First, look at the thickness of the door frame: after the general situation, the thicker the door frame, the better the actual effect of sound insulation and noise reduction, such as carbon crystal indoor wooden door specification thickness is 4.5cm, much higher than the small well-known brands on the sales market 4.0cm, but also in accordance with the specific requirements of the customer to improve the door page thickness, to ensure adequate sound insulation actual effect.

Second, look at the filling material: we all know that the greater the relative density of the filling material, the better the actual effect of noise isolation, therefore, in the case of selecting the glottis, we can distinguish the quality of the filling material according to the net weight of the door. For example, the carbon crystal indoor wood door filling is pure solid wood filling, the filling rate is 75%, and the door frame is heat-insulating. At the same time, the embedded 25% indoor space wood itself heats up and cools down the indoor space, which is used to prevent moisture from rising and increase the service life of the goods.

Third, the house: the door cover will also greatly harm the actual effect of indoor carbon crystal indoor wood door insulation, after all, the door is embedded in the door cover, it involves the door frame problem, the bigger the door gap, the worse the actual effect of sound insulation and noise reduction.
