As its name suggests, handcrafted rock wool boards are designed for specific applications. Over time, this product has been continuously refined, gaining an ever-expanding range of functions. To help more people become familiar with it, we’ll now walk you through the key considerations for using handcrafted rock wool boards. If you’re curious, let’s take a look—hopefully, this information will be helpful to you.

When using hand‑crafted rock wool boards, prioritize rain protection and avoid working on rainy days. To ensure effective thermal insulation, apply an additional moisture‑proof layer. In extremely low‑temperature conditions, use resin‑free rock wool for insulation, and make sure the moisture barrier is fire‑resistant as well. When the temperature exceeds a specified threshold—such as 200°C—provide appropriate external protection to prevent changes in the board’s thickness and density. For insulating large‑diameter, flat‑wall equipment with rock wool products, always follow the manufacturer’s instructions when temperatures exceed 200°C: install insulation anchors and ensure the outer cladding is tightly sealed.

When using hand‑crafted rock wool boards, it is also necessary to employ insulating equipment and insulation nails, and the pipes can be coated with an appropriate protective finish to enhance corrosion resistance. Furthermore, no leaks should occur; this will ensure better performance. For finished hand‑crafted rock wool boards subjected to outdoor thermal insulation, where they are prone to mechanical abrasion, they should be covered with metal or plastic sheathing. Attention should then be paid to the joints: ensure proper sealing, applying sealant if needed, and provide a lap of at least 100 mm on the overlapping sections of the covering layer. When the insulated object is positioned at a 90° angle and has a certain height, the rock wool insulation layer must be secured with locating pins or support rings, spaced no more than 3 meters apart, to prevent vibration that could cause the insulation material to slip. To minimize heat loss, the joints between hand‑crafted rock wool boards and felt must be tightly sealed. If multiple insulation layers are used, cross‑overlapping joints should be wrapped around one another to avoid thermal bridges. During cold‑storage applications, cold bridges must be strictly avoided.

Prior to installation, hand‑crafted rock wool boards shall be installed in accordance with the design specifications, the requirements of this code, and relevant technical standards. A dedicated energy‑saving and thermal‑insulation construction plan for this project must be prepared, and all workers must receive a thorough technical briefing and specialized training. During installation, operators must wear appropriate personal protective equipment, observe occupational health and safety measures, and ensure construction safety. The manufacturer of the rock wool board external insulation system shall assign qualified personnel to provide on‑site guidance throughout the construction process, coordinating closely with the contractor and the site supervisor to ensure effective quality control.
