The inner core is made of high-quality particleboard, and the sound insulation effect can reach 32 decibels. Solid wood doors and solid wood composite doors, the higher the density, the heavier the weight, and the thicker the door panel, the better the sound insulation effect.

If both sides of the door panel are engraved with patterns, compared with the smooth door panel, it can play a certain role in absorbing sound and preventing repeated refraction of sound waves. Fire doors with sealing strips around the door also have good sound insulation effect. In addition, the installation between the door cover and the door is also the key to determine the sound insulation effect. Experts suggest that door covers and doors should be installed by experienced professionals.
