Standards and detailed explanations for steel fireproof and soundproof doors

Abstract: Fireproof and soundproof doors have both soundproofing and fireproofing properties. Fireproof and soundproof doors are made of high-precision cold-rolled steel plates as standard. The cavity of the door body is filled with soundproofing material. The volumetric weight of the soundproofing material is controlled within 50~100KG/m3. The door is sealed with rubber strips to ensure the convenience of use and achieve the best performance. Sound insulation effect, its sound insulation index is divided into four types: 30dB, 35dB, 40dB, 45dB (A). The sound insulation design varies according to different usage environments. The higher the decibel value, the higher the sound insulation performance. Let’s find out more about it with the editor below.

How to choose a suitable fireproof and soundproof door? Fireproof and soundproof doors are special doors and windows with fireproof door performance and sound insulation effect. They are used in many places. It is mainly used in cinema passage doors, equipment room doors, and KTV club house doors. It is usually used for the passage of people. When a fire occurs, the door leaf automatically closes, effectively preventing the spread of fire, and has a fire-proof sealing effect. The product implementation standard is based on \”GB12955- 2008 Standards for Fireproof Doors and Windows\” and \”Design Standards for Noise Control of Industrial Enterprises\”.

Fireproof and soundproof doors are made of high-precision cold-rolled steel plates using cold processes. The cavity of the door body is filled with fireproof and sound insulation materials, and the bulk density of the sound insulation materials is controlled within 50~100KG/m3. The door is sealed with rubber strips all around to achieve fire protection and sound insulation.

Fireproof and soundproof doors mainly start from the hardware structure and materials. In terms of structural materials, soundproof door manufacturers focus on door frames and The door side is made of high-tech aluminum-magnesium-titanium alloy material. The surface is anodized and has a certain hardness. Thus, improvements can be made in aspects such as wear resistance, pressure resistance, deformation resistance and fading resistance.

① The sound insulation materials in the sound insulation door leaf are filled with sound-absorbing cotton, honeycomb structure, PU, ​​and sound insulation materials according to the sound insulation level (sound insulation materials mainly include damping rubber panels and mineral wool sound insulation panels) ), using unique settingsTaking into account special seal fabrication.

② The soundproof door technology adopts single or double cuts, which has excellent fire protection, sound insulation and escape properties. It has stable performance and is a soundproof door made with precision. Fireproof soundproof doors are divided into wooden soundproof doors and steel soundproof doors. The products can be customized according to user requirements.

③ The door core structure inside the fireproof soundproof door. The soundproof door manufacturer uses aluminum honeycomb. Aluminum honeycomb is made of high-performance aluminum, so the materials used are relatively Rigorous, the honeycomb shape is also very durable.

④ The standard sound insulation index of fireproof soundproof doors is divided into four types: 30dB, 35dB, 40dB, and 45dB (A).

Measurement and installation of fireproof and soundproof doors: For better soundproofing and fireproofing effects, it is important to measure the dimensions before customizing. The width and height of the door opening are measured separately and the smallest value is taken. Inform the wall thickness and structure, and opening direction. According to fire protection requirements, passage fire doors cannot have bottom frames (except for computer rooms and equipment rooms). Fireproof and soundproof doors must be installed horizontally and vertically with tight seams. If not installed properly, even small seams will damage the soundproof door. sound insulation performance. After the installation is completed, the door frame needs to be filled with cement mortar to ensure firmness and fireproof and sound insulation effects. Coolstic Doors and Windows Company can provide door-to-door measurement and installation. For areas where the project is far away, it is recommended to find a local professional installation team or our company to provide technical support.
