Products like hand‑crafted rock wool boards are typically used in industrial settings; most of us have neither seen nor heard of them, and they’re not commonly encountered in everyday life. Nevertheless, they play an indispensable role in industry. When using them, the first step is to understand their key advantages—let’s explore those together.
Handcrafted rock wool boards fully leverage the unique properties of rock wool core materials, delivering outstanding performance in fire resistance, thermal insulation, sound absorption, and sound insulation. Their superior fire‑resistance is attributable to the raw materials, manufacturing processes, and formulation used in these panels; tests have demonstrated a fire‑resistance rating exceeding 1,000°C. Furthermore, these handcrafted rock wool boards have successfully passed testing by the certification body GLOROANOS.P.A.
Test results are as follows: 1) 50 mm thick rock wool sandwich panel: RE 130; 80 mm thick rock wool sandwich panel: REL 60; 100 mm thick rock wool sandwich panel: REL 120. Excellent thermal insulation performance: The thermal insulation and heat‑retention properties of rock wool sandwich panels are based on a thermal conductivity of 0.043 W/m·K for the rock wool core, calculated according to the corresponding core thicknesses.
Handcrafted rock wool boards deliver outstanding sound absorption and thermal insulation. In terms of soundproofing, they effectively reduce noise transmission, making them particularly suitable for areas frequented by aircraft. Moreover, when used as roofing panels, they significantly attenuate indoor noise caused by rain and hail impacting the building’s steel roof deck. Testing in accordance with ISO 717/82 and UNI 8270/7 standards shows that sandwich panels with a rock wool core and a density of 120 kg/m³ can achieve a sound reduction rating (Rw) of 29–30 dB. Acoustic performance: Rock wool sandwich panels also exhibit excellent sound‑absorbing properties, effectively dampening a broad range of frequencies.
According to the standard, the sound absorption performance of the hand‑crafted rock wool board reaches DELTALA = 15.7 dB(A), and the fixing method is both secure and well‑designed: the rock wool roof panels are fastened to the purlins using dedicated M6 self‑tapping screws, providing effective resistance to external forces such as typhoons. Self‑tapping screws are positioned at the wave crests on the panel’s upper surface, and a specialized waterproofing structure is employed to eliminate potential weak points in the waterproofing system.
At present, the widespread use of handcrafted rock wool boards in everyday life, coupled with their continually improving manufacturing technologies, gives us reason to believe that more and more manufacturers will enter the market. Therefore, we should keep a close eye on developments and make careful comparisons.
