75mm Rock Wool/EPS Sandwich Panel: Thermal Insulation & Fireproof for Container House

The living and using experience of a container house corely depends on the choice of wall materials. All Anshiju container house products are standard equipped with 75mm rock wool/EPS sandwich panels, creating an exclusive "protective armor" for container houses from three dimensions of thermal insulation, fire prevention and durability, and completely breaking people’s stereotype of container houses as "hot in summer, cold in winter and poor fire resistance".

Rock wool sandwich panel is the core preferred material for container house walls, with particularly outstanding fire performance. Rock wool is a Class A non-combustible material with a melting point of more than 1000℃. It can effectively block the spread of flame in case of fire, with a fire resistance time of up to 4 hours, which fully meets the mandatory fire protection requirements for densely populated places such as camps and office areas. The 75mm thick rock wool sandwich panel adopted by Anshiju is made by precise technology, with a core material density of 100-160 kg/m³, which not only has strong compression resistance, but also can effectively absorb noise, keeping the interior of the container house away from external noise and creating a quiet office and living environment.

In terms of thermal insulation, the 75mm rock wool/EPS sandwich panel also performs brilliantly. The fiber structure of rock wool forms a large number of micro air holes, which can effectively block heat conduction, and its thermal conductivity is as low as 0.035-0.045 W/(m·K), far superior to ordinary concrete and wood. EPS sandwich panel further improves the thermal insulation effect by virtue of its closed-cell structure, making the container house "warm in winter and cool in summer". Even in cold northern areas or high-temperature southern areas, a comfortable internal temperature can be maintained without additional installation of a large number of heating and refrigeration equipment, greatly reducing the energy consumption of later use.

In addition to thermal insulation and fire prevention, Anshiju’s sandwich panels also solve the pain points of traditional rock wool panels such as easy water absorption and easy edge damage. The sandwich panels made by standardized technology use high-quality galvanized color steel plates for the panels, which are closely attached to the core material with excellent sealing performance, effectively preventing rainwater penetration and extending the service life of the walls. At the same time, the 75mm thickness balances structural lightness and performance stability, which does not increase the overall load of the container house, but also ensures the firmness of the wall, adapting to the use needs of transportation, hoisting and multiple disassembly and assembly.

A good container house starts with a good wall. The standard configuration of 75mm rock wool/EPS sandwich panels makes Anshiju container houses superior in quality, creating a safe, comfortable and durable internal space for users in different scenarios.
