What Fireproof Materials Are Used for Container Houses

Container houses should be treated with Class A fireproof materials for fire prevention, such as rock wool boards, fireproof wool, and glass fiber fireproof boards.

Selection of Core Fireproof Materials

1. Rock Wool Boards/Fireproof Wool
   For the filling materials of the walls and roofs of container houses, Class A rock wool boards or fireproof wool should be preferred. These materials have a high fire resistance limit and do not burn at temperatures above 800℃, effectively blocking the spread of fire. For example, container houses used for residential or office purposes must use Class A rock wool fireproof boards to meet fire inspection requirements.

2. Glass Fiber Fireproof Boards
   Some container houses use glass fiber fireproof boards as floor or wall materials. These boards can withstand temperatures ranging from 1000 - 2000℃, have a combustion rating of Class A1 (non-combustible), and possess characteristics such as water resistance, light weight, and impact resistance, making them suitable for scenarios with high fire prevention requirements.

Key Points of Fireproof Design

1. Material Flame Retardancy
   Avoid using flammable materials such as polystyrene and polyurethane foam as core materials. These materials have a low ignition point, burn rapidly, and produce toxic smoke, greatly increasing the difficulty of personnel evacuation and fire extinguishment.

2. Structural Fire Protection
   Steel-structured container houses need to have fire protection treatment for their supporting members. For example, applying fireproof coatings or wrapping fireproof boards on the surface of steel can delay the deformation and collapse of the steel structure in a fire (usually requiring a fire resistance limit of more than 30 minutes).

3. Electrical Wiring Protection
   Electrical wires and cables should be equipped with protective sleeves. Socket and switch boxes should be made of metal galvanized boxes and installed in an exposed manner to avoid short circuits in the wiring that could cause fires. At the same time, simple fire extinguishing equipment should be provided inside container houses, and fire alarms can be installed if conditions permit.

Construction and Usage Specifications

1. Isolation of Open Flame Operations
   During the construction or maintenance of container houses, open flame operations such as electric welding and gas welding should be kept away from the core materials to avoid high-temperature sparks igniting flammable materials.

2. Control of Heat Source Distance
   During use, heat sources and fire sources (such as kitchens and heating equipment) should be kept at a safe distance from the walls of the container. If a kitchen needs to be set up inside the house, the walls should be equipped with fireproof rock wool insulation layers.

3. Safety Spacing Requirements
   Container houses should be spaced at least 6 meters apart to prevent the spread of fire through flying sparks or radiant heat. When multiple container houses are arranged in a concentrated manner, fire compartments should be divided and fire exits should be set up.
