growth. In addition, if the sound-absorbing felt behind it gets damp, its sound-absorbing performance will also be greatly reduced. Therefore, it is more suitable for relatively dry indoor spaces such as living rooms, bedrooms, and study rooms.
3. Sound insulation ≠ Sound absorption, limited effectiveness in isolating external noiseMany consumers tend to confuse these two concepts.
The core strength of wooden grille sound-absorbing panels is "sound absorption", which means absorbing indoor echoes and reverberations, making the sound sound clearer and less noisy; But its "sound insulation" ability (blocking the sound from neighboring or outdoor areas) is relatively limited. If your house is facing the street with loud noise or you want to completely isolate the noisy neighbors, relying solely on this thin layer of grille panel is not enough. Usually, it is necessary to install professional soundproof felt, soundproof cotton or make a double-layer wall structure at the base of the wall.
