Integrated wall panels sound insulation effect is excellent, tested up to 29 decibels, equivalent to the sound insulation effect of the solid wall, can effectively block the outside world noise, whether it is the sound of sirens, machine noise or car roar, it is difficult to penetrate this “sound barrier”, to create a quiet and comfortable living and working environment for users. In moisture-proof and waterproof performance, integrated wallboard performance excellence, its substrate using polymer resin by high temperature foam extrusion molding process, the formation of closed-cell structure, water vapor moisture is difficult to invade, effectively solving the problem of moldy walls, alkali and other issues, especially for the southern humid areas as well as bathrooms, kitchens and other spaces with more water vapor. Moreover, it is high strength, good toughness, impact resistance, friction resistance, surface treatment using advanced technology, not only fashionable and beautiful, but also extremely easy to clean, can be scrubbed directly with water, no blistering, no deformation, easy and convenient daily maintenance.
