Product Overview: Acoustic Rock Wool Panel Board
Acoustic rock wool panel board (also known as sound absorbing mineral wool panel or rockwool acoustic board) represents a semi-rigid, high-density insulation board composed of fine fibers spun from molten basalt rock and blast furnace slag.
Specifically, the fibers are bonded with a thermosetting resin and formed into rigid panels with precisely controlled density and thickness.
Consequently, this structure delivers exceptional sound absorption, thermal insulation, and fire protection performance for acoustic ceiling panels, wall acoustic panels, and industrial noise control applications.
TARCO Industry produces its acoustic rock wool panel board from high-quality basalt rock and blast furnace slag, melting these raw materials at temperatures exceeding 1500°C. During production, we fiberize the molten rock using high-speed spinning wheels and apply a hydrophobic binder to create a water-repellent board. Ultimately, the product is precision-cut into panels and can be supplied with various facings including black glass fiber veil, aluminum foil, or natural finish to suit specific acoustic and aesthetic requirements.
Key Features & Benefits of Acoustic Rock Wool Panel Board
Furthermore, acoustic rock wool panel board offers exceptional sound absorption with a Noise Reduction Coefficient (NRC) ranging from 0.75 to 1.05.
Additionally, the product achieves Euroclass A1 non-combustible fire classification per EN 13501-1, the highest possible fire rating, contributing no fuel to a fire.
Moreover, rock wool panel board provides excellent thermal insulation with low thermal conductivity values ranging from 0.033 to 0.049 W/m·K.
Consequently, the dense fiber structure delivers superior acoustic performance across a wide frequency range, with flow resistivity values between 8,000 and 40,000 Pa·s/m².
Therefore, the hydrophobic binder ensures water repellency greater than 98%, preventing moisture absorption and maintaining acoustic and thermal performance over time.
In addition, rock wool panel board is chemically inert, rot-proof, vermin-proof, and resistant to microbial growth for long service life.
Furthermore, the product is asbestos-free and safe to handle, with fibers classified as IARC Group 3 (not classifiable as carcinogenic to humans).
Finally, acoustic rock wool panel board can be supplied with various facings including black glass fiber veil, aluminum foil, or natural finish for enhanced acoustic performance and aesthetic appeal.
