    The door leaf molding is mainly made of new galvanized steel plates, professional soundproof materials, damping soundproof panels, soundproof cotton, etc.

    At the same time, the most important thing about soundproof doors is sealing treatment.

    The use of magnetic control seals can ensure a good sealing and sound insulation effect.

    STC 45 door specifications

    Dimensions of door frame : 910x2100mm, 1500x2100mm

    Thickness of door leaf: 45-90mm

    Acoustic performance: Rw 20 - Rw 50 * (STC 38 db - STC 55db)

    Hardware accessories: self-lowering door bottom seals, side strips, locks, door closers (optional).

    Finishes: natural veneer, technical veneer, HPL, environmentally friendly paint, transfer printing, etc.

    STC 45 door features

    STC 45 door adopts multi-layer composite, special sound insulation structure, and can withstand high temperature and aerodynamic load.

    Soundproof doors are divided into single-door and double-doors.

    The sound proofing performance of single-door is obviously better than that of double-doors.

    It can also be equipped with an observation window, reliable sealing and flexible opening.

    The production of professional soundproof doors basically does not adopt a push-pull structure, and the push-pull type is not conducive to sealing treatment, which will greatly affect the overall performance of sound insulation.

    STC 45 door applications

    The professional high stc door is mainly used in various testing rooms, movie studios, studios, recording studios and other places.

    About installation

    The pre-embedded parts of the high stc door should be installed during civil construction, or they can be designed and manufactured separately according to customer requirements.

    The way that the sound wave transmits through the door is mainly from door leaf and gaps.

    Therefore, to achieve a better sound insulation performance, it is necessary to start from the below two parts.

    Improve the sound insulation of the door leaf

    In order to ensure the door closing is light and flexible, it is impossible to excessively increase the door leaf and reorganize the method to achieve a higher sound insulation capacity.

    You can use:

    1 - Combine different acoustic resistance materials to form a multi-layer composite door leaf.

    2 - Prevent the anastomotic effect of the panel from appearing in the effective frequency range to reduce the sound insulation.

    Improve the sealing of the door gap

    1 - The effect of the door gap on the sound insulation is the change in the sound insulation when different door gap sealing methods are used on the same door.

    2 - The method of sealing the door gap


    "9" shaped rubber sealing strip


    Adopt dual-channel sealing strip.
