Warehouse office built with rockwool fireproof panels

A private warehouse in a residential area in New South Wales, Australia, the customer ordered rock wool sandwich panels from China for office construction. Yirong sandwich panel supplier customized 75mm thick rock wool fireproof panels for it, completing the construction of indoor warehouse offices and outdoor small offices.

As the core material of this project, Yirong 75mm thick rock wool fireproof panels meet Australia's strict building regulations and climate characteristics. Its core sandwich layer is filled with high-density rock wool, with a density of 140kg/m³ and a thermal conductivity as low as 0.038W/(m·K). It not only meets the A1 non-combustible certification of the Australian AS 1530.4 standard, but also continues to burn for 2 hours without collapse under the impact of 1000℃ flames. It also achieves dual upgrades of fire prevention and heat insulation with a golden thickness of 75mm.

Compared with conventional 50mm rock wool panel, its fire resistance limit is extended by 30%, and the indoor temperature in summer is 8-10℃ lower than that of traditional color steel plate, which greatly reduces air conditioning energy consumption. In winter, the temperature fluctuation of the cargo storage environment in the warehouse will be controlled within ±2℃, providing stable protection for precision instruments, electronic components and other materials that are sensitive to temperature and humidity.

Aiming at the application differences of indoor and outdoor scenes, Yirong has customized and optimized the board. The surface of the rock wool board used in the indoor warehouse office is covered with 0.5mm thick aluminum-zinc-plated steel plate, which not only has excellent corrosion resistance, but also is processed by micro-arc oxidation process, so that the metal panel presents a delicate matte texture, which perfectly blends with the neat industrial style in the warehouse. The board of the outdoor small office has an additional UV coating, which can effectively resist the strong ultraviolet radiation in Australia. The color difference of the panel has been tested for 5 years of outdoor exposure, and the color difference is still less than ΔE2.0, always maintaining the initial refreshing appearance.

What surprised customers even more was that the fiber structure of the rock wool core material in the details was specially combed to avoid the itchy feeling of traditional rock wool. Even if the surface of the board is directly touched during transportation or daily cleaning, it will not scratch the skin. The board seams are filled with weather-resistant sealant, which not only blocks the penetration of hot and cold air, but also prevents rainwater from seeping in. Even in the rainy season in Queensland, there is no leakage in the outdoor office area.

From parameter adaptation in the design stage to on-site guidance at the time of delivery, the Yirong team used the dual-track thinking of Australian standards and local needs to create a safe, heat-insulating and fire-proof office for customers. Yirong sandwich panel supplier uses a 75mm thick rock wool fireproof panels, which not only completes the leap from material supplier to safety solution service provider, but also allows China's intelligent fire safety to take root and grow in the land of the southern hemisphere.
