What is the soundproof door against

There must be a principle for sound insulation of soundproof doors. What is the sound insulation of fireproof doors? Today, I will make up a short story to answer your questions one by one.

Sound insulation doors mainly rely on the door leaves to achieve the sound insulation effect. This type of door leaves mostly use new galvanized steel plates, and the interior uses good sound insulation materials, sound insulation cotton, or damping sound insulation boards. At the same time, they are sealed in the outer frame. The common one is the magnetic control seal, which has the sealing effect and the function of blocking noise is increased.

The sound insulation door of Xuanyuan Gate adopts multi-layer composite, special sound insulation structure, and can withstand high temperature and pneumatic load.

Sound insulation doors are divided into single door and double door. The sound insulation effect of single door is obviously better than that of double door.

With observation window, it can be sealed reliably and opened flexibly. The soundproof door is basically made without a push-pull structure. The push-pull type is not conducive to the sealing treatment and will greatly affect the overall effect of sound insulation.
